In the Linux kernel, the following vulnerability has been resolved: kobject_uevent: Fix OOB access within zap_modalias_env() zap_modalias_env() wrongly calculates size of memory block to move, so will cause OOB memory access issue if variable MODALIAS is not the last one within its @env parameter, fixed by correcting size to memmove.
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: kobject_uevent: corrige el acceso OOB dentro de zap_modalias_env() zap_modalias_env() calcula incorrectamente el tamaño del bloque de memoria a mover, por lo que causará un problema de acceso a la memoria OOB si la variable MODALIAS no es la última dentro de su Parámetro @env, corregido corrigiendo el tamaño a memmove.
