| CVE-2026-90346 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: clean up color-change beacon data on errors nl80211_color_change() calls nl80211_parse_beacon() for the beacon_next template, which can allocate params.beacon_next.mbssid_ies and .rnr_ies. A parsing failure returned directly instead of using the out: cleanup, leaking any allocations completed before the error. Allocate the nested attribute table before parsing beacon_next. Its allocation failure can then return before beacon data exists, while a later parsing failure uses out: to release the parsed data. | ||||

| In the Linux kernel, the following vulnerability has been resolved: wifi: ath10k: snoc: use memcpy_fromio() for MSA ramdump On WCN3990/SNOC the MSA region is mapped with devm_memremap(MEMREMAP_WT). On arm64 such a mapping is not Normal-cacheable, so unaligned accesses to it are not permitted. ath10k_msa_dump_memory() copies the region with a plain memcpy(), whose optimized __pi_memcpy_generic implementation issues wide/unaligned loads. This triggers an alignment fault (FSC=0x21) Oops in ath10k_snoc_fw_crashed_dump() while collecting the devcoredump: Unable to handle kernel paging request ... FSC=0x21: alignment fault pc : __pi_memcpy_generic lr : ath10k_snoc_fw_crashed_dump [ath10k_snoc] The Oops both leaves the firmware RAM dump buffer zeroed (no dump is captured) and crashes the kernel, which in turn breaks modem SSR recovery. Use memcpy_fromio(), which only performs accesses that are valid for such a device-memory mapping. The generic memcpy_fromio() implementation aligns the source before issuing word-sized reads and stores the destination with put_unaligned(), so it is also safe for the coherent DMA allocation used on the non-reserved-memory path. ath11k and ath12k use the same pattern when copying target memory into crash dumps, so call it unconditionally here too. The MEMREMAP_WT pointer is a plain void *, so an explicit __iomem cast is needed; use __force to keep sparse happy. Tested-on: WCN3990 hw1.0 SNOC WLAN.HL.3.3.7.c5-00107-QCAHLSWMTPL-1 | ||||
| CVE-2026-90350 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: reject out-of-range link ids in mt76_vif_link() mt76_vif_link() indexes mvif->link[] without validating link_id, but callers pass mvif->deflink_id / msta->deflink_id, which hold IEEE80211_LINK_UNSPECIFIED (0xf) until the first link has been added. Since IEEE80211_MLD_MAX_NUM_LINKS is 15, that reads one element past the end of the array, aliasing mt76_vif_data.offchannel_link. Reachable via mt7996_set_tsf()/mt7996_offset_tsf() and mt7996_net_fill_forward_path(). Bounds check link_id and return NULL, matching mt7996_sta_link() and mt7996_sta_link_protected(). | ||||
| CVE-2026-90352 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: release hif2 reference on probe IRQ failure The hif2 reference obtained by mt7915_pci_init_hif2() is only released on error paths that key off dev->hif2, which is not assigned until after the IRQ setup. If pci_alloc_irq_vectors() or the primary devm_request_irq() fails, the reference leaks. Drop it explicitly on those paths via mt7915_put_hif2(). | ||||
| CVE-2026-90355 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: clear stale link state on full reset After a full chip reset, mac80211 reconfig replays interface, link and channel context setup. mt7996_vif_link_add() short-circuits when the link_id is still marked in mvif->valid_links, a state introduced for postponing link teardown to interface removal. The reset path frees the link structures without clearing those bits, so the replayed setup never re-creates dev_info/bss_info/STA records in the restarted firmware and never re-registers the link wcid, leaving the device inoperative. The reset path also leaks every allocated MLD index: per-link indices and the per-vif group/remap indices are re-allocated from scratch during reconfig, but the old bits stay set in the masks, so repeated full resets exhaust the index space. Clear valid_links in the reset vif iterator and reset the MLD index masks alongside the existing omac_mask clearing. | ||||
| CVE-2026-90259 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: btrfs: qgroup: fix a wrong length calculation in qgroup_free_reserved_data() In that function, we round down the start position and round up the ending position. But during the calculation of @len, we use "round_up(start + len, sectorsize)", which is the rounded up end position, not the rounded up length. Which results a much larger length, and later we are still using "start + len", which is completely incorrect. Fix it by declaring a local @aligned_start and @aligned_len and use them instead. | ||||

| CVE-2026-90269 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: bpf: Reject load-acquire from pointers requiring fault protection A BPF_LOAD_ACQ is not rewritten to a BPF_PROBE_MEM load by the verifier, unlike a regular BPF_LDX, so the JIT emits a plain load with no exception table entry and a fault panics the kernel instead of being handled. Reject the source pointer types that a BPF_LDX would have had that fault protection applied to, i.e. the ones bpf_convert_ctx_accesses() turns into BPF_PROBE_MEM: a bare PTR_TO_BTF_ID, PTR_TO_BTF_ID | PTR_UNTRUSTED, PTR_TO_BTF_ID | MEM_ALLOC | PTR_UNTRUSTED and PTR_TO_MEM | MEM_RDONLY | PTR_UNTRUSTED. This is reachable e.g. by loading ->mm out of a trusted task_struct yields an untrusted pointer to mm_struct, and it is NULL for a kernel thread: [...] SEC("tp_btf/sched_switch") int BPF_PROG(demo, bool preempt, struct task_struct *prev, struct task_struct *next) { struct mm_struct *mm = next->mm; /* untrusted */ out_ldx = (__u64)mm->pgd; /* BPF_LDX */ out_acq = load_acquire(&mm->pgd); /* BPF_LOAD_ACQ */ return 0; } [...] Both dereference the same pointer, but only the BPF_LDX is protected (x86-64 JIT, jump targets shown prog-relative): [...] ; out_ldx = (__u64)mm->pgd; 17: movq $-10485760, %r10 1e: movq %rsi, %r11 21: addq $184, %r11 28: subq %r10, %r11 2b: movabsq $140737498841088, %r10 35: cmpq %r10, %r11 38: ja 0x3e <-- kernel addr? 3a: xorl %edi, %edi <-- no: dst = 0, skip the load 3c: jmp 0x45 3e: movq 184(%rsi), %rdi <-- yes: load + extable entry [...] ; load_acquire(&mm->pgd) 53: movq %rsi, %rdi 56: movq 184(%rdi), %rax <-- no check, no extable entry [...] Note that BPF_PROBE_MEM is not visible in a bpftool xlated dump, as bpf_insn_prepare_dump() rewrites it back to BPF_MEM. A PTR_TRUSTED pointer is deliberately not on the list. Such a load is not converted either, but it does not need to be, since the pointer is guaranteed live, so load-acquire from it stays allowed. The check is gated on BPF_LOAD_ACQ so that atomic RMW and store-release error messages are unchanged; writes (RMW / store-release) to such pointers are already rejected elsewhere, so only load-acquire needs this. | ||||
| CVE-2026-90271 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: arm_mpam: Fix a NULL pointer dereference on unbinding after an error interrupt If a user unbinds an MSC after mpam_disable() has been run in response to an error interrupt then a dereference of a NULL pointer occurs as mpam_disable() sets the drvdata to NULL. Add an early return to the driver remove callback to avoid this. | ||||
| CVE-2026-90277 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: md/md-llbitmap: prevent create failure bitmap UAF llbitmap_create() publishes mddev->bitmap before reading the bitmap superblock. This is needed because llbitmap_read_sb() can initialize a new bitmap and flush it through helpers that use mddev->bitmap. If llbitmap_read_sb() fails, the old cleanup dropped bitmap_info.mutex and freed llbitmap before clearing mddev->bitmap. Readers such as /proc/mdstat rely on bitmap_info.mutex to keep the bitmap pointer stable while collecting bitmap stats, so they could observe the stale pointer after the failed create path released the mutex. Clear mddev->bitmap while still holding bitmap_info.mutex, then free the failed llbitmap after dropping the mutex. This makes mutex-protected readers see either a live bitmap or no bitmap. | ||||
| CVE-2026-90278 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: md: wait for behind writes before destroying bitmap __md_stop() destroyed the bitmap before calling mddev_detach(). That made mddev_detach() skip bitmap_ops->wait_behind_writes(), because the bitmap was already disconnected from mddev. This was still safe for the legacy bitmap because bitmap_destroy() waits for behind writes itself. llbitmap keeps that wait in its ->wait_behind_writes() operation instead, while ->destroy() tears down the llbitmap storage. With the old ordering, RAID1 behind-write completions could still run after llbitmap storage had been freed. Call mddev_detach() before md_bitmap_destroy() so the common detach path can wait for behind writes while the bitmap is still alive. Only destroy the bitmap after those users are gone. | ||||
| CVE-2026-90280 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: phy: qcom: qmp-usb: Fix possible NULL-deref on early runtime suspend There is a small window where the runtime suspend callback may run after pm_runtime_enable() and before pm_runtime_forbid(). In this case, a crash occurs because runtime suspend/resume dereferences qmp->phy pointer, which is not yet initialized: `if (!qmp->phy->init_count) {` This can also happen if user re-enables runtime-pm via the sysfs attribute before qmp phy is initialized. Similarly to other qcom phy drivers, introduce a qmp->phy_initialized variable that can be used to avoid relying on the possibly uninitialized phy pointer. | ||||
| CVE-2026-90282 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: phy: qcom: qmp-usb-legacy: Fix possible NULL-deref on early runtime suspend There is a small window where the runtime suspend callback may run after pm_runtime_enable() and before pm_runtime_forbid().

| CVE-2026-90356 | 1 Linux | 1 Linux Kernel | 2026-09-19 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7996: free vif links after clearing wcid entries on full reset mt7996_mac_reset_vif_iter() queues non-default vif links for kfree_rcu while dev->wcid[] still holds pointers to the wcid embedded in each freed link; mt76_reset_device() then dereferences those entries and runs mt76_wcid_cleanup() on them. If a grace period elapses in between, the cleanup operates on freed memory. Run mt76_reset_device() first, so the wcid entries are cleaned up and cleared while the links are still valid. | ||||
| CVE-2026-90357 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 8.8 High |
| In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7915: unlink TWT flow if the MCU rejects the agreement The flow is added to dev->twt_list before sending the agreement to the firmware, but the error path leaves it linked while flowid_mask is never set. The flow slot can then be reused and memset while still on the list, corrupting twt_list, and station removal leaves a dangling entry behind that mt7915_mac_twt_sched_list_add() later walks. | ||||
| CVE-2026-90358 | 1 Linux | 1 Linux Kernel | 2026-09-19 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: bpf, x86: Fix trampoline stack size for 128-bit arguments btf_distill_func_proto() accepts a function argument up to 16 bytes, so a 128-bit scalar such as __int128 reaches the x86 trampoline with arg_size == 16. But the current implementation assumes an __int128 argument only needs one register, so the register save area is under-allocated and save_args() overwrites adjacent stack slots. Compute the register count from arg_size for all arguments to fix it. | ||||

| CVE-2026-15815 | 1 Grafana | 2 Grafana, Grafana Enterprise | 2026-09-19 | 8.8 High |
| Grafana OSS and Grafana Enterprise did not safely resolve symbolic links when extracting plugin archives. A crafted plugin archive can chain relative symbolic link entries to escape the plugin installation directory, writing arbitrary files and an executable backend binary outside that directory. The dropped executable runs with the privileges of the Grafana server process, resulting in remote code execution. Plugin archives are extracted before their signature is verified, so a valid plugin signature does not prevent the write. An operator can therefore be affected by installing a plugin that appears legitimate, as well as by installing a plugin from an arbitrary archive using grafana-cli, the GF_INSTALL_PLUGINS environment variable, or preinstall configuration. Grafana Enterprise is affected because it includes the same plugin extraction code as Grafana OSS. | ||||
