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...
