USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command
CWE ID: N/A
Base Score (CVSS): N/A
CVE: CVE-2024-27059
Descrizione: In the Linux kernel, the following vulnerability has been fixed: USB: usb-storage: Prevent divide-by-zero error in isd200_ata_command The isd200 sub-driver in usb-storage uses HEADS and SECTORS values in the ATA ID information to calculate cylinder and head values when creating a CDB for READ or WRITE commands. The calculation involves division and modulus operations, which will cause a crash if either of these values is 0. While this never happens with a genuine device, it could happen with a flawed or subversive emulation, as reported by the syzbot fuzzer. Protect against this possibility by refusing to bind to the device if either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device’s ID information is 0. This requires isd200_Initialization() to return a negative error code when initialization fails; currently it always returns 0 (even when there is an error).
