CVE-2023-53055
|
| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
fscrypt: destroy keyring after security_sb_delete()
fscrypt_destroy_keyring() must be called after all potentially-encrypted
inodes were evicted; otherwise it cannot safely destroy the keyring.
Since inodes that are in-use by the Landlock LSM don't get evicted until
security_sb_delete(), this means that fscrypt_destroy_keyring() must be
called *after* security_sb_delete().
This fixes a WARN_ON followed by a NULL dereference, only possible if
Landlock was being used on encrypted files. |
