  "description": "In the Linux kernel, the following vulnerability has been resolved:  gpio: shared: fix deadlock on shared proxy\u0027s parent removal  Commit 710abda58055 (\u0022gpio: shared: call gpio_chip::of_xlate() if set\u0022) 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\u0027s parent.  Make the critical section shorter - only protect the offset when it\u0027s 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\u0027s documentation.",
