| Name | CVE-2022-50377 |
| Description | In the Linux kernel, the following vulnerability has been resolved: ext4: check and assert if marking an no_delete evicting inode dirty In ext4_evict_inode(), if we evicting an inode in the 'no_delete' path, it cannot be raced by another mark_inode_dirty(). If it happens, someone else may accidentally dirty it without holding inode refcount and probably cause use-after-free issues in the writeback procedure. It's indiscoverable and hard to debug, so add an WARN_ON_ONCE() to check and detect this issue in advance. |
