{"id":"CVE-2024-47733","summary":"netfs: Delete subtree of 'fs/netfs' when netfs module exits","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnetfs: Delete subtree of 'fs/netfs' when netfs module exits\n\nIn netfs_init() or fscache_proc_init(), we create dentry under 'fs/netfs',\nbut in netfs_exit(), we only delete the proc entry of 'fs/netfs' without\ndeleting its subtree.
