Dell Dock Firmware and Dell Client Platform contain an Improper Link Resolution vulnerability during installation resulting in arbitrary folder deletion, which could lead to Privilege Escalation or Denial of Service.

Dell BIOS contains an improper input validation vulnerability. A local authenticated malicious user with admin privileges may potentially exploit this vulnerability to modify a UEFI variable, leading to denial of service and escalation of privileges

Dell BIOS contains an Out-of-Bounds Write vulnerability. A local authenticated malicious user with admin privileges could potentially exploit this vulnerability, leading to denial of service.

A potential security vulnerability has been identified in the system BIOS for certain HP PC products which might allow escalation of privilege. HP is releasing firmware updates to mitigate the potential vulnerability.

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.

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.

HP has identified a potential vulnerability in BIOS firmware of some Workstation products. Firmware updates are being released to mitigate these potential vulnerabilities.

A potential vulnerability in the SMI callback function used in the Legacy BIOS mode driver in some Lenovo Notebook models may allow an attacker with local access and elevated privileges to execute arbitrary code.

A potential security vulnerability has been identified in multiple HP products and versions which involves possible execution of arbitrary code during boot services that can result in elevation of privilege. The EFI_BOOT_SERVICES structure might be overwritten by an attacker to execute arbitrary SMM (System Management Mode) code.
