XFS Filesystem Bitmap Error Handling Flaw

Publication date: 2026-09-25

Last updated on: 2026-09-25

Assigner: kernel.org

Description
In the Linux kernel, the following vulnerability has been resolved: xfs: bail out on bitmap errors in xrep_agfl_fill LOLLM also points out that the xagb_bitmap_set call in xrep_agfl_fill can fail, but we don't check the result of xagb_bitmap_walk, so we silently drop the error and proceed with inconsistent incore data. That shouldn't be allowed.

Executive Summary

This vulnerability is in the Linux kernel's XFS file system. It occurs in the xrep_agfl_fill function where an error in setting a bitmap (xagb_bitmap_set) is not properly checked. The system continues processing despite the error, leading to inconsistent in-memory data which could cause further issues.

Impact Analysis

This vulnerability could lead to data corruption or system crashes in systems using the XFS file system. If the bitmap error occurs, the kernel may operate with incorrect data, potentially causing file system inconsistencies or failures.

Mitigation Strategies

Update the Linux kernel to the latest patched version to resolve the xfs bitmap error in xrep_agfl_fill. Monitor kernel logs for filesystem errors related to XFS operations.
