Descriptions
In the Linux kernel, the following vulnerability has been resolved:
gpio: wcd934x: Fix shift-out-of-bounds error
bit-mask for pins 0 to 4 is BIT(0) to BIT(4) however we ended up with BIT(n - 1)
which is not right, and this was caught by below usban check
UBSAN: shift-out-of-bounds in drivers/gpio/gpio-wcd934x.c:34:14
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: gpio: wcd934x: corrección de error de desplazamiento fuera de los límites. La máscara de bits para los pines 0 a 4 es BIT(0) a BIT(4); sin embargo, terminamos con BIT( n - 1) lo cual no es correcto, y esto fue detectado por la siguiente verificación USB UBSAN: shift-out-of-bounds in drivers/gpio/gpio-wcd934x.c:34:14
