Description

In the Linux kernel, the following vulnerability has been resolved:  nfc: hci: shdlc: Stop timers and work before freeing context  llc_shdlc_deinit() purges SHDLC skb queues and frees the llc_shdlc structure while its timers and state machine work may still be active.  Timer callbacks can schedule sm_work, and sm_work accesses SHDLC state and the skb queues. If teardown happens in parallel with a queued/running work item, it can lead to UAF and other shutdown races.  Stop all SHDLC timers and cancel sm_work synchronously before purging the queues and freeing the context.  Found by Linux Verification Center (linuxtesting.org) with SVACE.
