Amazon Linux 2022 : (ALAS2022-2022-125)
high Nessus Plugin ID 164742

Synopsis
The remote Amazon Linux 2022 host is missing a security update.Description
It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2022-2022-125 advisory.- Mis-trained branch predictions for return instructions may allow arbitrary speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-29900)
- Intel microprocessor generations 6 to 8 are affected by a new Spectre variant that is able to bypass their retpoline mitigation in the kernel to leak arbitrary data. An attacker with unprivileged user access can hijack return instructions to achieve arbitrary speculative code execution under certain microarchitecture-dependent conditions. (CVE-2022-29901)
- The Linux kernel before 5.18.13 lacks a certain clear operation for the block starting symbol (.bss). This allows Xen PV guest OS users to cause a denial of service or gain privileges. (CVE-2022-36123)
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
Solution
Run 'dnf update kernel --releasever=2022.0.20220810' to update your system.See Also
