Overview

Affected versions of this package are vulnerable to Buffer Overflow in the snp_filter_reserved_mem_regions process. An attacker can achieve arbitrary kernel memory writes, information disclosure, or cause a denial of service by triggering a controlled out-of-bounds write to heap memory during SEV-SNP platform initialization via KVM_SEV_INIT2 ioctl or during kernel boot-time SEV-SNP platform initialization.

Note: The Linux kernel project assigns a CVE to every bug fix it ships, whether or not the bug has been shown to be exploitable. This advisory was generated from that process and has not been individually assessed for exploitability. See the kernel's CVE process documentation: https://github.com/torvalds/linux/blob/master/Documentation/process/cve.rst
