Quick assessment

Affected
Linux Linux
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.

在 Linux 内核中，已解决以下漏洞： IMA：实例化 file_truncate 和 path_truncate 钩子 为了在截断操作请求发生时立即重置操作缓存标志（IMA_DONE_MASK），需实例化 file_truncate 和 path_truncate 的 LSM 钩子。这样，在后续访问文件时，将依据安全策略重新收集、重新测量、重新审计并重新评估该文件。

Vulnerability Title
ima: Instantiate file_truncate and path_truncate hooks
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ima: Instantiate file_truncate and path_truncate hooks Instantiate the file_truncate and path_truncate LSM hooks to reset the action cache flags (IMA_DONE_MASK) as soon as truncation is requested, so the file, based on policy, is re-collected, re-measured, re-audited, and re-appraised on next access.
