CVE-2024-25743
CVSS v3.1
7.1
High
| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N |
Name of the Vulnerable Software and Affected Versions:
Linux kernel versions prior to 6.9
Description:
The issue is related to the implementation of the SEV-SNP and SEV-ES protective mechanisms in the Linux kernel, which can be exploited by an untrusted hypervisor to inject virtual interrupts and trigger the SIGFPE signal handler in userspace applications. This can potentially impact the confidentiality and integrity of protected information. An estimated number of affected devices is not provided, and there is no information about real-world incidents where this issue was exploited.
Recommendations:
For Linux kernel versions prior to 6.9, update to a version that includes the fix for this issue to prevent potential exploitation.
As a temporary workaround, consider restricting access to the SIGFPE signal handler in userspace applications until a patch is available.
Fix
