Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux 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 version of kernel-generic installed on the remote host is prior to 5.15.118 / 5.15.118_smp. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2023-172-02 advisory.

    New kernel packages are available for Slackware 15.0 to fix security issues.

The remote Ubuntu 22.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6133-1 advisory.

    It was discovered that the Traffic-Control Index (TCINDEX) implementation in the Linux kernel did not     properly perform filter deactivation in some situations. A local attacker could possibly use this to gain     elevated privileges. Please note that with the fix for this CVE, kernel support for the TCINDEX classifier     has been removed. (CVE-2023-1829)

    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 a race condition existed in the io_uring subsystem in the Linux kernel, 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-2023-1872)

    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)
