CVE-2025-39765

CVE-2025-39765 affects Linux kernel ALSA timer handling. The issue is in snd_utimer_create() where, if kasprintf() returns NULL, snd_utimer_put_id() frees an ID that was never allocated, leading to ida_free() being called on id=0. The root cause is that utimer->id is not guaranteed to be valid...

CVE-2025-39827

CVE-2025-39827 affects the Linux kernel’s rose networking path. The issue arises from two separate reference counting paths for rose_neigh: a numeric count from rose_node structures and a use/refcount_t from rose_sock. The patch merges these into a single lifecycle by incrementing/decrementing ro...

CVE-2025-39846

CVE-2025-39846 : In the Linux kernel, a NULL pointer dereference could occur in PCMCIΑ code during resource allocation. Specifically, __iodyn_find_io_region() assigns pcmcia_make_resource() to res and uses it in pci_bus_alloc_resource(); if pcmcia_make_resource() fails, a dereference of res could...

CVE-2025-39855

Summary: CVE-2025-39855 concerns the Linux kernel ICE driver (notably the E810’s low-latency TX timestamp interface). The bug occurs in ice_ptp_ts_irq() where the Tx timestamp tracker ice_ptp_tx is used before being initialized, risking NULL dereference or use-after-free if a TX timestamp interru...

CVE-2025-39895

CVE-2025-39895: Linux kernel sched_numa_find_nth_cpu() could dereference a null pointer when the CPU mask used by sched_domains_numa_masks does not intersect with the cpus offline. The fix makes the function bail out when bsearch returns NULL instead of dereferencing, preventing a kernel Oops. Af...

CVE-2025-39899

CVE-2025-39899 concerns the Linux kernel mm/userfaultfd path where, on 32-bit ARM with CONFIG_HIGHPTE, move_pages_pte() maps PTE pages using kmap_local_page() and must unmap them in LIFO order. The current code unmapped dst_pte then src_pte in the same sequence, violating LIFO and triggering a ku...

CVE-2025-39905

The CVE-2025-39905 issue affects the Linux kernel phylink path: the race arises from phylink_resolve() manipulating pl->phydev under pl->state_mutex, creating a lock-order inversion with pl->phydev->lock. The fix introduces an explicit lock to serialize concurrent writes to pl->phy...

CVE-2025-39948

The CVE-2025-39948 entry concerns the Linux kernel ice driver. The root cause was a descriptor handling bug in ice_put_rx_mbuf() for multi-buffer/XDP frames: if a descriptor had size 0, those buffers were skipped, so ice_put_rx_buf() wasn’t called, leaving a stale page in the rx ring and potentia...

The fix drains the entire queued list synchronously...

CVE-2026-31492

The CVE-2026-31492 entry concerns the Linux kernel RDMA irdma driver. Root cause: in irdma_create_qp, if ib_copy_to_udata fails, irdma_destroy_qp cleanup waits on free_qp completion that has not been initialized yet. The fix is to initialize the free_qp completion before the ib_copy_to_udata call...

CVE-2026-31506

The CVE-2026-31506 issue concerns the Linux kernel bcmasp component where the Wake-on-LAN (WoL) IRQ handler could be double-freed. The problem stems from handling of the WoL irq; the patch indicates wol_irq does not need explicit freeing because it is allocated with devm_request_irq, and devres h...

CVE-2026-31539

The CVE-2026-31539 entry describes a race condition in the Linux kernel smbdirect module where credits for receive buffers can be granted to a peer that has already consumed them.

CVE-2026-43124

The CVE-2026-43124 issue affects Linux kernel pstore ram_core, where persistent_ram_vmap() could return a non-NULL pointer after vmap() failed, causing persistent_ram_buffer_map() to incorrectly report success and potentially dereference an invalid address on access, leading to a crash (DoS). Roo...

CVE-2026-43144

The CVE-2026-43144 entry concerns the Linux kernel brcmfmac Wi‑Fi SDIO driver. Concrete details from multiple sources show that during SDIO probe failure (e.g., missing firmware), sdiodev->bus could be set to a non-NULL error value twice (in brcmf_sdio_probe() and brcmf_sdiod_probe()), causing...

CVE-2026-43180

The CVE-2026-43180 issue affects the Linux kernel kaweth USB Ethernet driver. The function kaweth_set_rx_mode() improperly manipulates the TX queue by calling netif_stop_queue() followed by netif_wake_queue(), which can wake the TX queue while a tx_urb is still in flight, causing a double usb_sub...

CVE-2026-43195

CVE-2026-43195 affects the Linux kernel component drm/amdgpu related to user queue size handling.

The fix uses a device-managed alloc...

CVE-2026-43251

CVE-2026-43251 affects the Linux kernel HID prodikeys driver. A local attacker can connect a crafted USB device whose report descriptor bypasses the pm->input_ep82 check, leaving input_ep82 NULL and causing a crash (potential DoS). Multiple OSV entries show patches in rootio-linux packages for...

CVE-2026-43253

CVE-2026-43253 relates to the Linux kernel IOMMU AMD component. When iommu.strict=1, the wait_on_sem() busy-wait runs inside a spinlock with interrupts disabled, risking soft lockups under load. The fix moves the completion wait out of the spinlock in iommu_completion_wait(), since wait_on_sem() ...

CVE-2026-43262

CVE-2026-43262 stems from a Linux kernel gfs2 fiemap page fault: gfs2_fiemap() calls iomap_fiemap() while holding the inode glock, risking recursive glock taking if the fiemap buffer maps to the same inode. The fix disables page faults for iomap_fiemap() and faults in the buffer by hand when need...

CVE-2026-43266

The CVE-2026-43266 issue affects the Linux kernel’s ARM CPER/APEI handling: a CPER record with an oversized section_length can cause the kernel to read beyond the intended firmware buffer, leading to a large data dump and potential memory access issues. The fix adds a guard so the kernel stops at...
