Synopsis

The remote Amazon Linux 2022 host is missing a security update.

Description

It is, therefore, affected by a vulnerability as referenced in the ALAS2022-2022-101 advisory.

 - In the Linux kernel before 5.17.3, fs/io_uring.c has a use-after-free due to a race condition in io_uring timeouts. This can be triggered by a local user who has no access to any user namespace; however, the race condition perhaps can only be exploited infrequently. (CVE-2022-29582)

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

Solution

Run 'dnf update --releasever=2022.0.20220628 kernel-livepatch-5.15.29-16.111' to update your system.
