Synopsis
The remote Amazon Linux 2022 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-042 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)
An out-of-bounds (OOB) memory access flaw was found in nft_fwd_dup_netdev_offload in net/netfilter/nf_dup_netdev.c in the netfilter subcomponent in the Linux kernel due to a heap out-of- bounds write problem. This flaw allows a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a privilege escalation threat. (CVE-2022-25636)
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.
