    Jos Oliveira and Rodrigo Branco discovered that the prctl syscall implementation in the Linux kernel did     not properly protect against indirect branch prediction attacks in some situations. A local attacker could     possibly use this to expose sensitive information. (CVE-2023-0045)

    It was discovered that a use-after-free vulnerability existed in the Advanced Linux Sound Architecture     (ALSA) subsystem. A local attacker could use this to cause a denial of service (system crash).
    (CVE-2023-0266)

    It was discovered that the io_uring subsystem in the Linux kernel contained a use-after-free     vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or     execute arbitrary code. (CVE-2023-0469)

    It was discovered that the CIFS network file system implementation in the Linux kernel contained a user-     after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system     crash) or execute arbitrary code. (CVE-2023-1195)

    It was discovered that the RNDIS USB driver in the Linux kernel contained an integer overflow     vulnerability. A local attacker with physical access could plug in a malicious USB device to cause a     denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-23559)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Ubuntu 22.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5970-1 advisory.
