CVE-2026-23126

CVE-2026-23126 affects the Linux kernel netdevsim driver. It describes a race on the bpf_bound_progs list between nsim_bpf_create_prog() (list_add_tail) and nsim_bpf_destroy_prog() (list_del), which can corrupt the list and trigger a kernel crash (kernel BUG at lib/list_debug.c). The proposed rem...

kernel: net/mlx5e: Check for NOT_READY flag state after locking

A race condition was found in the Linux kernel Mellanox mlx5 network driver's traffic control offload flow management. A local user with privileges to configure traffic control flower filters can trigger concurrent flow deletion operations where the NOTREADY flag is checked before acquiring the...

kernel: drm/i915: Fix NULL ptr deref by checking new_crtc_state

A NULL pointer dereference vulnerability was found in the Intel i915 graphics driver in the Linux kernel. The intelatomicgetnewcrtcstate function can return NULL if the CRTC state was not previously obtained via intelatomicgetcrtcstate, but the return value was not checked before use. This leads ...
