CVE-2026-43026

CVE-2026-43026 concerns the Linux kernel netfilter ctnetlink path: when CTA_EXPECT_NAT is absent, ctnetlink_alloc_expect() can leave saved_addr and saved_proto uninitialized, risking leakage of stale data. The safe nf_ct_expect_init() in the packet path zeros these fields, and the patch adds expl...

CVE-2026-43035

The CVE affects the Linux kernel net: sched: cls_api code path tc_chain_fill_node, where tcm_info in struct tcmsg was not initialized, leaking heap memory to userspace via a 4-byte field. The fix zeros tcm_info alongside other initialized fields. Affected/patched details from connected docs: upst...

CVE-2026-43036

Summary (CVE-2026-43036) : The issue resides in the Linux kernel networking path, where gso_features_check() read IPv4 header offsets (iph->frag_off) in a way that could dereference uninitialized data when packets are injected via PF_PACKET paths. The root cause is unsafe header dereferencing ...

CVE-2026-43049

CVE-2026-43049 affects the Linux kernel HID logitech-hidpp driver (Logitech G920 force feedback).

CVE-2026-43050 describes a race in the Linux kernel’s ATM lec code. A race between lec_atm_close() clearing priv->lecd and concurrent access in send_to_lecd(), lec_handle_bridge(), and lec_atm_send() can cause a use-after-free on the lecd pointer when a socket is freed via RCU. The fix convert...

CVE-2026-43065

CVE-2026-43065 concerns the Linux kernel ext4 subsystem. The issue arises in ext4_mb_release() where, if a filesystem is mounted with -o discard and files are deleted, sbi->s_discard_list accumulates and s_discard_work is queued; if the filesystem is later remounted with nodiscard and the EXT4...

CVE-2026-43111

CVE-2026-43111 describes a use-after-free in the Linux kernel HID roccat driver. The function roccat_report_event() traverses the device->readers list without holding the readers_lock mutex, allowing a concurrent roccat_release() to remove and free a reader still in use. The consequence is a u...

CVE-2026-43133

Summary: CVE-2026-43133 affects Linux kernel KVM’s nested virtualization (nSVM). When an L2 guest executes VMSAVE/VMLOAD and is not intercepted by L1, KVM may incorrectly use vmcb02 instead of vmcb01 for guest state handling due to an oversight in VMLOAD/VMSAVE emulation after a patch. The root c...

CVE-2026-43279

The CVE-2026-43279 entry concerns the Linux kernel ALSA USB-audio subsystem. A discrepancy between playback and capture stream setups (e.g., USB core max packet size) can cause out-of-bounds writes to the buffer, potentially crashing the system. A fix was implemented by adding a sanity check of t...

CVE-2026-43297

The CVE-2026-43297 issue affects the Linux kernel rockchip: rga driver. rga_get_frame() can return ERR_PTR(-EINVAL) for unsupported/invalid buffer types, and rga_buf_init() may dereference that pointer without checking the error, leading to a crash. The fix adds proper ERR_PTR checking in rga_buf...

CVE-2026-43312

CVE-2026-43312 is a Linux kernel vulnerability in the ov5647 V4L2 I2C driver. The issue arises from calling v4l2_get_subdevdata in ov5647_init_controls() before the subdevice is initialized by v4l2_i2c_subdev_init() during probe, which can dereference i2c_client and cause a segfault if an error p...

CVE-2026-43330

CVE-2026-43330 relates to the Linux kernel crypto/caam path, where an overflow occurs when a long HMAC key (longer than the block size) is copied for hashing.

CVE-2026-43418

CVE-2026-43418 describes a race in the Linux kernel sched/mmcid subsystem: when new tasks are created concurrently, a newly forked task is counted as an MMCID user before it is visible in thread and task lists, which can lead to an incorrect CID allocation and potentially a machine stall. The mit...

CVE-2026-43445

CVE-2026-43445 is a Linux kernel vulnerability in the e1000/e1000e drivers (and potentially igbvf) where a DMA mapping error cleanup leak could occur. The root cause was an off-by-one condition in the dma_error path: count was decremented before the loop, so if any TX buffer mappings succeeded be...
