critical Nessus Plugin ID 210067

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 5.15.168-114.166. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2024-056 advisory.

2024-11-08: CVE-2024-47685 was added to this advisory.

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

inet: inet_defrag: prevent sk release while still in use (CVE-2024-26921)

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

vfio/pci: fix potential memory leak in vfio_intx_enable() (CVE-2024-38632)

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

selinux,smack: don't bypass permissions check in inode_setsecctx hook (CVE-2024-46695)

fou: fix initialization of grc (CVE-2024-46865)

syzbot reported that nf_reject_ip6_tcphdr_put() was possibly sending garbage on the four reserved tcp bits (th->res1)

Use skb_put_zero() to clear the whole TCP header, as done in nf_reject_ip_tcphdr_put() (CVE-2024-47685)

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.
