The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5566-1 advisory.

    Zhenpeng Lin discovered that the network packet scheduler implementation in the Linux kernel did not     properly remove all references to a route filter before freeing it in some situations. A local attacker     could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-2588)

    It was discovered that the netfilter subsystem of the Linux kernel did not prevent one nft object from     referencing an nft set in another nft table, leading to a use-after-free vulnerability. A local attacker     could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-2586)

    It was discovered that the implementation of POSIX timers in the Linux kernel did not properly clean up     timers in some situations. A local attacker could use this to cause a denial of service (system crash) or     execute arbitrary code. (CVE-2022-2585)

    Minh Yuan discovered that the floppy disk driver in the Linux kernel contained a race condition, leading     to 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-2022-1652)

    It was discovered that the Atheros ath9k wireless device driver in the Linux kernel did not properly     handle some error conditions, leading to a use-after-free vulnerability. A local attacker could use this     to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1679)

    Felix Fu discovered that the Sun RPC implementation in the Linux kernel did not properly handle socket     states, leading to a use-after-free vulnerability. A remote attacker could possibly use this to cause a     denial of service (system crash) or execute arbitrary code. (CVE-2022-28893)

    Johannes Wikner and Kaveh Razavi discovered that for some AMD x86-64 processors, the branch predictor     could by mis-trained for return instructions in certain circumstances. A local attacker could possibly use     this to expose sensitive information. (CVE-2022-29900)

    Johannes Wikner and Kaveh Razavi discovered that for some Intel x86-64 processors, the Linux kernel's     protections against speculative branch target injection attacks were insufficient in some circumstances. A     local attacker could possibly use this to expose sensitive information. (CVE-2022-29901)

    Arthur Mongodin discovered that the netfilter subsystem in the Linux kernel did not properly perform data     validation. A local attacker could use this to escalate privileges in certain situations. (CVE-2022-34918)

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.
