"value": "In the Linux kernel, the following vulnerability has been resolved:\n\npds_core: fix debugfs_lookup dentry leak and error handling\n\ndebugfs_lookup() returns a dentry with an elevated reference count that\nmust be released with dput(). The current code discards the returned\ndentry without calling dput(), causing a reference leak on every\nfirmware reset recovery.\n\nAdditionally, when CONFIG_DEBUG_FS is disabled, debugfs_lookup()\nreturns ERR_PTR(-ENODEV), not NULL. The current check passes for error\npointers and would call dput() on an invalid pointer, causing a crash."
