CVE-2026-64024
A flaw was found in the Linux kernel's Transmission Control Protocol TCP networking stack. This vulnerability arises from a stale per-CPU variable that can retain a previously used Initial Sequence Number ISN when certain packets are dropped. A remote attacker could exploit this by sending...

CVE-2026-64024
CVE-2026-64024 concerns a Linux kernel issue where a per-CPU tcp_tw_isn leak could enable ISN prediction. The root cause was that TIME_WAIT-derived ISNs were stored in a per-CPU variable and could be consumed by a subsequent SYN if a packet was dropped along several paths (e.g., min_ttl/min_hop, ...
PT-2026-61341
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the TCP implementation where a stale per-CPU tcp tw isn variable can leak, enabling Initial Sequence Number ISN prediction. The issue occurs because the system assumes t...
