CVE-2024-27389: Linux Kernel

Medium severity, CVSS 5.5. EPSS: 0.2% chance of exploitation in the next 30 days.

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. ---

Affected products

• Linux Linux Kernel: from 5.8, before 6.1.83 (fixed in 6.1.83); from 6.2, before 6.6.23 (fixed in 6.6.23); from 6.7, before 6.7.11 (fixed in 6.7.11); from 6.8, before 6.8.2 (fixed in 6.8.2)
