CVE-2026-23315

The CVE affects the Linux kernel mt76 wifi driver (mt76_connac2_mac_write_txwi_80211). The root cause is that the function could perform an out-of-bounds access by not validating the frame length before accessing management fields, including mgmt->u.action.u.addba_req.capab. This could enable ...

CVE-2026-23448

Vulnerability summary (CVE-2026-23448). In the Linux kernel, the net: usb: cdc_ncm path has a bounds-check defect related to NDP16/DPE16 processing. The function cdc_ncm_rx_verify_ndp16() correctly accounts for the NDP offset in the first check, but the second check ignores ndpoffset when validat...

CVE-2026-31420

CVE-2026-31420 affects Linux kernel bridge MRP interval handling. Vulerability arises when br_mrp_start_test/br_mrp_start_in_test accept a user-supplied interval from netlink with no validation; if interval is 0, the delay becomes zero and a tight loop can exhaust memory, causing an OOM kernel pa...

CVE-2026-31509 affects the Linux kernel NFC NCI subsystem. The vulnerability stems from nci_close_device() flushing rx_wq and tx_wq while holding req_lock, creating a circular locking dependency with nci_rx_work() and related paths. The fix moves the rx_wq flush to after req_lock is released, rel...

CVE-2026-31516

The CVE-2026-31516 relates to the Linux kernel XFRM subsystem. A race occurs during net namespace teardown when a work item (policy_hthresh.work) queued by XFRM_MSG_NEWSPDINFO may run after the netns is freed, allowing xfrm_hash_rebuild() to dereference a freed struct net (potential use-after-fre...

CVE-2026-31530

The CVE-2026-31530 entry is backed by concrete details in the connected documents: in the Linux kernel’s cxl subsystem, the vulnerability stems from a use-after-free of parent_port during cxl_detach_ep() when removing CXL memory devices. The root cause is the absence of a lifetime guarantee betwe...

CVE-2026-31570

CVE-2026-31570 relates to the Linux kernel CAN gateway module. The vulnerability is an OOB heap access in cgw_csum_crc8_rel(), caused by looping and writing using raw s8 indices (from_idx/to_idx/result_idx) instead of the precomputed bounds-safe values (from/to/res). calc_idx() yields bounds-safe...

CVE-2026-45867

The CVE-2026-45867 issue affects the Linux kernel power_supply subsystem (act8945a) and is caused by a race condition: requesting the IRQ with the devm_ path before the devm_ path that registers the power_supply handle can lead to use-after-free when the IRQ fires after the power_supply object is...

CVE-2026-45916

CVE-2026-45916 affects the Linux kernel power_supply (sbs-battery) driver. The issue is a race between IRQ handling and power_supply handle lifecycle: requesting IRQ with devm_ before allocating/registering the power_supply handle can cause an interrupt after the handle is freed but before IRQ un...

CVE-2026-45918

CVE-2026-45918 concerns a race condition in the Linux kernel related to OpenVPN TCP handling. When a peer is kept alive and later removed, the kernel temporarily places the peer in a release list and detaches from the socket by restoring its proto and socket callbacks. If userspace closes the soc...

CVE-2026-45928

CVE-2026-45928 relates to the Linux kernel media driver (chips-media wave5). In wave5_vpu_open_enc() and wave5_vpu_open_dec(), a vpu instance is kzalloc()-ed; if the subsequent allocation for inst->codec_info fails, the error path returns -ENOMEM without freeing the previously allocated vpu, c...

CVE-2026-45944

CVE-2026-45944 affects the Linux kernel IOMMU VT-d.

CVE-2026-46288

CVE-2026-46288 (Linux kernel). The issue is a use-after-free in unittest changeset handling of device-tree nodes: a pointer (parent) shares the same struct device_node as nchangeset, and of_node_put(nchangeset) can drop the refcount to zero while code still uses parent to inspect properties, lead...

CVE-2026-46290

The CVE-2026-46290 issue in Linux kernels’ x86 EFI runtime handling was fixed by replacing in_interrupt() with !in_task() to preserve interrupt/NMI fault handling without being affected by the FPU softirq path. Root cause: kernel_fpu_begin() uses fpregs_lock() with local_bh_disable(), setting SOF...

CVE-2026-46295

CVE-2026-46295 involves the Linux kernel KVM/x86 interrupt handling fix. The patch ensures IRR is scanned via __kvm_apic_update_irr even when PIR is empty, falling back to apic_find_highest_vector() when PID.ON is set but PIR is empty, so the highest pending interrupt is reported from the existin...

CVE-2026-46305

CVE-2026-46305 affects the Linux kernel, specifically the staging/rtl8723bs path. The issue arises when kzalloc_flex()’s return value is used without checking for allocation failure, leading to a potential NULL pointer dereference when accessing the allocated structure.
