CVE-2024-56570
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.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.24%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
