SUSE CVE-2026-98838
In the Linux kernel, the following vulnerability has been resolved: vt: skip screen update for DEC alignment test on backgroup consoles BUG Recently, we encountered a KASAN warning as follows: BUG: KASAN: slab-out-of-bounds in fbpadalignedbuffer+0x11f/0x140 Read of size 1 at addr ff1100015fd9f6a4...
CVE-2026-80786
A flaw was found in the fbdev subsystem of the Linux kernel. This vulnerability occurs because certain user-invoked display mode changes, specifically those not using the FBIOPUTVSCREENINFO ioctl, fail to properly update the fbcon state. A local user could potentially exploit this by triggering a...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: fbcon: check the return value of con2fbacquirenewinfo. If fbconopen fails when called from con2fbacquirenewinfo, then info-fbconpar pointer remains NULL, and this pointer will be dereferenced later. A check for the return value o...
Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: fbdev: fbcon: A out-of-bounds read occurred in the errout section of fbcondosetfont. When fbcondosetfont fails e.g., due to a memory allocation failure within vcresize under heavy memory pressure, it jumps to the errout label to...
Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: fbcon: Fixed the issue of NULL pointer dereferencing for a console without vcdata. The function fbconnewmodelist is called when the modelist of a framebuffer changes. For each console mapped to it using fbdisplayi.mode, it reads...
Astra Linux – Vulnerability in Linux
A buffer overflow attack in fbcon in the Linux kernel before version 5.9.7 could be exploited by local attackers to read privileged information or potentially cause the kernel to crash. This issue is identified as CID-3c4e0dff2095. This vulnerability arises because the KDFONTOPCOPY function in...

The Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-202672468 advisory. kernel: fbcon: Set fbdisplayi-mode to NULL when the mode is released CVE-2025-40323 kernel: ext4: fix e4b bitmap inconsistency reports CVE-2026-45942...
kernel: fbcon: Set fb_display[i]->mode to NULL when the mode is released
A use-after-free vulnerability was identified in the Linux kernel framebuffer console fbcon subsystem. During framebuffer unregistration, the kernel freed the memory for a display mode but did not clear the corresponding fbdisplayi-mode pointer. Subsequent framebuffer ioctl operations could then...
