Ubuntu 22.04 LTS : Linux kernel vulnerabilities (USN-5469-1)

high Nessus Plugin ID 161955

Language:

Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5469-1 advisory.

 It was discovered that the Linux kernel did not properly restrict access to the kernel debugger when booted in secure boot environments. A privileged attacker could use this to bypass UEFI Secure Boot restrictions. (CVE-2022-21499)

 Aaron Adams discovered that the netfilter subsystem in the Linux kernel did not properly handle the removal of stateful expressions in some situations, 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-2022-1966)

 Billy Jheng Bing Jhong discovered that the CIFS network file system implementation in the Linux kernel did not properly validate arguments to ioctl() in some situations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-0168)

 Hu Jiahui discovered that multiple race conditions existed in the Advanced Linux Sound Architecture (ALSA) framework, leading to use-after-free vulnerabilities. A local attacker could use these to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2022-1048)

 Qiuhao Li, Gaoning Pan and Yongkang Jia discovered that the KVM implementation in the Linux kernel did not properly perform guest page table updates in some situations. An attacker in a guest vm could possibly use this to crash the host OS. (CVE-2022-1158)

 It was discovered that the implementation of the 6pack and mkiss protocols in the Linux kernel did not handle detach events properly in some situations, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1195)

 Duoming Zhou discovered that the 6pack protocol implementation in the Linux kernel did not handle detach events properly in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash). (CVE-2022-1198)

 Duoming Zhou discovered that the AX.25 amateur radio protocol implementation in the Linux kernel did not handle detach events properly in some situations. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2022-1199)

 Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux kernel during device detach operations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1204)

 Duoming Zhou discovered race conditions in the AX.25 amateur radio protocol implementation in the Linux kernel, leading to use-after-free vulnerabilities. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1205)

 Qiuhao Li, Gaoning Pan, and Yongkang Jia discovered that the kvm implementation in the Linux kernel did not handle releasing a virtual cpu properly. A local attacker in a guest VM coud possibly use this to cause a denial of service (host system crash). (CVE-2022-1263)

 It was discovered that the PF_KEYv2 implementation in the Linux kernel did not properly initialize kernel memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2022-1353)

 It was discovered that the implementation of X.25 network protocols in the Linux kernel did not terminate link layer sessions properly. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-1516)

 It was discovered that the ACRN Hypervisor Service Module implementation in the Linux kernel did not properly deallocate memory in some situations. A local privileged attacker could possibly use this to cause a denial of service (memory exhaustion). (CVE-2022-1651)

 It was discovered that the RxRPC session socket implementation in the Linux kernel did not properly handle ioctls called when no security protocol is given. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information (kernel memory). (CVE-2022-1671)

 Ziming Zhang discovered that the netfilter subsystem in the Linux kernel did not properly validate sets with multiple ranged fields. A local attacker could use this to cause a denial of service or execute arbitrary code. (CVE-2022-1972)

 discovered that the 802.2 LLC type 2 driver in the Linux kernel did not properly perform reference counting in some error conditions. A local attacker could use this to cause a denial of service.
 (CVE-2022-28356)

 It was discovered that the 8 Devices USB2CAN interface implementation in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-28388)

 It was discovered that the Microchip CAN BUS Analyzer interface implementation in the Linux kernel did not properly handle certain error conditions, leading to a double-free. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2022-28389)

 It was discovered that the EMS CAN/USB interface implementation in the Linux kernel contained a double- free vulnerability when handling certain error conditions. A local attacker could use this to cause a denial of service (memory exhaustion). (CVE-2022-28390)

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.

Solution

Update the affected kernel package.
