Picotls is a TLS protocol library that allows users select different crypto backends based on their use case. Picotls implements its own ASN.1 validation helper, which is used by the minicrypto backend while parsing local PKCS8 private keys. Prior to commit c14231d801407640bc42c2dcf92783409ea6a7c...

CVE-2026-74576

A flaw was found in the Linux kernel's memory management. This vulnerability allows for unbounded recursion in the slab free path, a process where the kernel manages and releases small blocks of memory. When certain kernel memory allocation caches kmalloc caches form a cycle during internal data...
