A deadlock vulnerability in the Linux kernel's pinctrl subsystem for the meson amlogic-a4 platform was fixed. The issue occurred when accessing the pinconf-pins sysfs node, where a mutex was acquired twice leading to a deadlock. This was resolved by changing the code to avoid re-acquiring the mutex. The vulnerability affects multiple versions of the linux-hwe-edge kernel prior to specific 7.0.0 series builds. A patch is available and included in official Ubuntu kernel updates.
