CVE-2024-27059

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command<br /> <br /> The isd200 sub-driver in usb-storage uses the HEADS and SECTORS values<br /> in the ATA ID information to calculate cylinder and head values when<br /> creating a CDB for READ or WRITE commands. The calculation involves<br /> division and modulus operations, which will cause a crash if either of<br /> these values is 0. While this never happens with a genuine device, it<br /> could happen with a flawed or subversive emulation, as reported by the<br /> syzbot fuzzer.<br /> <br /> Protect against this possibility by refusing to bind to the device if<br /> either the ATA_ID_HEADS or ATA_ID_SECTORS value in the device&amp;#39;s ID<br /> information is 0. This requires isd200_Initialization() to return a<br /> negative error code when initialization fails; currently it always<br /> returns 0 (even when there is an error).
