CVE-2024-57875

Kernel crash via unprotected zoned-disk bitmap replacement

Published Jan 11, 2025 · Updated Aug 5, 2026

Use-after-free in Linux 6.10 through 6.12.4 allows local users to crash the kernel during zoned-disk revalidation. The disk_zone_is_conv() helper reads disk->conv_zones_bitmap without RCU protection while revalidation can replace and free that bitmap. Triggering requires local low-privileged access, a zoned block device, and a race between bitmap revalidation and a concurrent zone check.
