Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of kernel installed on the remote host is prior to 5.10.178-162.673. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2023-031 advisory.

In the Linux kernel, the following vulnerability has been resolved:

sysctl: Fix data-races in proc_dou8vec_minmax(). (CVE-2022-49634)

An out-of-bounds memory access flaw was found in the Linux kernel's XFS file system in how a user restores an XFS image after failure (with a dirty log journal). This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2023-2124)

In the Linux kernel, the following vulnerability has been resolved:

Drivers: vmbus: Check for channel allocation before looking up relids (CVE-2023-53273)

In the Linux kernel, the following vulnerability has been resolved:

sctp: check send stream number after wait_for_sndbuf (CVE-2023-53296)

In the Linux kernel, the following vulnerability has been resolved:

sctp: fix a potential overflow in sctp_ifwdtsn_skip (CVE-2023-53372)

In the Linux kernel, the following vulnerability has been resolved:

tracing: Free error logs of tracing instances (CVE-2023-53375)

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: fix sysfs interface lifetime (CVE-2023-53440)

In the Linux kernel, the following vulnerability has been resolved:

scsi: iscsi_tcp: Check that sock is valid before iscsi_set_param() (CVE-2023-53464)

In the Linux kernel, the following vulnerability has been resolved:

RDMA/cma: Allow UD qp_type to join multicast only (CVE-2023-53525)

In the Linux kernel, the following vulnerability has been resolved:

nilfs2: fix potential UAF of struct nilfs_sc_info in nilfs_segctor_thread() (CVE-2023-53608)

In the Linux kernel, the following vulnerability has been resolved:

mm/swap: fix swap_info_struct race between swapoff and get_swap_pages() (CVE-2023-53623)

Tenable has extracted the preceding description block directly from the tested product 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

Run 'yum update kernel' or or 'yum update --advisory ALAS2KERNEL-5.10-2023-031' to update your system.
