MEDIUM

Linux Kernel 6.7-6.10.11 - Deadlock via Improper Locking in qcuefi_acquire()

Title source: llm

Description

In the Linux kernel, the following vulnerability has been resolved: firmware: qcom: uefisecapp: Fix deadlock in qcuefi_acquire() If the __qcuefi pointer is not set, then in the original code, we would hold onto the lock. That means that if we tried to set it later, then it would cause a deadlock. Drop the lock on the error path. That's what all the callers are expecting.
