Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

Linux kernel是美国Linux基金会开源的一个操作系统内核。 Linux kernel 7.1.5之前版本存在安全漏洞，该漏洞源于NTFS mapping-pairs解析器在累加相对LCN增量时未检查整数溢出，可能导致有符号整数溢出，从而将无效运行列表转换为不同的物理集群集合。

Vulnerability Title
ntfs: detect mapping-pairs LCN accumulator overflow
Source: CVE Program / CVE List V5
Vulnerability 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.
