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，以下漏洞已得到修复： vdpa/mlx5：修复 add_direct_chain 错误路径中遍历了错误的列表 在 add_direct_chain() 函数中，新分配的 direct MR 条目会被添加到局部列表 'tmp' 中，并且仅在成功时才会将该列表合并（splice）到 mr->head 中。然而，在错误处理路径中，清理循环错误地遍历了 mr->head，而不是正确的局部列表 tmp。 修复方法是在 err_alloc 清理路径中遍历 'tmp' 列表。

Vulnerability Title
vdpa/mlx5: fix wrong list iterated in add_direct_chain error path
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
vdpa/mlx5: fix wrong list iterated in add_direct_chain error path
In add_direct_chain(), newly allocated direct MR entries are added to
the local list 'tmp', which is spliced into mr->head only on success.
On the error path, the cleanup loop was incorrectly iterating over
mr->head instead of tmp.
Fix by iterating over 'tmp' in the err_alloc cleanup path.
