CVE-2026-31631

The CVE-2026-31631 issue concerns the Linux kernel’s rxrpc path, specifically a buffer overread in rxgk_do_verify_authenticator(). The vulnerability arises because the function checks the nonce before validating the buffer size, potentially reading beyond the allocated memory. A fix has been appl...

CVE-2026-31630

The CVE-2026-31630 issue affects the Linux kernel RXRPC procfs address formatting: AF_RXRPC procfs helpers used fixed 50-byte buffers to render local/remote socket addresses with "%pISpc", which is insufficient for the longest current IPv6-with-port forms (notably ISATAP paths). The root cause is...
