Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A vulnerability in the Linux kernel has been identified, specifically in the xen hypercall hvm function used when running as a Xen PVH guest. This function clobbers the %rbx register,...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: x86/xen: Do not perform the PV iret hypercall through the hypercall page. Instead of jumping to the Xen hypercall page to execute the iret hypercall, the required sequence is directly coded in the xen-asm.S file. This action is...

CVE-2024-55881
CVE-2024-55881 : In the Linux kernel, KVM for x86 had a fix to correctly detect 64‑bit hypercalls during complete_hypercall_exit() for guests with protected state (e.g., SEV-ES/SEV-SNP). The change replaces is_64_bit_mode() with is_64_bit_hypercall() to determine 64‑bit mode when the vCPU state n...
