CVE-2024-27059

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: USB: almacenamiento-usb: evita el error de división por 0 en isd200_ata_command El subcontrolador isd200 en almacenamiento-usb utiliza los valores HEADS y SECTORES en la información de ID de ATA para calcular el cilindro y valores principales al crear un CDB para comandos LEER o ESCRIBIR. El cálculo implica operaciones de división y módulo, lo que provocará un bloqueo si cualquiera de estos valores es 0. Si bien esto nunca sucede con un dispositivo genuino, podría suceder con una emulación defectuosa o subversiva, según lo informado por syzbot fuzzer. Protéjase contra esta posibilidad negándose a vincularse al dispositivo si el valor ATA_ID_HEADS o ATA_ID_SECTORS en la información de ID del dispositivo es 0. Esto requiere que isd200_Initialization() devuelva un código de error negativo cuando falla la inicialización; actualmente siempre devuelve 0 (incluso cuando hay un error).

In the Linux kernel, the following vulnerability has been resolved: USB: usb-storage: Prevent divide-by-0 error in isd200_ata_command 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. 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).

Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this vulnerability to cause a denial of service. Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition, leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a denial of service.
