Amazon Linux 2 : kernel (ALAS-2022-1903)

high Nessus Plugin ID 168676

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 4.14.301-224.520. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1903 advisory.

2024-06-06: CVE-2023-26607 was added to this advisory.

A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function ipv6_renew_options of the component IPv6 Handler. The manipulation leads to memory leak. The attack can be launched remotely. It is recommended to apply a patch to fix this issue.
The identifier VDB-211021 was assigned to this vulnerability. (CVE-2022-3524)

A use-after-free flaw was found in the Linux kernel's implementation of logical link control and adaptation protocol (L2CAP), part of the Bluetooth stack in the l2cap_connect and l2cap_le_connect_req functions. An attacker with physical access within the range of standard Bluetooth transmission could execute code leaking kernel memory via Bluetooth if within proximity of the victim. (CVE-2022-42896)

In the Linux kernel 6.0.8, there is an out-of-bounds read in ntfs_attr_find in fs/ntfs/attrib.c.
(CVE-2023-26607)

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.
