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 5.4.181-99.354. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2KERNEL-5.4-2022-023 advisory.
2024-08-27: CVE-2022-48804 was added to this advisory.
2024-08-27: CVE-2022-48788 was added to this advisory.
2024-08-27: CVE-2022-48823 was added to this advisory.
2024-08-27: CVE-2022-48809 was added to this advisory.
2024-08-27: CVE-2022-48805 was added to this advisory.
2024-08-27: CVE-2022-48790 was added to this advisory.
2024-08-01: CVE-2022-48724 was added to this advisory.
2024-08-01: CVE-2022-48734 was added to this advisory.
2024-08-01: CVE-2022-48743 was added to this advisory.
2024-08-01: CVE-2022-48742 was added to this advisory.
2024-08-01: CVE-2022-48711 was added to this advisory.
AMD recommends using a software mitigation for this issue, which the kernel is enabling by default. The Linux kernel will use the generic retpoline software mitigation, instead of the specialized AMD one, on AMD instances (*5a*). This is done by default, and no administrator action is needed. (CVE-2021-26341)

(CVE-2021-26401)
An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system. (CVE-2021-4197)
Non-transparent sharing of branch predictor selectors between contexts in some Intel(R) Processors may allow an authorized user to potentially enable information disclosure. (CVE-2022-0001)
Non-transparent sharing of branch predictor within a context in some Intel(r) Processors may allow an authorized user to potentially enable information disclosure via local access. (CVE-2022-0002)
A stack overflow flaw was found in the Linux kernel's TIPC protocol functionality in the way a user sends a packet with malicious content where the number of domain member nodes is higher than the 64 allowed.
This flaw allows a remote user to crash the system or possibly escalate their privileges if they have access to the TIPC network. (CVE-2022-0435)
The Amazon Linux kernel now enables, by default, a software mitigation for this issue, on all ARM-based EC2 instance types. (CVE-2022-23960)
A flaw was found in the Linux kernel's driver for the ASIX AX88179_178A-based USB 2.0/3.0 Gigabit Ethernet Devices. The vulnerability contains multiple out-of-bounds reads and possible out-of-bounds writes.
(CVE-2022-2964)
