The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6927-1 advisory.

    Ziming Zhang discovered that the DRM driver for VMware Virtual GPU did not properly handle certain error     conditions, leading to a NULL pointer dereference. A local attacker could possibly trigger this     vulnerability to cause a denial of service. (CVE-2022-38096)

    Gui-Dong Han discovered that the software RAID driver in the Linux kernel contained a race condition,     leading to an integer overflow vulnerability. A privileged attacker could possibly use this to cause a     denial of service (system crash). (CVE-2024-23307)

    It was discovered that a race condition existed in the Bluetooth subsystem in the Linux kernel when     modifying certain settings values through debugfs. A privileged local attacker could use this to cause a     denial of service. (CVE-2024-24857, CVE-2024-24858, CVE-2024-24859)

    Bai Jiaju discovered that the Xceive XC4000 silicon tuner device driver in the Linux kernel contained a     race condition, leading to an integer overflow vulnerability. An attacker could possibly use this to cause     a denial of service (system crash). (CVE-2024-24861)

    Chenyuan Yang discovered that the Unsorted Block Images (UBI) flash device volume management subsystem did     not properly validate logical eraseblock sizes in certain situations. An attacker could possibly use this     to cause a denial of service (system crash). (CVE-2024-25739)

    Benedict Schlter, Supraja Sridhara, Andrin Bertschi, and Shweta Shinde discovered that an untrusted     hypervisor could inject malicious #VC interrupts and compromise the security guarantees of AMD SEV-SNP.
    This flaw is known as WeSee. A local attacker in control of the hypervisor could use this to expose     sensitive information or possibly execute arbitrary code in the trusted execution environment.
    (CVE-2024-25742)
