Descriptions
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.
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.
An out-of-bounds write flaw was found in the Linux kernel's multiq qdisc functionality. This vulnerability allows a local user to crash or potentially escalate their privileges on the system.
