- CVE-2025-40200 affecting package kernel for versions less than 6.6.117.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
Squashfs: reject negative file sizes in squashfsreadinode()
Syskaller reports a "WARNING in ovlcopyup_file" in overlayfs.
This warning is ultimately caused because the underlying Squashfs file system returns a file with a negative file size.
This commit checks for a negative file size and returns EINVAL.
