CVE-2023-53137

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ext4: Fix possible corruption when moving a directory<br /> <br /> When we are renaming a directory to a different directory, we need to<br /> update &amp;#39;..&amp;#39; entry in the moved directory. However nothing prevents moved<br /> directory from being modified and even converted from the inline format<br /> to the normal format. When such race happens the rename code gets<br /> confused and we crash. Fix the problem by locking the moved directory.
