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.</p> <p>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&#39;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).</p> <p><strong>Affected:</strong> Linux, Siemens SIMATIC S7-1500 TM MFP - GNU/Linux subsystem</p> <p>In the Linux kernel, the following vulnerability has been resolved:</p> <p>USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command</p> <p>The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values in the ATA ID information to calculate cylinder and head values when creating a CDB for READ or WRITE commands.
