How to fix?

Upgrade SLES:16.0.0 kernel-docs-html to version 6.12.0-160000.26.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-docs-html package and not the kernel-docs-html package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

md/raid5: fix possible null-pointer dereferences in raid5_store_group_thread_cnt()

The variable mddev->private is first assigned to conf and then checked:

conf = mddev->private; if (!conf) ...

If conf is NULL, then mddev->private is also NULL. In this case, null-pointer dereferences can occur when calling raid5_quiesce():

raid5_quiesce(mddev, true); raid5_quiesce(mddev, false);

since mddev->private is assigned to conf again in raid5_quiesce(), and conf is dereferenced in several places, for example:

conf->quiesce = 0; wake_up(&conf->wait_for_quiescent);

To fix this issue, the function should unlock mddev and return before invoking raid5_quiesce() when conf is NULL, following the existing pattern in raid5_change_consistency_policy().
