In the Linux kernel, the following vulnerability has been resolved:
pinctrl: fix deadlock in createpinctrl() when handling -EPROBEDEFER
In createpinctrl(), pinctrlmapsmutex is acquired before calling addsetting(). If addsetting() returns -EPROBEDEFER, createpinctrl() calls pinctrlfree(). However, pinctrlfree() attempts to acquire pinctrlmapsmutex, which is already held by createpinctrl(), leading to a potential deadlock.
This patch resolves the issue by releasing pinctrlmapsmutex before calling pinctrl_free(), preventing the deadlock.
This bug was discovered and resolved using Coverity Static Analysis Security Testing (SAST) by Synopsys, Inc.
