A deadlock vulnerability in the Linux kernel's enetc network driver was resolved. The issue occurs due to recursive acquisition of the enetc_mdio_lock read lock, leading to thread hangs on the LS1028A platform with RT kernels after a specific workaround was applied. The deadlock arises when a higher-priority writer waits on the lock while readers attempt recursive acquisition, causing a hang. The fix prevents recursive lock acquisition to avoid the deadlock.
