NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-libbpf-devel package and not the kernel-libbpf-devel package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2023 relevant fixed versions and status.

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

ovl: Filter invalid inodes with missing lookup function

Add a check to the ovl_dentry_weird() function to prevent the processing of directory inodes that lack the lookup function. This is important because such inodes can cause errors in overlayfs when passed to the lowerstack.
