SUSE CVE-2026-31605
In the Linux kernel, the following vulnerability has been resolved: fbdev: udlfb: avoid divide-by-zero on FBIOPUTVSCREENINFO Much like commit 19f953e74356 "fbdev: fbpm2fb: Avoid potential divide by zero error", we also need to prevent that same crash from happening in the udlfb driver as it uses...
DEBIAN-CVE-2026-31603
In the Linux kernel, the following vulnerability has been resolved: staging: sm750fb: fix division by zero in pstohz pstohz is called from hwsm750crtcsetmode without validating that pixclock is non-zero. A zero pixclock passed via FBIOPUTVSCREENINFO causes a division by zero. Fix by rejecting zer...

SUSE CVE-2022-49978
In the Linux kernel, the following vulnerability has been resolved: fbdev: fbpm2fb: Avoid potential divide by zero error In dofbioctl of fbmem.c, if cmd is FBIOPUTVSCREENINFO, var will be copied from user, then go through fbsetvar and info-fbops-fbcheckvar which could may be pm2fbcheckvar. Along...
kernel: tty: Fix out-of-bound vmalloc access in imageblit
A vulnerability was found in the Linux kernel's tty subsystem within the imageblit function when a userspace program performs an ioctl operation with the FBIOPUTVSCREENINFO command, passing a fbvarscreeninfo structure with limited fields. If the structure’s values remain unchanged from a previous...
kernel: malicious data for FBIOPUT_VSCREENINFO ioctl may cause OOB write memory
An out-of-bounds write flaw was found in the Linux kernel’s framebuffer-based console driver functionality in the way a user triggers ioctl FBIOPUTVSCREENINFO with malicious data. This flaw allows a local user to crash or potentially escalate their privileges on the system...
