php: fatal error handling retains stale request state leading to use-after-free

A flaw was found in PHP's error handling and worker process state management. PHP contains error handling, object, and extension state that is retained by the process but points to memory owned by a single request. A fatal error can interrupt an operation or cleanup phase before that state is...

CVE-2026-99030

The Linux kernel contains a vulnerability in the skb_copy_and_csum_bits() function where unreadable fragments cause the function to return 0 after only copying the linear part. This leaves stale bytes in the caller's buffer, which is then sent over the wire as part of an ICMP error quote or a dri...
