In the Linux kernel, the following vulnerability has been resolved: HID: core: remove unnecessary WARN_ON() in implement() Syzkaller hit a warning [1] in a call to implement() when trying to write a value into a field of smaller size in an output report. Since implement() already has a warn message printed out with the help of hid_warn() and value in question gets trimmed with: ... value &= m; ... WARN_ON may be considered superfluous. Remove it to suppress future syzkaller triggers.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: HID: núcleo: eliminar WARN_ON() innecesario en implementar() Syzkaller recibió una advertencia [1] en una llamada a implementar() al intentar escribir un valor en un campo de tamaño más pequeño. tamaño en un informe de salida. Dado que implement() ya tiene un mensaje de advertencia impreso con la ayuda de hid_warn() y el valor en cuestión se recorta con: ... value &= m; ... WARN_ON puede considerarse superfluo. Elimínelo para suprimir futuros desencadenantes de syzkaller.
