CVE-2021-26341

Name of the Vulnerable Software and Affected Versions AMD CPUs (affected versions not specified)

Description The issue is related to speculative execution in AMD CPUs, which may allow data leakage by transiently executing beyond unconditional direct branches. This could potentially lead to the disclosure of arbitrary memory areas. For example, a proof-of-concept exploit has been developed to determine address layouts and bypass the KASLR (kernel address space layout randomization) protection mechanism by executing non-privileged code in the ePBF kernel subsystem. Other attack scenarios may also lead to kernel memory content leakage.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
