A recently assigned CVE, CVE-2025-38198, identifies a memory-safety bug in the Linux kernel's framebuffer console subsystem (fbcon) that can trigger an array-index-out-of-bounds error when the system processes writes to the fbcon store_modes sysfs node. The flaw is rooted in insufficient...

A recently published Linux kernel security entry — CVE-2025-40322 — addresses a bounds‑checking defect in the legacy framebuffer (fbdev) text‑blitting code that could let a crafted character value cause an out‑of‑bounds read from the built‑in font table; the upstream fix clamps the computed...

A small but important Linux kernel hardening landed this month: the framebuffer console (fbcon) subsystem was patched to clear stale pointers by setting fb_display*->mode to NULL when a framebuffer mode is released, closing a use‑after‑free discovered by syzkaller that could otherwise allow a...

A small but important patch landed in the Linux kernel this week to stop a framebuffer text‑rendering routine from writing past its allocated vmalloc buffer — a classic bounds‑checking fix that removes a local denial‑of‑service and potential memory‑corruption vector. The upstream change to the...

When a Linux virtual machine runs on Microsoft Hyper‑V, the hyperv_fb framebuffer driver provides the synthetic display surface that makes console output and early-boot graphics available to the host and guest; a recent kernel fix for CVE-2025-21976 changes how that driver tears down its...

Hello to everyone. What I would like to understand if why,when I try to passthru my RTX 2080 ti from FreeBSD to Windows 11,it won't do it,causing the error 12. It says that it generates a resource conflict and requires additional installation). I'm trying to debug the error. Below you see the...
