medium Nessus Plugin ID 234965

Language:

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 5.10.167-147.601. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.10-2025-089 advisory.

 A flaw was found in the Linux kernel's Layer 2 Tunneling Protocol (L2TP). A missing lock when clearing sk_user_data can lead to a race condition and NULL pointer dereference. A local user could use this flaw to potentially crash the system causing a denial of service. (CVE-2022-4129)

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

 dmaengine: Fix double increment of client_count in dma_chan_get() (CVE-2022-49753)

 A memory corruption flaw was found in the Linux kernel's human interface device (HID) subsystem in how a user inserts a malicious USB device. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2023-1073)

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

 net: fix UaF in netns ops registration error path (CVE-2023-52999)

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

 net/sched: sch_taprio: fix possible use-after-free (CVE-2023-53021)

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' to update your system.
