Description

The vulnerability allows a remote attacker to gain access to sensitive information on the target system.

The vulnerability exists due to the implementations of EAP-PWD are vulnerable to side-channel attacks as a result of cache access patterns. A remote attacker with ability to install and execute applications can crack weak passwords when memory access patterns are visible in a shared cache.

Note, this vulnerability exists due to incomplete fix for #VU23960 (CVE-2019-9495).
