Published: 2024-06-19 | Last Modified: 2026-08-04 | Status: Modified

Description

In the Linux kernel, the following vulnerability has been resolved: net: sched: sch_multiq: fix possible OOB write in multiq_tune() q->bands will be assigned to qopt->bands to execute subsequent code logic after kmalloc. So the old q->bands should not be used in kmalloc. Otherwise, an out-of-bounds write will occur.

Additional Descriptions (1)

En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: net: sched: sch_multiq: corrige posible escritura OOB en multiq_tune() q->bands se asignarán a qopt->bands para ejecutar la lógica de código posterior después de kmalloc. Por lo tanto, las antiguas q->bands no deberían usarse en kmalloc. De lo contrario, se producirá una escritura fuera de los límites.
