CyberRota Analysis
AI-GeneratedA vulnerability in the Linux kernel affects the GPIO subsystem, specifically related to shared GPIO entries, where a deadlock can occur during the removal of a shared GPIO proxy's parent due to an improperly scoped mutex. This flaw can lead to system instability and potential denial of service if exploited. Linux system administrators and developers working with GPIO configurations should prioritize applying the relevant patches to mitigate this risk.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: gpio: shared: fix deadlock on shared proxy's parent removal Commit 710abda58055 ("gpio: shared: call gpio_chip::of_xlate() if set") used the mutex embedded in struct gpio_shared_entry to protect the offset field which now can be modified after assignment. The critical section however is too wide and introduced a potential deadlock on the removal of the shared GPIO proxy's parent. Make the critical section shorter - only protect the offset when it's being read. While at it: mention the fact that the entry lock is now also used to protect against concurrent access to the offset field in the structure's documentation.
