CVE-2026-52918

The CVE-2026-52918 entry concerns a race in the Linux kernel Bluetooth subsystem. Specifically, bt_sock_poll() traverses the accept_q without proper synchronization, allowing a race between normal polling and child socket teardown which can drop the last reference on the same socket. The advisory...
