Astra Linux - уязвимость в linux-5.10
In the Linux kernel, the following vulnerability has been resolved: net/tcp: The socket memory leak in TCP-AO failure handling for IPv6 has been fixed. When tcpaocopyallmatching fails in tcpv6synrecvsock, the function simply exits. This results in a memory leak: unreferenced object...
CVE-2026-43384
A flaw was found in the Linux kernel's TCP Authentication Option TCP-AO implementation. This vulnerability arises from a non-constant-time comparison of Message Authentication Codes MACs. A remote attacker could potentially exploit this timing discrepancy to perform a timing attack, which may lea...
