  3. CVE-2023-52764
In the Linux kernel, the following vulnerability has been resolved: media: gspca: cpia1: shift-out-of-bounds in set_flicker Syzkaller reported the following issue: UBSAN: shift-out-of-bounds in drivers/media/usb/gspca/cpia1.c:1031:27 shift exponent 245 is too large for 32-bit type 'int' When the value of the variable "sd->params.exposure.gain" exceeds the number of bits in an integer, a shift-out-of-bounds error is reported. It is triggered because the variable "currentexp" cannot be left-shifted by more than the number of bits in an integer. In order to avoid invalid range during left-shift, the conditional expression is added.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: media: gspca: cpia1: desplazamiento fuera de los límites en set_flicker. Syzkaller informó el siguiente problema: UBSAN: desplazamiento fuera de los límites en drivers/media/usb/gspca /cpia1.c:1031:27 el exponente de desplazamiento 245 es demasiado grande para el tipo 'int' de 32 bits. Cuando el valor de la variable "sd->params.exposure.gain" excede el número de bits en un número entero, se realiza un desplazamiento. Se informa un error fuera de los límites. Se activa porque la variable "currentexp" no puede desplazarse hacia la izquierda más que el número de bits de un número entero. Para evitar un rango no válido durante el desplazamiento a la izquierda, se agrega la expresión condicional.
