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，已修复以下漏洞： ksmbd：传播 DACL 解析错误 函数会静默接受截断的访问控制条目（ACEs）以及内存分配失败的情况，导致 能够基于不完整的 ACL 转换继续执行。 现将解析错误和分配错误返回给 ，以便在更新 inode 属性或 ACL 扩展属性（xattrs）之前，拒绝格式错误的描述符。

Vulnerability Title
ksmbd: propagate DACL parsing errors
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved: ksmbd: propagate DACL parsing errors parse_dacl() silently accepts truncated ACEs and allocation failures, allowing set_info_sec() to continue with an incomplete ACL conversion. Return parsing and allocation errors to parse_sec_desc() so malformed security descriptors are rejected before inode attributes or ACL xattrs are updated.
