CVE-2026-98289

In the Linux kernel, the following vulnerability has been resolved: afunix: Unify sccindex when finalising SCC in unixwalkscc. Commit bfdb01283ee8 "afunix: Assign a unique index to SCC." changed Tarjan's algorithm to update lowlink with lowlink, which is called lowpoint unixvertex.sccindex...

CVE-2026-98289

The Linux kernel contains a vulnerability in the af_unix component related to how Tarjan's algorithm handles SCC (Strongly Connected Component) indices. Specifically, the unix_vertex_dead() function assumes all vertices in an SCC share the same lowpoint (scc_index), but this assumption fails if a...
