Description
A flaw was found in the Linux kernel's OMFS filesystem. A local attacker could exploit this by providing a specially crafted filesystem image. When processing the image, an integer underflow occurs, leading to an out-of-bounds write that overwrites kernel memory. This could result in a system crash or potentially allow for arbitrary code execution.
