Description
A flaw was found in the Linux kernel's NTFS component. The mapping pairs decoder fails to verify if a run length extends beyond the volume boundary. A local attacker could exploit this by providing a malformed NTFS image with a crafted mapping pairs array. This could lead to memory corruption and potentially allow for privilege escalation.
