Report: CVE-2026-31673 - af_unix: read UNIX_DIAG_VFS data under unix_state_lock
CVE ID :CVE-2026-31673 Published : April 25, 2026, 9:16 a.m. | 1 hour, 11 minutes ago Description :In the Linux kernel, the following vulnerability has been resolved: af_unix: read UNIX_DIAG_VFS data under unix_state_lock Exact UNIX diag lookups hold a reference to the socket, but not to u->path. Meanwhile, unix_release_sock() clears u->path under unix_state_lock() and drops the path reference after unlocking. Read the inode and device numbers for UNIX_DIAG_VFS while holding unix_state_lock(), then emit the netlink attribute after dropping the lock. This keeps the VFS data stable while the reply is being built. Severity: 0.0 | NA Visit the link for more details, such as CVSS details, affected products, timeline, and more...
