Last modified

CVE-2024-25743 is a high-severity vulnerability rated 7.1/10 on the CVSS scale. In the Linux kernel through 6.9, an untrusted hypervisor can inject virtual interrupts 0 and 14 at any point in time and can trigger the SIGFPE signal handler in userspace applications. This affects AMD SEV-SNP and AMD SEV-ES.. EPSS estimates a 0.25% chance of exploitation in the next 30 days.
