Ubuntu 20.04 LTS / 22.04 LTS : Linux kernel vulnerabilities (USN-6080-1)

high Nessus Plugin ID 175883

Language:

Synopsis

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

Description

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-6080-1 advisory.

 It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. (CVE-2022-27672)

 Zheng Wang discovered that the Intel i915 graphics driver 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-2022-3707)

 Jordy Zomer and Alexandra Sandulescu discovered that the Linux kernel did not properly implement speculative execution barriers in usercopy functions in certain situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2023-0459)

 It was discovered that the TLS subsystem in the Linux kernel contained a type confusion vulnerability in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-1075)

 It was discovered that the Reliable Datagram Sockets (RDS) protocol implementation in the Linux kernel contained a type confusion vulnerability in some situations. An attacker could use this to cause a denial of service (system crash). (CVE-2023-1078)

 Xingyuan Mo discovered that the x86 KVM implementation in the Linux kernel did not properly initialize some data structures. A local attacker could use this to expose sensitive information (kernel memory).
 (CVE-2023-1513)

 It was discovered that the Android Binder IPC subsystem in the Linux kernel did not properly validate inputs 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 possibly execute arbitrary code. (CVE-2023-20938)

 It was discovered that a use-after-free vulnerability existed in the iSCSI TCP implementation in the Linux kernel. A local attacker could possibly use this to cause a denial of service (system crash).
 (CVE-2023-2162)

 It was discovered that the NET/ROM protocol implementation in the Linux kernel contained a race condition 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 possibly execute arbitrary code. (CVE-2023-32269)

 Duoming Zhou discovered that a race condition existed in the infrared receiver/transceiver driver in the Linux kernel, leading to a use-after- free vulnerability. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-1118)

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.
