| CVE-2026-16871 | 1 Ibm | 1 I | 2026-08-13 | 4.3 Medium |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to obtain sensitive information due to a heap buffer overflow. | ||||
| CVE-2026-64270 | 1 Linux | 1 Linux Kernel | 2026-08-13 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: Input: mms114 - reject an oversized device packet size mms114_interrupt() reads a packet of touch data from the device into a fixed-size on-stack buffer struct mms114_touch touch[MMS114_MAX_TOUCH]; which holds MMS114_MAX_TOUCH (10) events of MMS114_EVENT_SIZE (8) bytes, i.e. 80 bytes. The length of the I2C read into it is taken verbatim from the device: packet_size = mms114_read_reg(data, MMS114_PACKET_SIZE); if (packet_size <= 0) goto out; ... error = __mms114_read_reg(data, MMS114_INFORMATION, packet_size, (u8 *)touch); packet_size is a single device register byte (0x0F) and the only check is the lower bound packet_size <= 0; it is never bounded against the size of touch[]. A malfunctioning, malicious or counterfeit controller (or an attacker tampering with the I2C bus) can report a packet_size of up to 255, so __mms114_read_reg() writes up to 175 bytes past the end of touch[] on the IRQ-thread stack: a stack out-of-bounds write that can overwrite the stack canary, saved registers and the return address. A well-formed device never reports more than the buffer holds, so reject an oversized packet and drop the report, consistent with the handler's other error paths, rather than reading past the buffer. | ||||
| CVE-2026-64273 | 1 Linux | 1 Linux Kernel | 2026-08-13 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: Input: iforce - bound the device-reported force-feedback effect index iforce_process_packet() handles a status report (packet id 0x02) by taking a force-feedback effect index straight from the device wire and using it to address the per-effect state array: i = data[1] & 0x7f; if (data[1] & 0x80) { if (!test_and_set_bit(FF_CORE_IS_PLAYED, iforce->core_effects[i].flags)) ... } else if (test_and_clear_bit(FF_CORE_IS_PLAYED, iforce->core_effects[i].flags)) { ... } The index is masked only with 0x7f, so it ranges 0..127, but core_effects[] holds only IFORCE_EFFECTS_MAX (32) entries. For an index of 32..127 the test_and_set_bit()/test_and_clear_bit() is an out-of-bounds single-bit read-modify-write past the array. core_effects[] is the second-to-last member of struct iforce, so the write lands in the trailing members and beyond the embedding kzalloc()'d iforce_serio / iforce_usb object. data[1] is unvalidated device payload on both transports (the USB interrupt endpoint and serio), and the status path is not gated on force feedback being present, so a malicious or counterfeit device can set or clear a bit at an attacker-chosen offset past the object. Reject an out-of-range index instead of indexing with it. Bound against the array dimension IFORCE_EFFECTS_MAX rather than dev->ff->max_effects so the check guarantees memory safety regardless of how many effects the device registered. A legitimate "effect started/stopped" status always carries an index below IFORCE_EFFECTS_MAX, so well-formed devices are unaffected; the neighbouring mark_core_as_ready() loop is already bounded and is left untouched. | ||||
| CVE-2026-64274 | 1 Linux | 1 Linux Kernel | 2026-08-13 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: Input: goodix - clamp the device-reported contact count goodix_ts_read_input_report() copies the number of touch points reported by the device into an on-stack buffer u8 point_data[2 + GOODIX_MAX_CONTACT_SIZE * GOODIX_MAX_CONTACTS]; which is sized for at most GOODIX_MAX_CONTACTS (10) contacts. The only runtime check bounds the per-interrupt count against ts->max_touch_num, but that value is taken verbatim from a 4-bit field of the device configuration block and is never clamped: ts->max_touch_num = ts->config[MAX_CONTACTS_LOC] & 0x0f; The nibble can be 0..15, so a malfunctioning, malicious or counterfeit controller (or an attacker tampering with the I2C bus) can advertise up to 15 contacts. goodix_ts_read_input_report() then accepts a touch_num of up to 15 and the second goodix_i2c_read() writes ts->contact_size * (touch_num - 1) bytes past the one-contact header into point_data - up to 30 bytes (45 with the 9-byte report format) beyond the 92-byte buffer: a stack out-of-bounds write. Clamp max_touch_num to GOODIX_MAX_CONTACTS, the number of contacts point_data[] is sized for, when reading it from the configuration. | ||||
| CVE-2026-64276 | 1 Linux | 1 Linux Kernel | 2026-08-13 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: Input: synaptics-rmi4 - bound the F30 keymap to the GPIO/LED count rmi_f30_map_gpios() allocates gpioled_key_map with min(gpioled_count, TRACKSTICK_RANGE_END) == at most 6 entries, but rmi_f30_attention() iterates the full f30->gpioled_count (device query register, range 0..31) and dereferences gpioled_key_map[i], and input->keycodemax is set to the full gpioled_count while input->keycode points at the 6-entry allocation. A device that reports gpioled_count > 6 with GPIO support enabled therefore causes an out-of-bounds read on the attention interrupt and out-of-bounds read/write through the EVIOCGKEYCODE/EVIOCSKEYCODE ioctls, which bound the index only against keycodemax. This is the same defect as the F3A handler, which was copied from F30. Size the keymap for the full gpioled_count; the mapping loop still assigns only the first min(gpioled_count, TRACKSTICK_RANGE_END) entries. | ||||
| CVE-2026-17218 | 1 Ibm | 1 I | 2026-08-13 | 9.8 Critical |

| CVE-2026-73072 | 1 Vim | 1 Vim | 2026-08-13 | 7.8 High |
| Vim is an open source, command line text editor. Prior to 9.2.0846, set_sofo() in src/spellfile.c reuses sl_sal_first[] without resetting values left by set_sal_first(), so a crafted spell file containing an SN_SAL section before an SN_SOFO section causes under-counted mapping lists and attacker-influenced writes beyond a heap allocation. This issue is fixed in version 9.2.0846. | ||||

| CVE-2026-18888 | 1 Mongodb | 1 Bi Connector Odbc Driver | 2026-08-13 | 6.5 Medium |
| The MongoDB BI Connector ODBC Driver converts floating point column values into text without checking that the result fits within the destination buffer. When an application reads a sufficiently large floating point value as text, the driver may write beyond the end of that buffer and corrupt adjacent memory. A user who can store data in a collection read through the BI Connector could use this to crash the application performing the read. | ||||
| CVE-2026-64285 | 1 Linux | 1 Linux Kernel | 2026-08-13 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: KVM: SEV: Pin source page for write when adding CPUID data for SNP guest When populating a guest_memfd instance with the initial CPUID data for an SNP guest, acquire a writable pin on the source page as KVM will write back the "correct" CPUID information if the userspace provided data is rejected by trusted firmware. Because KVM writes to the source page using a kernel mapping, pinning for read could result in KVM clobbering read-only memory. Note, well-behaved VMMs are unlikely to be affected, as CPUID information is almost always dynamically generated by userspace, i.e. it's unlikely for the CPUID information to be backed by a read-only mapping.

| CVE-2026-18725 | 1 Open-iscsi Project | 1 Open-iscsi | 2026-08-13 | 6.3 Medium |
| AI_ONLY_REPORT package: iscsi-initiator-utils-6.2.1.11-0.git4b3e853.el10 ------ Summary: Out-of-Bounds Write and Information Disclosure via Unvalidated IPv6 Payload Length: crafted ICMPv6 Echo Requests can cause `iscsiuio` to trust an inflated `ipv6_plen` larger than the actual received payload, leading to MTU-bounded out-of-bounds reads and a potential one-byte out-of-bounds write that may disclose data beyond the valid packet boundary. Requirements to exploit: Adjacent-network access on the same L2 segment as a system running `iscsiuio` on an interface that processes IPv6/NDP traffic, plus the ability to send a crafted ICMPv6 Echo Request with a forged `IPv6.plen`. No authentication or user interaction is required. Component affected: `iscsi-initiator-utils` (`iscsiuio`): `iscsiuio/src/uip/ipv6.c` in `ipv6_icmp_handle_echo_request()` and `ipv6_insert_protocol_chksum()`. Version affected: `iscsi-initiator-utils-6.2.1.11-0.git4b3e853.el10` when `iscsiuio` is processing IPv6/NDP traffic on a reachable interface. Patch available: no released package fix established; proposed patch included below Version fixed: unknown Upstream coordination: Not notified. CVSS: CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L - 6.3 (MEDIUM) AV:A - Reachability is limited to an attacker on the same L2 segment who can send crafted IPv6/ICMPv6 traffic to the affected interface. AC:L - The attack relies on forging `IPv6.plen`; no race or unusual environment is needed beyond the vulnerable deployment. PR:N - No privileges are required. UI:N - No user interaction is required. S:U - The impact remains within the `iscsiuio` process and its packet buffer handling. C:L - The reply/checksum path can read and potentially transmit data beyond the valid packet boundary, but the demonstrated exposure is MTU-bounded. I:L - For odd forged lengths, the checksum path can write a single padding byte past the valid protocol data, which may affect adjacent buffer contents. A:L - Invalid memory access may destabilize or crash the process, but reliable high-impact denial of service is not established from the available evidence. Impact: Moderate. Under Red Hat's severity guidance, this is more consistent with a flaw that can affect confidentiality, integrity, or availability under constrained circumstances than with an Important issue. The bug is unauthenticated and adjacent-network reachable, but the currently supported outcome is MTU-bounded out-of-bounds access in a deployment-dependent IPv6/NDP path, not easy remote system compromise or clearly high-impact memory corruption. Embargo: no Reason: The currently supported impact is Moderate, exposure depends on `iscsiuio` processing IPv6 traffic on a reachable L2 segment, and operators can reduce exposure operationally by isolating or disabling the affected path. Acknowledgement: Aisle Research Vulnerability Details: In the ICMPv6 echo-reply path, the code reuses the inbound `ipv6_plen` field when sizing the reply instead of clamping it to the bytes actually received: ```c /* iscsiuio/src/uip/ipv6.c */ static void ipv6_icmp_handle_echo_request(struct ipv6_context *context) { ... ipv6_send(context, (u8_t *) icmp - (u8_t *) eth + sizeof(struct ipv6_hdr) + HOST_TO_NET16(ipv6->ipv6_plen)); } ``` Later, checksum generation also trusts `ipv6_plen` for memory traversal, and for odd lengths it writes a padding byte at `ptr + protocol_data_len` before iterating over `protocol_data_len` bytes: ```c /* iscsiuio/src/uip/ipv6.c */ protocol_data_len = HOST_TO_NET16(ipv6->ipv6_plen); ... if (protocol_data_len & 1) { *((u8_t *) ptr + protocol_data_len) = 0; protocol_data_len++; } for (i = 0; i < protocol_data_len / 2; i++) { sum += HOST_TO_NET16(*ptr); ptr++; } ``` The available receive-side logic does not establish a payload-length bound strong enough to eliminate this condition. `uip_input()` compares the IPv6 payload length against `uip_len`, but `uip_len` is treated as full frame length in the observed path rather than the actual IPv6 payload length, and `ipv6_rx_packet()` receives a `len` argument without using it to bound parsing. A forged `ipv6_plen` can therefore exceed the real IPv6 payload stored in the buffer. The available evidence supports MTU-bounded out-of-bounds access in normal receive paths rather than the earlier arbitrary 64KB worst case. The affected logic appears to be present in the available 6.2.1.11 code base, but this report is scoped to the scanned SRPM package. Steps to reproduce: 1. Build `iscsiuio` with ASAN enabled. 2. Run `iscsiuio` with IPv6/NDP active on a test interface. 3. From the same L2 segment, send an ICMPv6 Echo Request with `IPv6.plen` set larger than the actual payload bytes in the frame buffer; one tested shape is `plen=1491` with an Ethernet frame size near 1500 bytes. 4. Observe the reply path: ASAN reports invalid access in `ipv6_insert_protocol_chksum()` as the checksum walk reads past valid packet data, odd lengths may also trigger a one-byte write, and reply sizing is derived from the forged `ipv6_plen` rather than the actual received payload size. Mitigation: Until a fix is available, keep `iscsiuio`-managed interfaces on trusted L2 segments only. Where operationally acceptable, disable IPv6 on those interfaces or filter ICMPv6 Echo Requests before they reach `iscsiuio`. If `iscsiuio` is not processing IPv6/NDP traffic, this specific path is not reachable. Proposed Fix: Clamp the reply payload length to the actual received payload derived from `context->ustack->uip_len`, reject packets too short to contain a complete ICMPv6 header, and rewrite `ipv6->ipv6_plen` before calling `ipv6_send()`. ```diff diff --git a/iscsiuio/src/uip/ipv6.c b/iscsiuio/src/uip/ipv6.c @@ -1100,6 +1100,8 @@ static void ipv6_icmp_handle_echo_request(struct ipv6_context *context) { struct eth_hdr *eth = (struct eth_hdr *)context->ustack->data_link_layer; +u16_t rx_total, rx_payload, hdr_plen, safe_plen; +u16_t l2_l3_len = sizeof(struct eth_hdr) + sizeof(struct ipv6_hdr); struct ipv6_hdr *ipv6 = (struct ipv6_hdr *)context->ustack->network_layer; struct icmpv6_hdr *icmp = (struct icmpv6_hdr *)((u8_t *)ipv6 + @@ -1126,8 +1128,20 @@ static void ipv6_icmp_handle_echo_request(struct ipv6_context *context) icmp->icmpv6_code = 0; icmp->icmpv6_cksum = 0; ILOG_DEBUG("IPv6: Send echo reply"); -ipv6_send(context, (u8_t *) icmp - (u8_t *) eth + sizeof(struct ipv6_hdr) + HOST_TO_NET16(ipv6>ipv6_plen)); + +rx_total = context->ustack->uip_len; +if (rx_total <= l2_l3_len) +return; + +rx_payload = rx_total - l2_l3_len; +hdr_plen = HOST_TO_NET16(ipv6->ipv6_plen); +safe_plen = (hdr_plen <= rx_payload) ? hdr_plen : rx_payload; +if (safe_plen < sizeof(struct icmpv6_hdr)) +return; + +ipv6->ipv6_plen = HOST_TO_NET16(safe_plen); +ipv6_send(context, l2_l3_len + safe_plen); + return; } ``` ------ This report was generated using AI technology.
