This update for openssl-3-livepatches fixes the following issues: - HollowByte: DoS vector against OpenSSL TLS ClientHello via remote, attacker-controlled memory allocations bsc1271712, bsc1271713...

CVE-2026-74728

A flaw was found in the Linux kernel's XFS filesystem. When the system attempts to allocate memory for an XFS buffer and that allocation fails, the xfsbuffree function is called with a null buffer address. This leads to a null pointer dereference, causing the kernel to crash. This vulnerability c...

libgit2: libgit2: Denial of Service via Unbounded Memory Allocation

A flaw was found in libgit2. The gitdeltaapply function incorrectly trusts an attacker-controlled size value from a delta object header, which is used for memory allocation before proper validation of delta instructions. A remote attacker or local user can supply malicious pack data, for example,...
