A vulnerability in CLI management in Cisco IOS XE SD-WAN Software could allow an authenticated, local attacker to access the underlying operating system as the root user. This vulnerability is due to the way the software handles concurrent CLI sessions. An attacker could exploit this vulnerability by authenticating to the device as an administrative user and executing a sequence of commands. A successful exploit could allow the attacker to obtain access to the underlying operating system as the root user.

It was discovered that the Traffic-Control Index (TCINDEX) implementation
in the Linux kernel contained a use-after-free vulnerability. A local
attacker could use this to cause a denial of service (system crash) or
possibly execute arbitrary code. (CVE-2023-1281)
It was discovered that the System V IPC implementation in the Linux kernel
did not properly handle large shared memory counts. A local attacker could
use this to cause a denial of service (memory exhaustion). (CVE-2021-3669)
It was discovered that a use-after-free vulnerability existed in the SGI

CVE-2021-21816 [MEDIUM] Vulnerability Spotlight: Multiple vulnerabilities in D-LINK DIR-3040
Dave McDaniel discovered these vulnerabilities. Blog by Jon Munshaw.
Cisco Talos recently discovered multiple vulnerabilities in the D-LINK DIR-3040 wireless router.
The DIR-3040 is an AC3000-based wireless internet router. These vulnerabilities could allow an attacker to carry out a variety of malicious actions, including exposing sensitive information, causing a denial of service and gaining the ability to execute arbitrary code. TALOS-2021-1281 (CVE-2021-21816) and TALOS-2021-1282 (CVE-2021-21817) are information disclosure vulnerabilities in the router that could be triggered by a specially crafted network request. An attacker could exploit these vulnerabilities to view the device’s system log.
TALOS-2021-1283 (CVE-2021-21818) and TALOS-2021-1285 (CVE-2021-21820) are both hardcoded
