CVE-2026-46329 Details
Description
In the Linux kernel, the following vulnerability has been resolved: erofs: handle end of filesystem properly for file-backed mounts I/O requests beyond the end of the filesystem should be zeroed out, similar to loopback devices and that is what we expect.
A vulnerability in the Linux kernel's EROFS (Enhanced Read-Only File System) implementation has been addressed. The issue involved improper handling of file-backed mounts at the end of the filesystem. I/O requests extending beyond the filesystem's limits were not being zeroed out as expected, similar to the behavior of loopback devices. This vulnerability could potentially lead to unintended data exposure or corruption.
Users can upgrade to the latest version of the Linux kernel where this vulnerability has been fixed. Instructions for downloading the patched version can be found in the Linux kernel documentation.
