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 4.14.273-207.502. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2-2022-1768 advisory.- A flaw was found in the Linux kernel in linux/net/netfilter/nf_tables_api.c of the netfilter subsystem.
This flaw allows a local user to cause an out-of-bounds write issue. (CVE-2022-1015)
- A flaw was found in the Linux kernel in net/netfilter/nf_tables_core.c:nft_do_chain, which can cause a use-after-free. This issue needs to handle 'return' with proper preconditions, as it can lead to a kernel information leak problem caused by a local, unprivileged attacker. (CVE-2022-1016)
