Descriptions

An issue was discovered in drivers/input/input.c in the Linux kernel before 5.17.10. An attacker can cause a denial of service (panic) because input_set_capability mishandles the situation in which an event code falls outside of a bitmap.

Se descubrió un problema en drivers/input/input.c en el kernel de Linux anterior a la versión 5.17.10. Un atacante puede provocar una denegación de servicio (pánico) porque input_set_capability maneja mal la situación en la que un código de evento queda fuera de un mapa de bits.

A vulnerability was found in drivers/input/input.c in the Linux Kernel, where the input_set_capability() function mishandles scenarios where an event code is outside the bitmap. This issue can lead to a kernel panic when the event code exceeds the bitmap for the specified event type, which could allow an attacker to cause a kernel crash and potential disruption of services.
