In the Linux kernel, the following vulnerability has been resolved:
net: wan: fsl_qmc_hdlc: Convert carrier_lock spinlock to a mutex
The carrier_lock spinlock protects the carrier detection. While it is
held, framer_get_status() is called which in turn takes a mutex.
This is not correct and can lead to a deadlock.
A run with PROVE_LOCKING enabled detected the issue:
[ BUG: Invalid wait context ]
