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： xfs: 在添加目录路径失败时销毁已见 inode 位图 LOLLM 在 中观察到一处内存泄漏：当创建目录路径对象成功，但将名称追加到路径中失败时，就会发生此问题。出现该情况时，系统未释放（空的）已见 inode 位图。这是一个较为简单的错误，但我们不应留下逻辑炸弹。 对 中类似的缺陷也执行相同的修复。

Vulnerability Title
xfs: destroy seen inode bitmap when we fail to add a dirpath
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
xfs: destroy seen inode bitmap when we fail to add a dirpath
LOLLM observes a memory leak in xchk_dirtree_create_path if we create
the directory path object but appending the name to the path fails.
When this happens, we don't tear down the (empty) seen inode bitmap.
This is a pretty trivial error, but let's not leave logic bombs.
Do the same for a similar bug in xrep_dirtree_create_adoption_path.
