CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's handling of NTFS file systems, specifically in the mapping pairs decoder, which fails to verify that the run length does not exceed the volume boundary. An attacker could exploit this flaw using a crafted NTFS image, potentially leading to memory corruption and privilege escalation. Linux system administrators and developers working with NTFS file systems should prioritize addressing this issue to mitigate the risk of exploitation.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: ntfs: verify run length exceeding volume boundary The mapping pairs decoder validates that the starting LCN is within the volume but does not check if the run extends beyond the volume boundary. A malformed NTFS image with a crafted mapping pairs array could cause the kernel to access memory beyond the volume boundary, potentially leading to memory corruption and privilege escalation. Add validation to ensure lcn + length stays within nr_clusters.
