A vulnerability was reported in BIOS for ThinkPad P14s Gen 2, P15s Gen 2, T14 Gen 2, and T15 Gen 2 that could cause the system to recover to insecure settings if the BIOS becomes corrupt.

Dell BIOS contain a Time-of-check Time-of-use vulnerability in BIOS. A local authenticated malicious user with physical access to the system could potentially exploit this vulnerability by using a specifically timed DMA transaction during an SMI in order to gain arbitrary code execution on the system.

Dell BIOS contains an improper authentication vulnerability. A malicious user with physical access to the system may potentially exploit this vulnerability in order to modify a security-critical UEFI variable without knowledge of the BIOS administrator.

Improper buffer restrictions in the BIOS firmware for some Intel(R) Processors may allow a privileged user to potentially enable information disclosure via local access.

Improper input validation in firmware for some Intel(R) PCSD BIOS before version 02.01.0013 may allow a privileged user to potentially enable information disclosure via local access.

Race condition in some Intel(R) NUC BIOS firmware may allow a privileged user to potentially enable escalation of privilege via local access.

Exposure of sensitive information to an unauthorized actor in BIOS firmware for some Intel(R) NUCs may allow a privilege user to potentially enable information disclosure via local access.

Cybersecurity researchers have disclosed details of a trio of side-channel attacks that could be exploited to leak sensitive data from modern CPUs. Called Collide+Power (CVE-2023-20583), Downfall (CVE-2022-40982), and Inception (CVE-2023-20569), the novel methods follow the disclosure of another newly discovered security vulnerability affecting AMD's Zen 2 architecture-based processors known as

An out-of-bounds memory access flaw was found in the Linux kernel’s do_journal_end function when the fails array-index-out-of-bounds in fs/reiserfs/journal.c could happen. This flaw allows a local user to crash the system.

An authentication bypass vulnerability exists in Suprema BioStar 2 before 2.9.1, which allows unauthenticated users to access some functionality on BioStar 2 servers.
