CVE-2024-27389  (opens in a new tab)

How to fix?

There is no fixed version for RHEL:9 kernel-modules-partner.

NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-modules-partner package and not the kernel-modules-partner package as distributed by RHEL. See How to fix? for RHEL:9 relevant fixed versions and status.

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

pstore: inode: Only d_invalidate() is needed

Unloading a modular pstore backend with records in pstorefs would trigger the dput() double-drop warning:

WARNING: CPU: 0 PID: 2569 at fs/dcache.c:762 dput.part.0+0x3f3/0x410

Using the combo of d_drop()/dput() (as mentioned in Documentation/filesystems/vfs.rst) isn't the right approach here, and leads to the reference counting problem seen above. Use d_invalidate() and update the code to not bother checking for error codes that can never happen.
