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 5.15.79-51.138. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.15-2022-011 advisory.

A vulnerability classified as problematic has been found in Linux Kernel. This affects the function fib_nh_match of the file net/ipv4/fib_semantics.c of the component IPv4 Handler. The manipulation leads to out-of-bounds read. It is possible to initiate the attack remotely. It is recommended to apply a patch to fix this issue. The identifier VDB-210357 was assigned to this vulnerability. (CVE-2022-3435)

A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function ipv6_renew_options of the component IPv6 Handler. The manipulation leads to memory leak. The attack can be launched remotely. It is recommended to apply a patch to fix this issue.
The identifier VDB-211021 was assigned to this vulnerability. (CVE-2022-3524)

A vulnerability, which was classified as problematic, has been found in Linux Kernel. This issue affects the function unix_sock_destructor/unix_release_sock of the file net/unix/af_unix.c of the component BPF.
The manipulation leads to memory leak. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211043. (CVE-2022-3543)

A vulnerability classified as critical was found in Linux Kernel. Affected by this vulnerability is the function l2cap_reassemble_sdu of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The manipulation leads to use after free. It is recommended to apply a patch to fix this issue. The associated identifier of this vulnerability is VDB-211087. (CVE-2022-3564)

A vulnerability has been found in Linux Kernel and classified as problematic. This vulnerability affects the function l2cap_recv_acldata of the file net/bluetooth/l2cap_core.c of the component Bluetooth. The manipulation leads to memory leak. It is recommended to apply a patch to fix this issue. VDB-211918 is the identifier assigned to this vulnerability. (CVE-2022-3619)

A vulnerability was found in Linux Kernel. It has been declared as problematic. Affected by this vulnerability is the function follow_page_pte of the file mm/gup.c of the component BPF. The manipulation leads to race condition. The attack can be launched remotely. It is recommended to apply a patch to fix this issue. The identifier VDB-211921 was assigned to this vulnerability. (CVE-2022-3623)

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

arm64: entry: avoid kprobe recursion (CVE-2022-49888)

A use-after-free flaw was found in qdisc_graft in net/sched/sch_api.c in the Linux Kernel due to a race problem. This flaw leads to a denial of service issue. (CVE-2023-0590)

An out-of-bounds memory access flaw was found in the Linux kernel's TUN/TAP device driver functionality in how a user generates a malicious (too big) networking packet when napi frags is enabled. This flaw allows a local user to crash or potentially escalate their privileges on the system. (CVE-2023-3812)

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.
