Potential security vulnerabilities have been identified in the BIOS (UEFI Firmware) for certain HP PC products, which might allow arbitrary code execution. HP is releasing firmware updates to mitigate these potential vulnerabilities.

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

Dell BIOS contains a Stack based buffer overflow vulnerability. A local authenticated attacker could potentially exploit this vulnerability by using an SMI to send larger than expected input to a parameter to gain arbitrary code execution in SMRAM.

Dell BIOS contains a Time-of-check Time-of-use vulnerability. A local authenticated malicious user could\u00a0potentially exploit this vulnerability by using a specifically timed DMA transaction during an SMI to gain arbitrary code execution on the system.

Dell BIOS contains an improper input validation vulnerability. A local authenticated malicious user with admin privileges may potentially exploit this vulnerability in order to modify a UEFI variable.

Dell BIOS contains a heap buffer overflow vulnerability. A local attacker with admin privileges could potentially exploit this vulnerability to perform an arbitrary write to SMRAM during SMM.

An information leak vulnerability in the SMI Set BIOS Password SMI Handler in some Lenovo models may allow an attacker with local access and elevated privileges to read SMM memory.

A potential vulnerability has been identified in the system BIOS for certain HP PC products which may allow escalation of privileges and code execution. HP is releasing firmware updates to mitigate the potential vulnerability.
