OpenVPN Access Server 2.10 and prior versions are susceptible to resending multiple packets in a response to a reset packet sent from the client which the client again does not respond to, resulting in a limited amplification attack.

NVIDIA DGX A100 contains a vulnerability in SBIOS in the BiosCfgTool, where a local user with elevated privileges can read and write beyond intended bounds in SMRAM, which may lead to code execution, escalation of privileges, denial of service, and information disclosure. The scope of impact can extend to other components.

Prior Dell BIOS versions contain an Input Validation vulnerability. A locally authenticated malicious user could potentially exploit this vulnerability by sending malicious input to an SMI in order to bypass security controls in SMM.

SoftGuard Web (SGW) versions prior to 5.1.5 suffer from html injection and arbitrary file system access allow for file downloads.

net/netfilter/nf_tables_api.c in the Linux kernel through 5.18.1 allows a local user (able to create user/net namespaces) to escalate privileges to root because an incorrect NFT_STATEFUL_EXPR check leads to a use-after-free.

An analysis of leaked chats from the notorious Conti ransomware group earlier this year has revealed that the syndicate has been working on a set of firmware attack techniques that could offer a path to accessing privileged code on compromised devices.
