CVE-2026-80702

CVE-2026-80702 is a use-after-corruption flaw in the Linux kernel's vmwgfx DRM driver (vmwgfx_resource.c). Two code paths (vmw_resource_release() and vmw_resource_unbind_list()) erroneously assign boolean literals (0 or 1) to the guest_memory_size field—an unsigned long allocation-size field—inst...

CVE-2026-68387

The CVE-2026-68387 defect affects the Linux kernel CAN raw socket path. A change to store flags in a single bitfield (struct raw_sock) introduced a read-modify-write window during raw_setsockopt() flag updates, enabling concurrent access races. The fix adds a locking wrapper around flag manipulat...

CVE-2026-68387 can: raw: add locking for raw flags bitfield

In the Linux kernel, the following vulnerability has been resolved: can: raw: add locking for raw flags bitfield With commit 890e5198a6e5 "can: raw: use bitfields to store flags in struct rawsock" the formerly separate integer values have been integrated into a single bitfield. This led to a...

CVE-2026-68316

The CVE affects the Linux kernel accel: ethosu component. Two issues in command stream validation lead to undercounted element sizes for 16/32/64-bit elements and, for NHWC format, missing element size in the calculation. The element-size bitfield differs between IFM/IFM2 (bits 2:3) and OFM (bits...
