Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2023-349 advisory.

 KVM: arm64: Prevent unconditional donation of unmapped regions from the hostNOTE:
 https://source.android.com/docs/security/bulletin/2023-08-01NOTE:
 https://git.kernel.org/linus/09cce60bddd6461a93a5bf434265a47827d1bc6f (CVE-2023-21264)

 A vulnerability was found due to a missing lock for the IOPOLL in io_cqring_event_overflow() in io_uring.c in the Linux kernel. This flaw allows a local attacker with user privileges to trigger a denial of service. (CVE-2023-2430)

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 'dnf update kernel --releasever 2023.2.20230920' to update your system.
