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 5.15.184-125.189. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2025-077 advisory.

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

 btrfs: don't BUG_ON() when 0 reference count at btrfs_lookup_extent_info() (CVE-2024-46751)

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

 sctp: add mutual exclusion in proc_sctp_do_udp_port() (CVE-2025-22062)

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.
