CVE-2026-23288

The CVE-2026-23288 issue is in the Linux kernel’s accel/amdxdna component. It describes an out-of-bounds write caused by clearing the command header with memset() before validating the remaining space in a command slot, when the slot space is smaller than the header. The root cause is performing ...

CVE-2026-23331

The CVE-2026-23331 issue concerns the Linux kernel UDP 4-tuple hash table: when an auto-bound UDP socket is bound, connected, and then disconnected, the socket may be moved to a new hash slot without removing the old entry, leaving garbage in the 4-tuple chain. The fix is to remove such a socket ...

CVE-2026-23335

CVE-2026-23335: Linux kernel RDMA/irdma create_user_ah() leak resolved. Root cause: the irdma_create_ah_resp struct contained 4 bytes (rsvd) that were never zeroed, leaking stack memory prior to ib_respond_udata(). Affected code paths thus exposed uninitialized stack content (4 bytes) in the resp...

CVE-2026-23345

The CVE-2026-23345 issue affects the Linux kernel on ARM64 with Graphics Control System (GCS) mappings when FEAT_LPA2 is enabled.

CVE-2026-23407

The CVE-2026-23407 issue affects the Linux kernel AppArmor DFA verification. The root cause is a missing bounds check on DEFAULT_TABLE in verify_dfa(), which can read k = DEFAULT_TABLE[j] as an index without validation when traversing the differential encoding chain, allowing out-of-bounds reads/...

CVE-2026-23446

CVE-2026-23446 affects the Linux kernel aqc111 USB driver. The vulnerability arises when aqc111_suspend uses the PM variant of write_cmd during suspend, causing pm_runtime_resume_and_get to propagate a suspend wait into rpm_resume on the parent, which can block and hang the network stack. The doc...

CVE-2026-23475

CVE-2026-23475 affects the Linux kernel SPI subsystem. The issue was a NULL pointer dereference window in per‑CPU controller statistics: stats were allocated only after controller registration with driver core, so early sysfs access could dereference NULL. The fix moves statistics allocation to t...

CVE-2026-31410

CVE-2026-31410 has concrete patch evidence across multiple OSV entries. Root-OS shows Root:Ubuntu-24.04 and Root:Ubuntu-22.04 patched in the rootio-linux package, with multiple fixed versions available.

CVE-2026-31439

The CVE-2026-31439 entry refers to a Linux kernel issue in dmaengine: xilinx: xdma, where devm_regmap_init_mmio could return an ERR_PTR and the error handling/ messaging were incorrect. The description and connected advisories confirm this is a kernel regression/fix in the regmap init path, with ...

CVE-2026-31452

CVE-2026-31452 affects the Linux kernel ext4 filesystem. Connected sources confirm a concrete vulnerability in inline data storage: when truncate() increases a file beyond the inline capacity, ext4 currently risks the inode inline flag and the file size becoming inconsistent. The fix introduces a...

CVE-2026-31464

Summary (CVE-2026-31464): In the Linux kernel, the scsi: ibmvfc driver is fixed to cure an out-of-bounds access during target discovery. A malicious or compromised VIO server can return a num_written value in the discover targets MAD response that exceeds max_targets. This value is stored directl...

CVE-2026-31484

In the Linux kernel, CVE-2026-31484 is addressed in io_uring/fdinfo: fix OOB read during SQE_MIXED wrap checks in __io_uring_show_fdinfo(). The issue occurred when processing 128-byte SQEs on IORING_SETUP_SQE_MIXED rings: the previous wrap condition (++sq_head & sq_mask) == 0 could pass while the...

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. This could enable resource exhaustion and a DoS condition. The root cause is improper counting of posted recv_io cred...

CVE-2026-31552

CVE-2026-31552 affects the Linux kernel wlcore wifi path. A memory-allocation failure in wl1271_tx_allocate()/wl1271_prepare_tx_frame() could yield -EAGAIN and be misinterpreted by wlcore_tx_work_locked() as a full aggregation buffer, causing a retry loop under wl->mutex with GFP_ATOMIC. This ...

CVE-2026-31553

CVE-2026-31553 affects the Linux kernel KVM on arm64. The issue stems from computing descriptor addresses in __kvm_at_swap_desc() using (u64 __user )hva + offset, which miscomputes when offset ≠ 0, effectively performing offset 8. The correction is to use hva + offset to obtain the correct S1/S2 ...

CVE-2026-31560

CVE-2026-31560 affects the Linux kernel spi-dw-dma path. When completing an SPI transaction, an error in handling a missing device message can lead to a system crash; the recommended fix is to obtain the device from the struct spi_controller* (dev from the controller). The vulnerability has been ...

CVE-2026-31571

The CVE-2026-31571 entry concerns the Linux kernel DRM/I915: unlink_nv12_plane() could clobber plane state after plane_atomic_check() when a Y-plane is repurposed as a normal plane. The fix is to unlink the NV12 planes before computing the new plane state, preventing the race condition that could...

CVE-2026-31674

The CVE-2026-31674 issue affects the Linux kernel netfilter ip6t_rt module, where processing IPv6 routing header (RT) match rules can overflow addrnr if it exceeds IP6T_RT_HOPS. The root cause is rt_mt6() using addrnr outside rtinfo->addrs[] bounds. A patch added validation of addrnr during ru...

CVE-2026-31697

The CVE-2026-31697 entry concerns the Linux kernel crypto: ccp driver. The issue arises when retrieving the CPU ID: if the firmware command fails (notably with an invalid length), copying the firmware ID to userspace can overflow a kernel buffer and leak data to userspace. Public reports describe...

CVE-2026-31730

CVE-2026-31730 affects the Linux kernel fastrpc component, where a double-free of cctx->remote_heap could occur if INIT_CREATE_STATIC ioctl hits an error path and the rpmsg device is removed. The root cause is that fastrpc_init_create_static_process() frees cctx->remote_heap on the err_map ...

CVE-2026-31752

CVE-2026-31752 affects the Linux kernel bridge/networking path: br_nd_send validates IPv6 neighbor discovery options, and a malformed ND option could cause the parser to read beyond the intended option span or read an LLADDR payload that is too short. The issue is mitigated by option-length check...

CVE-2026-31756

Technical details about CVE-2026-31756 are not publicly provided in the connected documents. Monitor for updates from vendors and advisories to confirm affected products, impact, and fixes.

CVE-2026-31759

CVE-2026-31759 affects the Linux kernel USB ULPI path (usb: ulpi) where a double free could occur in ulpi_register_interface() after a failed device_register(), because the error path freed ulpi twice.
