Detailsinfo

A vulnerability has been found in Linux Kernel up to 6.3.2 and classified as critical. This vulnerability affects the function get_max_inline_xattr_value_size of the component ext4. The manipulation with an unknown input leads to a allocation of resources vulnerability. The CWE definition for the vulnerability is CWE-770.

The impact remains unknown. CVE summarizes:

In the Linux kernel, the following vulnerability has been resolved: ext4: add bounds checking in get_max_inline_xattr_value_size() Normally the extended attributes in the inode body would have been checked when the inode is first opened, but if someone is writing to the block device while the file system is mounted, it's possible for the inode table to get corrupted. Add bounds checking to avoid reading beyond the end of allocated memory if this happens.

The advisory is available at git.kernel.org. This vulnerability was named CVE-2023-53285 since 09/16/2025. Technical details are known, but there is no available exploit.
