CVE-2026-80721 - Bluetooth: ISO: ensure no dangling hcon references in iso_conn

CVE ID :CVE-2026-80721
Published : Aug. 28, 2026, 8:16 a.m. | 2 hours, 13 minutes ago
Description :In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: ensure no dangling hcon references in iso_conn After iso_conn_del(), ISO sockets should not dereference the hcon any more. Currently, clearing iso_conn::hcon relies on iso_conn_del() releasing the last reference to the iso_conn. Simplify this by explicitly clearing conn->hcon in iso_conn_del(), to avoid more complex reasoning on races about who holds the last reference.
Severity: 0.0 | NA
