    "summary": "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.",
