In the Linux kernel, the following vulnerability has been resolved:
pdscore: fix debugfslookup dentry leak and error handling
debugfs_lookup() returns a dentry with an elevated reference count that must be released with dput(). The current code discards the returned dentry without calling dput(), causing a reference leak on every firmware reset recovery.
Additionally, when CONFIGDEBUGFS is disabled, debugfslookup() returns ERRPTR(-ENODEV), not NULL. The current check passes for error pointers and would call dput() on an invalid pointer, causing a crash.
