  "description": "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 ]   ...   c204ddbc (\u0026framer-\u003Emutex){\u002B.\u002B.}-{3:3}, at: framer_get_status\u002B0x40/0x78   other info that might help us debug this:   context-{4:4}   2 locks held by ifconfig/146:   #0: c0926a38 (rtnl_mutex){\u002B.\u002B.}-{3:3}, at: devinet_ioctl\u002B0x12c/0x664   #1: c2006a40 (\u0026qmc_hdlc-\u003Ecarrier_lock){....}-{2:2}, at: qmc_hdlc_framer_set_carrier\u002B0x30/0x98  Avoid the spinlock usage and convert carrier_lock to a mutex.",
