Amazon Linux AMI : kernel (ALAS-2023-1883)

high Nessus Plugin ID 193225

Synopsis

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

Description

The version of kernel installed on the remote host is prior to 4.14.328-174.540. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1883 advisory.

2024-04-11: CVE-2023-42754 was added to this advisory.

A race condition between two functions, lmLogClose() and txEnd(), in the Linux kernel's JFS filesystem can lead to a use-after-free vulnerability and crash. (CVE-2023-3397)

A flaw in the kernel Xen event handler can cause a deadlock with Xen console handling in unprivileged Xen guests. (CVE-2023-34324)

A NULL pointer dereference flaw was found in the Linux kernel ipv4 stack. The socket buffer (skb) was assumed to be associated with a device before calling __ip_options_compile, which is not always the case if the skb is re-routed by ipvs. This issue may allow a local user with CAP_NET_ADMIN privileges to crash the system. (CVE-2023-42754)

A heap out-of-bounds write vulnerability in the Linux kernel's Linux Kernel Performance Events (perf) component can be exploited to achieve local privilege escalation.

If perf_read_group() is called while an event's sibling_list is smaller than its child's sibling_list, it can increment or write to memory locations outside of the allocated buffer.

We recommend upgrading past commit 32671e3799ca2e4590773fd0e63aaa4229e50c06. (CVE-2023-5717)

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.
