CyberRota Analysis
AI-GeneratedThe vulnerability affects the Linux kernel's NTFS mapping-pairs parser, which improperly handles signed integer overflows when accumulating relative Logical Cluster Numbers (LCNs). This flaw can lead to the corruption of runlists, potentially allowing an attacker to manipulate physical cluster mappings, resulting in data integrity issues. Organizations using Linux systems that handle NTFS file systems should prioritize addressing this vulnerability to mitigate risks related to data corruption and unauthorized access.
Original NVD Description
In the Linux kernel, the following vulnerability has been resolved: ntfs: detect mapping-pairs LCN accumulator overflow The NTFS mapping-pairs parser accumulates relative LCN deltas in a signed integer. A corrupted attribute can drive that addition past the representable range. One corrupt runlist shape sets the accumulated LCN to S64_MAX and then adds a delta of 1 in the next mapping-pairs entry. Signed overflow is undefined and can turn an invalid runlist into a different set of physical clusters. Check the LCN addition for overflow before storing the next run.
