CVE-2024-42094 Information

Description

In the Linux kernel the following vulnerability has been resolved:

net/iucv: Avoid explicit cpumask var allocation on stack

For CONFIG_CPUMASK_OFFSTACK=y kernel explicit allocation of cpumask variable on stack is not recommended since it can cause potential stack overflow.

Instead kernel code should always use cpumask_var API(s) to allocate cpumask var in config-neutral way leaving allocation strategy to CONFIG_CPUMASK_OFFSTACK.

Use cpumask_var API(s) to address it.
