CVE-2024-42305

A flaw was found in the Linux kernel's ext4 filesystem. When converting a directory to an indexed format, the system incorrectly assumes the presence of "dot" and "dotdot" entries. A local attacker could create a specially crafted filesystem image that, when processed during a rename operation, triggers an out-of-bounds access. This vulnerability can lead to a system crash, resulting in a Denial of Service (DoS).
