Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: netfilter: conntrack: tcp: Do not force the CLOSE state on an invalidseqrst packet without checking the direction. An unintended behavior in the TCP conntrack state machine allows a connection to be forced into the CLOSE state...

kernel: netfilter: conntrack: tcp: do not force CLOSE on invalid-seq RST without direction check

A flaw was found in the Linux kernel's netfilter conntrack TCP state machine. A remote attacker can exploit this vulnerability by sending a specially crafted sequence of TCP Transmission Control Protocol packets, specifically a SYN synchronize packet followed by an RST reset packet with an invali...

CVE-2026-53368

A flaw was found in the Linux kernel's F2FS Flash-Friendly File System component. A race condition exists where the f2fsneeddentrymark function incorrectly reads natentry flags without proper synchronization during checkpoint operations. This can lead to an inconsistent inode block marking state,...
