CVE-2026-12233 Uninitialized mutex in TLS trusted-credential backend causes kernel NULL-deref DoS under contention

The PSA Protected Storage credential backend subsys/net/lib/tlscredentials/tlscredentialstrusted.c declared its credential-store mutex as a plain zero-filled static struct kmutex credentiallock; and never called kmutexinit on it. A statically zero-filled kmutex has an uninitialized wait queue its...

CVE-2026-12233

CVE-2026-12233 affects the PSA Protected Storage TLS credential backend. The credential_store mutex was declared as a zero-initialized static k_mutex and never initialized, leaving its wait queue NULL. Under contention, z_pend_curr() appends to this uninitialized wait queue and dereferences a NUL...

CVE-2026-68132

A flaw was found in the Linux kernel. A deadlock can occur during the emergency thaw process of frozen block devices. This issue arises when the dothawallcallback function attempts to reacquire a lock it already holds exclusively, while also holding another mutex. This deadlock prevents further...

CVE-2026-68179

A flaw was found in the Linux kernel's Network Shared Memory NSM module. A local attacker can exploit an issue in the nsmdevioctl function where an incorrect mutex unlock operation is performed. This occurs when an initial data copy fails, leading to an attempt to unlock a mutex that was never...
