CVE-2026-43255

The CVE-2026-43255 entry concerns the Linux kernel component for wireless Libertus (wifi: libertas). The vulnerability arises when usb_tx_block() submits cardp->tx_urb without guaranteeing the previous URB has completed; a second call during active URB state can trigger a warning (“URB submitt...

CVE-2026-43287

The CVE targets Linux kernel DRM:MODE_CREATEPROPBLOB allocations. Arbitary-sized property blobs allocated for kernel memory were not charged to the caller’s memory cgroup, enabling unprivileged local users to trigger unbounded kernel memory growth and potential system-wide OOM. The fix ensures bl...

CVE-2026-43295

The CVE-2026-43295 entry concerns the Linux kernel rapidio subsystem. A memory-management bug in rio_scan_alloc_net() uses rio_free_net() instead of kfree() when idtab allocation fails, leaving the net object potentially unreleased.

The fix uses the driver-core driver_override infrastructure to en...

CVE-2026-53138

The CVE-2026-53138 issue affects the Linux kernel’s drm/amd/display driver. A malformed VBIOS image can cause unbounded record-chain walk loops in bios_parser.c and bios_parser2.c due to for(;;) loops that terminate only on a 0xFF sentinel or zero record_size. This can lead to a large number of i...

CVE-2026-53140

The CVE-2026-53140 issue pertains to the Linux kernel drm/v3d driver. A fault in v3d_rewrite_csd_job_wg_counts_from_indirect() maps both the indirect buffer and the workgroup buffer and, if any workgroup count read from the buffer is zero, the cleanup is skipped on an early exit, leaking the virt...

CVE-2026-53169

In the Linux kernel, accel/ethosu has been fixed to reject NPU_OP_RESIZE commands from userspace. The driver previously used an unconditional WARN_ON(1) in DRM_IOCTL_ETHOSU_GEM_CREATE, enabling kernel log spam and, if panic_on_warn was set, potential DoS via a local unprivileged user.
