Linux Kernel LoongArch KVM Array Index Overflow Vulnerability

Vulnerability

An array index overflow vulnerability has been identified in the Linux kernel's KVM component for LoongArch architecture. The issue arises because the variable 'index' is modified and reused as an array index when handling the 'EIOINTC_ENABLE' register, leading to the potential for an overflow.

Impact

Exploitation of this vulnerability could result in an array index overflow, which may lead to memory corruption or other unintended behavior.
