The vulnerability of the tdfxfb_checkvar() function in the drivers/video/fbdev/tdfxfb.c driver module of the Linux kernel’s frame buffer device driver allows a attacker to cause a service failure.

The vulnerability of the tdfxfbcheckvar function in the drivers/video/fbdev/tdfxfb.c driver for kernel-based frame buffer devices in the Linux operating system is related to zero-division errors. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2026-74616

A flaw was found in the Linux kernel's XDP eXpress Data Path component. When XDP frames are cloned, a specially crafted frame can cause the skbsharedinfo structure to overwrite live packet data. This improper handling of memory during frame cloning can lead to corruption of XDP return metadata,...

CVE-2026-74648

A flaw was found in the Linux kernel's rtl8723bs Wi-Fi driver. This vulnerability occurs because the rtwcfg80211monitorifxmitentry function does not properly validate the length of monitor transmit frames after processing. A remote attacker could exploit this by sending a specially crafted,...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: tun: Added missing verification for short frames. The referenced commit failed to check the validity of the frame length in the tunxdpone path, which could result in a corrupted skb being sent down the stack. Even before the skb ...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: mac80211: The issue in ieee80211scanrx involves checking the skb length. This code requires hard-coded compile-time constants for determining the header length check. Instead, a dynamic determination based on the frame type shoul...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: Wifi: brcmfnotifyauthframerx – A heap overflow occurs when a short auth frame is processed. The function brcmfnotifyauthframerx retrieves the frame length from the firmware event and copies the frame body by subtracting the offse...
