CVE-2024-56570 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. 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.. EPSS estimates a 0.23% chance of exploitation in the next 30 days.
