CVE-2024-46777

Name of the Vulnerable Software and Affected Versions Linux kernel versions prior to 6.6.52

Description The issue concerns the Linux kernel, where a vulnerability has been resolved related to the udf filesystem. The problem arises when mounting filesystems where the partition would overflow the 32-bits used for block number, or when the partition length is so large that it cannot safely index bits in a block bitmap.

Recommendations Update to Linux kernel version 6.6.52 or later to resolve the issue. As a temporary workaround, consider avoiding the mounting of filesystems with excessively large partition lengths until a patch is available. Restrict access to the udf filesystem to minimize the risk of exploitation.
