CVE-2026-68147

Summary: CVE-2026-68147 affects the Linux kernel fscrypt subsystem. When a blk_crypto_key is evicted, the code previously allocated a list of block devices on the heap; allocation failures could lead to premature key free and a use-after-free. The fix switches to an on-stack array to enumerate bl...

CVE-2026-68144

The CVE-2026-68144 issue is in the Linux kernel Phonet subsystem (pep_get_sb). The root cause is use-after-free caused when pep_get_sb() doesn’t account for skb data relocation by pskb_may_pull(), leading to a stale pointer dereference. Reproductions via KASAN show slab-use-after-free in pep_get_...
