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 5.4.188-104.359. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-025 advisory.

2024-08-27: CVE-2022-48834 was added to this advisory.

Product: AndroidVersions: Android kernelAndroid ID: A-224546354References: Upstream kernel (CVE-2022-20368)

A buffer overflow flaw was found in the Linux kernel's NFC protocol functionality. This flaw allows a local user to crash or escalate their privileges on the system. (CVE-2022-26490)

A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat. (CVE-2022-27666)

In the Linux kernel before 5.17.1, a refcount leak bug was found in net/llc/af_llc.c. (CVE-2022-28356)

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

usb: usbtmc: Fix bug in pipe direction for control transfers (CVE-2022-48834)

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.
