CVE-2026-68188

A flaw was found in the Linux kernel's Bluetooth RFCOMM subsystem. A race condition in the rfcommttysettermios function allows a session to be freed while it is still actively in use. This use-after-free UAF vulnerability can be exploited by a local attacker. Successful exploitation leads to a...
