CVE-2026-43267

A flaw was found in the rtw89 Wi-Fi driver within the Linux kernel. This vulnerability occurs when the beacon interval, a timing parameter used in Wi-Fi communication, is set to zero. This can lead to a division by zero error during subsequent calculations, potentially causing system instability ...

CVE-2024-47724 wifi: ath11k: use work queue to process beacon tx event

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: use work queue to process beacon tx event Commit 3a415daa3e8b "wifi: ath11k: add P2P IE in beacon template" from Feb 28, 2024 linux-next, leads to the following Smatch static checker warning:...

kernel: buffer-overflow hardening in WiFi beacon validation code.

A flaw in the Linux kernel's WiFi beacon validation code was discovered. The code does not check the length of the variable length elements in the beacon head potentially leading to a buffer overflow. System availability, as well as data confidentiality and integrity, can be impacted by this...

USN-4210-1 linux, linux-aws, linux-aws-hwe, linux-gcp, linux-gke-4.15, linux-hwe, linux-kvm, linux-oem, linux-oracle, linux-raspi2, linux-snapdragon vulnerabilities

It was discovered that a buffer overflow existed in the 802.11 Wi-Fi configuration interface for the Linux kernel when handling beacon settings. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary code. CVE-2019-16746 Nicolas Waisman discovered...

USN-4209-1 linux, linux-aws, linux-aws-5.0, linux-gcp, linux-gke-5.0, linux-hwe, linux-kvm, linux-oem-osp1, linux-oracle, linux-oracle-5.0, linux-raspi2 vulnerabilities

Jann Horn discovered that the OverlayFS and ShiftFS Drivers in the Linux kernel did not properly handle reference counting during memory mapping operations when used in conjunction with AUFS. A local attacker could use this to cause a denial of service system crash or possibly execute arbitrary...
