kernel: wifi: mt76: mt7921: fix error code of return in mt7921_acpi_read

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: fix error code of return in mt7921acpiread Kernel NULL pointer dereference when ACPI SAR table isn't implemented well. Fix the error code of return to mark the ACPI SAR table as invalid. 5.077128 mt7921e...

DEBIAN-CVE-2023-47233

The brcm80211 component in the Linux kernel through 6.5.10 has a brcmfcfg80211detach use-after-free in the device unplugging disconnect the USB by hotplug code. For physically proximate attackers with local access, this "could be exploited in a real world scenario." This is related to...

PT-2025-2275

Name of the Vulnerable Software and Affected Versions MediaTek WLAN STA driver affected versions not specified Description The issue is related to a possible out of bounds write in the wlan STA driver due to improper input validation. This could lead to remote code execution with no additional...

Zephyr Security Breach

Zephyr is an extensible real-time operating system RTOS open-sourced by the Zephyr Project. A security vulnerability exists in Zephyr 3.4.0 and earlier versions, which stems from a buffer overflow vulnerability in the Zephyr IEEE 802.15.4 nRF 15.4 driver...

The vulnerability of MediaTek’s WLAN driver microprogramming software allows a hacker to gain unauthorized access to protected information.

The vulnerability of the WLAN driver software developed by MediaTek relates to reading data outside the buffer in memory. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information...
