Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the af unix module where the unix vertex dead function incorrectly assumes all vertices in a Strongly Connected Component SCC share the same lowpoint, represented by t...
CVE-2026-80521
In the Linux kernel, the following vulnerability has been resolved: afunix: Unlink sccentry in unixdeledge. Kyle Zeng reported that GC could free a dead SCC partially. The scenario is as follows: 1 Create two SCCs: X -. A B ^--' 2 Run the following concurrently: 2-1 send sk-B to sk-B from sk-X 2-...
CVE-2026-80521
CVE-2026-80521 is a use-after-free in the Linux kernel's af_unix subsystem, specifically in the garbage collection (GC) logic for strongly connected components (SCC). A race in unix_del_edge() allows the GC to free a dead SCC partially when a concurrent send() of a socket and close() of other soc...

LSN-0118-1: Kernel Live Patch Security Notice
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix UAF in async decryption Doing an async decryption large read crashes with a slab-use-after-free way down in the crypto API. In the Linux kernel, the following vulnerability has been resolved: padata: avoid UAF fo...
Linux kernel __unix_walk_scc() Heap Buffer Overflow
The vulnerability of the unixwalkscc function in the net/unix/garbage.c module, which is part of the Linux kernel’s networking functions, stems from the lack of initialization for a variable. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...
