CVE-2026-89551

CVE-2026-89551 is a CRITICAL (CVSS 9.8) integer underflow in the Linux kernel's SUNRPC subsystem. The xdr_buf_trim() function subtracts consumed bytes from buf->len without clamping, so when called from gss_krb5_unwrap_v2() with a small wire-derived buf->len while page-scale iov_lens are pr...

CVE-2026-80978

CVE-2026-80978 affects the Linux kernel networking subsystem, specifically the IP tunnel devices. When a local attacker stacks user-created IP tunnel devices, the derived needed_headroom can exceed the 16-bit skb header offset range, causing those offsets to wrap during skb head expansion. The fi...
