Amazon Linux 2023 : bpftool, kernel, kernel-devel (ALAS2023-2024-765)

critical Nessus Plugin ID 211369

Synopsis

The remote Amazon Linux 2023 host is missing a security update.

Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2024-765 advisory.

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

 Bluetooth: hci_sock: Fix not validating setsockopt user input (CVE-2024-35963)

 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)

 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 'dnf update kernel --releasever 2023.6.20241111' to update your system.
