This vulnerability has a CVSS 3.1 base score of 5.5, rated MEDIUM. It requires local or adjacent network access to exploit. Some level of privileges is required for exploitation.

Technical Description

In the Linux kernel, the following vulnerability has been resolved:

LoongArch: Enable IRQ if do_ale() triggered in irq-enabled context

Unaligned access exception can be triggered in irq-enabled context such

as user mode, in this case do_ale() may call get_user() which may cause

sleep. Then we will get:

BUG: sleeping function called from invalid context at arch/loongarch/kernel/access-helper.h:7
