PYSEC-2026-2544 kas checks out SHA-like git branches as valid commits

Impact When relying solely on a git commit ID SHA-1 or SHA-256 to qualify if a checkout of a repository is equivalent to the state validated while adding its commit ID to a kas configuration, users may be tricked to check out a branch of the same name from this repository. This implies that the...

kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...
