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-2023:4801 advisory.

- kernel: kernel info leak issue in pfkey_register (CVE-2022-1353)

- kernel: unmap_mapping_range() race with munmap() on VM_PFNMAP mappings leads to stale TLB entry (CVE-2022-39188)

- kernel: speculative pointer dereference in do_prlimit() in kernel/sys.c (CVE-2023-0458)

- kernel: ipvlan: out-of-bounds write caused by unclear skb->cb (CVE-2023-3090)

- kernel: tls: race condition in do_tls_getsockopt may lead to use-after-free or NULL pointer dereference (CVE-2023-28466)

- kernel: buffer overflow in ceph file net/ceph/messenger_v2.c (CVE-2023-44466)

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