CVE-2026-80980

CVE-2026-80980 is a race condition in the Linux kernel's SMC (Server Message Block over Remote Direct Memory Access) protocol. Three single-bit flags (killed, freed, out_of_sync) in struct smc_connection share a single byte and are written from concurrent contexts—smc_cdc_msg_validate() from a re...

UBUNTU-CVE-2026-72062

In the Linux kernel, the following vulnerability has been resolved: gpio: mt7621: avoid corruption of shared interrupt trigger state The bank-shared fields like 'rising' and 'falling' are modified using non-atomic read-modify-write operations. Since every gpio chip instance represents an entire...

CVE-2026-72062

CVE-2026-72062 affects the Linux kernel GPIO path for mt7621, where bank-wide interrupt-trig state (rising/falling) could be corrupted by non-atomic read-modify-write updates when multiple IRQs on the same bank run concurrently. The issue arises because each gpio chip instance represents a 32-pin...

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-2026-32018 OpenClaw < 2026.2.19 - Race Condition in Sandbox Registry Write Operations

OpenClaw versions prior to 2026.2.19 contain a race condition vulnerability in concurrent updateRegistry and removeRegistryEntry operations for sandbox containers and browsers. Attackers can exploit unsynchronized read-modify-write operations without locking to cause registry updates to lose data...

CVE-2026-23230

CVE-2026-23230 is a Linux kernel local race in the SMB/CIFS client code where cached_fid bitfields (is_open, has_lease, on_list) were updated via concurrent paths, causing read–modify–write races. The root cause is that these three flags shared a single byte, so an update to one could overwrite o...
