In the Linux kernel, the following vulnerability has been resolved: riscv/mm: Add handling for VM_FAULT_SIGSEGV in mm_fault_error() Handle VM_FAULT_SIGSEGV in the page fault path so that we correctly kill the process and we don't BUG() the kernel.

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7100-2 advisory.

    Supraja Sridhara, Benedict Schlter, 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)
