high Nessus Plugin ID 171978

Synopsis

The remote Red Hat host is missing one or more security updates for kernel.

Description

The remote Redhat Enterprise Linux 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2023:0951 advisory.

- kernel: an out-of-bounds vulnerability in i2c-ismt driver (CVE-2022-2873)

- kernel: use-after-free caused by l2cap_reassemble_sdu() in net/bluetooth/l2cap_core.c (CVE-2022-3564)

- kernel: stack overflow in do_proc_dointvec and proc_skip_spaces (CVE-2022-4378)

- kernel: use-after-free in __nfs42_ssc_open() in fs/nfs/nfs4file.c leading to remote Denial of Service attack (CVE-2022-4379)

- kernel: Netfilter integer overflow vulnerability in nft_payload_copy_vlan (CVE-2023-0179)

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 RHEL kernel package based on the guidance in RHSA-2023:0951.
