CVE-2024-27059

Kernel crash via zero ATA geometry

Published May 1, 2024 · Updated May 12, 2026

Divide-by-zero in the Linux kernel USB isd200 storage driver allows local users to crash the system with a subversive emulated device. isd200_ata_command divides and takes a modulus by ATA ID HEADS and SECTORS values without first rejecting zero values. Exploitation requires presenting crafted ATA identity data while the driver binds the emulated storage device; the resulting impact is a kernel crash.
