CVE-2026-97618 1 Linux 1 Linux Kernel 2026-10-03 7.0 High
In the Linux kernel, the following vulnerability has been resolved: io_uring/net: don't overconsume buffers when using MSG_TRUNC When a recv/recvmsg is issued with MSG_TRUNC and the incoming packet is larger than the provided buffer, the net layer returns the full length of the packet rather than the number of bytes actually copied into the buffer. As a result, io_uring advances more of the provided buffer ring than was actually filled. Use the actual filled region size to consume the buffer, but still return the full size to preserve MSG_TRUNC semantics. Take care with multishot, because that seems to already truncate the consumption based on the available payload size. This was reported in https://github.com/axboe/liburing/issues/1619.

CVE-2026-97612 1 Linux 1 Linux Kernel 2026-10-03 7.8 High
In the Linux kernel, the following vulnerability has been resolved: net: mpls: clear inner_protocol when the last label is popped skb_mpls_push() records the pre-encapsulation network header once, gated on !skb->inner_protocol. skb_mpls_pop() never clears that record, so it outlives the encapsulation it describes. Open vSwitch can then re-push MPLS onto a packet whose inner_network_header still points at the older, deeper offset: push a label, pop every label, recirculate (ovs_flow_key_update() re-derives key->eth.type and resets network_header, but leaves inner_*), then push again. ovs_fragment() trusts the record: skb->network_header = skb->inner_network_header; so skb_network_offset() goes negative. The bound check is signed: if (skb_network_offset(skb) > MAX_L2_LEN) a negative offset passes it, and prepare_frag() widens the value: unsigned int hlen = skb_network_offset(skb); memcpy(&data->l2_data, skb->data, hlen); which is a ~4GiB memcpy out of a 30-byte per-CPU buffer. Reproduced on v7.3-rc1. RDX is the truncated length, (unsigned int)(-8): BUG: unable to handle page fault for address: ffffe8ffffc16000 #PF: supervisor write access in kernel mode Oops: 0002 [#1] SMP KASAN NOPTI RIP: 0010:memcpy+0x8/0x20 RDX: 00000000fffffff8 RSI: ffff888105d732db RDI: ffffe8ffffc16000 prepare_frag+0x3df/0x4e0 ovs_fragment+0x589/0x7e0 do_output+0x4ce/0x5e0 do_execute_actions+0x55d2/0x7b30 ovs_execute_actions+0xea/0x450 Same root-cause shape as commit 975b5b067f52 ("ipv6: sr: restore network header before routing and forwarding"): a stale network header offset reaching a consumer that widens it. Here it originates in the MPLS push/pop path. Clear inner_protocol once the packet is no longer MPLS, so a later push re-records the current header. net/sched/act_mpls.c is the only other skb_mpls_pop() caller and gets the same fix; sch_frag.c saves and restores inner_protocol around fragmentation in the same way OVS does.
CVE-2026-93287 1 Linux 1 Linux Kernel 2026-10-03 7.8 High
In the Linux kernel, the following vulnerability has been resolved: i2c: smbus: reject oversized block transfers in the common path The SMBus block transfer length data->block[0] is validated in i2c_smbus_xfer_emulated() but that check runs too late for tracepoints and is skipped entirely when the adapter provides a native smbus_xfer implementation. This allows user-controlled oversized block lengths to reach tracepoint memcpy calls and driver callbacks unchecked. Add an early validation in __i2c_smbus_xfer() that rejects block transfers whose caller-supplied length is zero or exceeds I2C_SMBUS_BLOCK_MAX before any tracepoint fires or driver callback runs. data->block[0] is filled in by the device on SMBus block reads, so the check is scoped to operations where the length is actually supplied by the caller. This is consistent with the existing -EINVAL convention in the emulated path and protects all downstream consumers at once: the smbus_write tracepoint, all native smbus_xfer driver implementations, and the emulated path. Two distinct bugs are fixed by this change: Bug 1: smbus_write tracepoint OOB (include/trace/events/smbus.h) trace_smbus_write() fires before any validation and copies data->block[0]+1 bytes into a 34-byte event buffer. With block[0]=0xfe the tracepoint copies 255 bytes, overflowing by 221.

CVE-2026-103923 1 Katex 1 Katex 2026-10-01 4.7 Medium
KaTeX is a fast, easy-to-use JavaScript library for TeX math rendering on the web. From 0.11.0 until 0.18.2, KaTeX uses ordinary JavaScript property access for the renderer options object, the trust setting, default and processor setting metadata, and namespace lookup and group restoration, allowing inherited properties to be treated as explicitly supplied values. When Object.prototype is already polluted or an attacker controls the options object's prototype, attacker-controlled mathematical expressions can use an inherited trust value to enable trusted rendering and produce links capable of user-interaction cross-site scripting or loading attacker-selected external resources in a consuming application that inserts unsanitized KaTeX output into a page. KaTeX does not itself create the prototype pollution, and rendering an expression alone does not execute script. This issue is fixed in version 0.18.2.

CVE-2026-102117 1 Kiteworks 1 Core 2026-10-01 7.2 High
On deployments where the remote-support capability is licensed and enabled, an authenticated System Administrator who also possessed the key protecting the submitted data could redirect the underlying system's outbound support connection to a destination of their choosing. That destination could then have operating-system commands executed on the node and receive their output, potentially resulting in remote code execution with the privileges of a local service account.

CVE-2026-63216 1 Zammad 1 Zammad 2026-09-29 N/A
Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, unsanitized option labels are rendered in the configuration dialogs of AI Agents within Zammad's admin UI. When rendering the list of selected options, the option label is output as raw HTML without escaping. An attacker who can control an option label, for example by setting a malicious string as a user or organization name used in a relation attribute, or by supplying a crafted custom attribute option value, can inject arbitrary HTML and JavaScript. The payload executes in the browser of any admin or agent who opens the affected object attribute configuration view. This issue is fixed in version 7.1.2.
CVE-2026-102279 1 Laravel 1 Framework 2026-09-29 3.1 Low
Laravel is a web application framework. Prior to 12.69.0 and 13.30.0, Laravel exception debug pages with APP_DEBUG=true pass attacker-controlled input to a Tippy.js tooltip configured with allowHTML true, enabling DOM-based cross-site scripting when a user hovers over the tooltip. This issue is fixed in versions 12.69.0 and 13.30.0.
