| Description: | Summary:
The remote host is missing an update for the 'linux, linux-aws-5.15, linux-gcp, linux-gcp-5.15, linux-gke, linux-gkeop, linux-gkeop-5.15, linux-hwe-5.15, linux-ibm, linux-ibm-5.15, linux-kvm, linux-lowlatency, linux-lowlatency-hwe-5.15, linux-nvidia, linux-oracle, linux-oracle-5.15, linux-raspi, linux-xilinx-zynqmp' package(s) announced via the USN-7100-1 advisory.
Vulnerability Insight:
Supraja Sridhara, Benedict Schluter, Mark Kuhne, Andrin Bertschi, and
Shweta Shinde discovered that the Confidential Computing framework in
the Linux kernel for x86 platforms did not properly handle 32-bit
emulation on TDX and SEV. An attacker with access to the VMM could use
this to cause a denial of service (guest crash) or possibly execute
arbitrary code. (CVE-2024-25744)
Several security issues were discovered in the Linux kernel.
An attacker could possibly use these to compromise the system.
