CVE-2026-97542 PUBLISHED

xfs: bail out on bitmap errors in xrep_agfl_fill

Assigner: Linux
Reserved: 24.09.2026 Published: 25.09.2026 Updated: 25.09.2026

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.
