Description (CNA)
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.
