      <title>CVE-2025-38560 — x86/sev: Evict cache lines during SNP memory validation</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2025-38560</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Linux&lt;/p&gt;
&lt;p&gt;In the Linux kernel, the following vulnerability has been resolved:&lt;/p&gt;
&lt;p&gt;x86/sev: Evict cache lines during SNP memory validation&lt;/p&gt;
&lt;p&gt;An SNP cache coherency vulnerability requires a cache line eviction
mitigation when validating memory after a page state change to private.
The specific mitigation is to touch the first and last byte of each 4K
page that is being validated. There is no need to perform the mitigation
when performing a page state change to shared and rescinding validation.&lt;/p&gt;
&lt;p&gt;CPUID bit Fn8000001F_EBX[31] defines the COHERENCY_SFW_NO CPUID bit
that, when set, indicates that the software mitigation for this
vulnerability is not needed.&lt;/p&gt;
&lt;p&gt;Implement the mitigation and invoke it when validating memory (making it
private) and the COHERENCY_SFW_NO bit is not set, indicating the SNP
guest is vulnerable.&lt;/p&gt;</description>

      <title>USN-7879-1 — linux, linux-aws, linux-gcp, linux-hwe-6.14, linux-oracle, linux-realtime vulnerabilities</title>
      <link>https://cve.radiocsirt.org/vuln/usn-7879-1</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; Ubuntu:24.04:LTS: linux-hwe-6.14&lt;/p&gt;
&lt;p&gt;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)&lt;/p&gt;
&lt;p&gt;Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
This update corrects flaws in the following subsystems:
  - ARM64 architecture;
  - PowerPC architecture;
  - S390 architecture;
  - x86 architecture;
  - Network block device driver;
  - Character device driver;
  - Clock framework and drivers;
