CVE-2026-80819 Bluetooth: RFCOMM: take rfcomm_mutex for the deferred setup accept

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: RFCOMM: take rfcommmutex for the deferred setup accept rfcommsockrecvmsg completes a deferred setup by calling rfcommdlcaccept without holding any RFCOMM lock: if testandclearbitRFCOMMDEFERSETUP, &d-flags...

CVE-2026-80819

CVE-2026-80819 is a null pointer dereference in the Linux kernel 's Bluetooth RFCOMM subsystem. The flaw occurs when rfcomm_sock_recvmsg() calls rfcomm_dlc_accept() without holding rfcomm_mutex. A remote peer can trigger the bug by sending a DISC frame on a deferred-setup DLC, which clears d->...

CVE-2026-80659

A flaw was found in the Linux kernel's vub300 driver. When the vub300cmndworkthread function holds a command mutex and a command response times out, the device reset path attempts to re-acquire the same mutex recursively. This recursive locking can lead to a deadlock, causing a Denial of Service...
