CVE-2024-46868 Details
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.
A deadlock vulnerability has been identified in the Linux kernel's handling of Qualcomm UEFI Secure Application firmware. This issue arises in the 'qcuefi_acquire' function, where a lock is held if the '__qcuefi' pointer is not set. This can lead to a deadlock if an attempt is made to set the pointer later. The vulnerability affects the Linux kernel stable tree.
Users can upgrade to the latest version of the Linux kernel stable tree to address this vulnerability.
