An update of the linux package has been released.

The CentOS Linux 8.5 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.5:CLSA-2023:1690294029 advisory.

  - A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that     allows local users to create files for the XFS file-system with an unintended group ownership and with     group execution and SGID permission bits set, in a scenario where a directory is SGID and belongs to a     certain group and is writable by a user who is not a member of this group. This can lead to excessive     permissions granted in case when they should not. This vulnerability is similar to the previous     CVE-2018-13405 and adds the missed fix for the XFS. (CVE-2021-4037)

  - A flaw was found in the KVM's AMD code for supporting the Secure Encrypted Virtualization-Encrypted State     (SEV-ES). A KVM guest using SEV-ES can trigger out-of-bounds reads and writes in the host kernel via a     malicious VMGEXIT for a string I/O instruction (for example, outs or ins) using the exit reason     SVM_EXIT_IOIO. This issue results in a crash of the entire system or a potential guest-to-host escape     scenario. (CVE-2021-4093)

  - A random memory access flaw was found in the Linux kernel's GPU i915 kernel driver functionality in the     way a user may run malicious code on the GPU. This flaw allows a local user to crash the system or     escalate their privileges on the system. (CVE-2022-0330)

  - A use-after-free flaw was found in the Linux kernel's sound subsystem in the way a user triggers     concurrent calls of PCM hw_params. The hw_free ioctls or similar race condition happens inside ALSA PCM     for other ioctls. This flaw allows a local user to crash or potentially escalate their privileges on the     system. (CVE-2022-1048)

  - With shadow paging enabled, the INVPCID instruction results in a call to kvm_mmu_invpcid_gva. If INVPCID     is executed with CR0.PG=0, the invlpg callback is not set and the result is a NULL pointer dereference.
    (CVE-2022-1789)

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

The CentOS Linux 8.4 host has packages installed that are affected by multiple vulnerabilities as referenced in the TuxCare CENTOS8.4:CLSA-2023:1690287378 advisory.

    (CVE-2022-1789)

  - In verity_target of dm-verity-target.c, there is a possible way to modify read-only files due to a missing     permission check. This could lead to local escalation of privilege with System execution privileges     needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid     ID: A-234475629References: Upstream kernel (CVE-2022-20572)
