EUVD-2026-45719

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: ISO: fix UAF in isorecvframe isorecvframe reads conn-sk under isoconnlock but releases the lock before using sk, with no reference held. A concurrent isosockkill can free sk in that window, causing use-after-free on...

kernel: Bluetooth: SCO: Fix use-after-free in sco_recv_frame() due to missing sock_hold

A flaw was found in the Linux kernel's Bluetooth SCO Synchronous Connection-Oriented protocol implementation. The scorecvframe function fails to properly hold a reference to a socket after releasing a lock. This oversight allows a concurrent operation to free the socket while it is still being...
