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-2026-68441

The CVE-2026-68441 issue affects the Linux kernel net/sched path where TC_ACT_REDIRECT from qdisc filter chains could be lost and the packet redirected was silently dropped instead of being redirected. A fix adds a tcf_classify_qdisc() inline helper wrapping tcf_classify() to convert a TC_ACT_RED...

CVE-2026-68439

The CVE affects the Linux kernel wifi stack, specifically the mt76/mt7925 components. A NULL-pointer dereference could occur in mt7925_mcu_bss_he_tlv() when mt76_connac_get_he_phy_cap may return NULL, and code dereferences the cap pointer without null-checking. The description notes that a fix ha...
