A flaw incorrect access control in the Linux kernel USB core subsystem was found in the way user attaches usb device. A local user could use this flaw to crash the system.

A potential security vulnerability has been identified in certain HP Workstation BIOS (UEFI firmware) which may allow arbitrary code execution. HP is releasing firmware mitigations for the potential vulnerability.

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.

A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition.

An attacker with physical access to Moxa's bootloader versions of UC-8580 Series V1.1, UC-8540 Series V1.0 to V1.2, UC-8410A Series V2.2, UC-8200 Series V1.0 to V2.4, UC-8100A-ME-T Series V1.0 to V1.1, UC-8100 Series V1.2 to V1.3, UC-5100 Series V1.2, UC-3100 Series V1.2 to V2.0, UC-2100 Series V1.3 to V1.5, and UC-2100-W Series V1.3 to V1.5 can initiate a restart of the device and gain access to its BIOS. Command line options can then be altered, allowing the attacker to access the terminal. From the terminal, the attacker can modify the device’s authentication files to create a new user and gain full access to the system.

By Deeba Ahmed ESET assigned the vulnerability a CVSS score of 8.1 and tracked it as CVE-2022-4020. This is a post from HackRead.com Read the original post: Acer Laptop Vulnerability Allows Malware Infection During Secure Boot

The new Microsoft Defender for Endpoint capabilities include built-in protection and scanning network traffic for malicious activity.

Acer has released a firmware update to address a security vulnerability that could be potentially weaponized to turn off UEFI Secure Boot on affected machines. Tracked as CVE-2022-4020, the high-severity vulnerability affects five different models that consist of Aspire A315-22, A115-21, and A315-22G, and Extensa EX215-21 and EX215-21G. The PC maker described the vulnerability as
