high Nessus Plugin ID 165297

Language:

Synopsis

The remote Oracle Linux host is missing one or more security updates.

Description

The remote Oracle Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ELSA-2022-9829 advisory.

 - A use-after-free vulnerability was found in drm_lease_held in drivers/gpu/drm/drm_lease.c in the Linux kernel due to a race problem. This flaw allows a local user privilege attacker to cause a denial of service (DoS) or a kernel information leak. (CVE-2022-1280)

 - A flaw was found in the Linux kernel. Measuring usage of the shared memory does not scale with large shared memory segment counts which could lead to resource exhaustion and DoS. (CVE-2021-3669)

 - A flaw in net_rds_alloc_sgs() in Oracle Linux kernels allows unprivileged local users to crash the machine. CVSS 3.1 Base Score 6.2 (Availability impacts). CVSS Vector (CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H) (CVE-2022-21385)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel-uek-container and / or kernel-uek-container-debug packages.
