Summary
It was discovered that improper initialization of CPU cache memory could
allow a local attacker with hypervisor access to overwrite SEV-SNP guest
memory resulting in loss of data integrity. (CVE-2024-36331)
Oleksii Oleksenko, Cedric Fournet, Jana Hofmann, Boris Köpf, Stavros Volos,
and Flavien Solt discovered that some AMD processors may allow an attacker
to infer data from previous stores, potentially resulting in the leakage of
privileged information. A local attacker could possibly use this to expose
sensitive information. (CVE-2024-36350, CVE-2024-36357)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
