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 4.14.345-262.561. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2024-2584 advisory.

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

 netfilter: nf_tables: disallow timeout for anonymous sets (CVE-2023-52620)

 create_empty_lvol in drivers/mtd/ubi/vtbl.c in the Linux kernel through 6.7.4 can attempt to allocate zero bytes, and crash, because of a missing check for ubi->leb_size. (CVE-2024-25739)

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

 netfilter: nf_tables: disallow anonymous set with timeout flag (CVE-2024-26642)

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

 PCI/PM: Drain runtime-idle callbacks before driver removal (CVE-2024-35809)
