CVE-2026-74424

CVE-2026-74424 affects the Linux kernel framebuffer console driver (fbcon). The issue arises when fbcon_new_modelist() iterates consoles with fb_display[i].mode set; it can dereference a NULL vc_data because fbcon_set_disp() may set mode before validating vc_data, and fbcon_deinit() can leave the...

AZL-92525 CVE-2026-53402 affecting package kernel for versions less than 6.6.145.2-1

In the Linux kernel, the following vulnerability has been resolved: fbdev: fbcon: fix out-of-bounds read in errout of fbcondosetfont When fbcondosetfont fails e.g., due to a memory allocation failure inside vcresize under heavy memory pressure, it jumps to the errout label to roll back the consol...

CVE-2026-63826

The CVE-2026-63826 issue affects the Linux kernel fbdev path, where store_modes() frees a framebuffer modelist but leaves stale pointers in fb_display[i].mode and fb_info->mode. The root cause is use-after-free reads when fbcon_mode_deleted() and show_mode() dereference these pointers after fb...

CVE-2026-53403

The CVE-2026-53403 issue is a Linux kernel framebuffer (fbdev) risk fixed by correcting fb_new_modelist to preserve the current mode in info->var when the modelist is replaced. Root cause: info->var must have a matching entry in info->modelist; if store_modes() or fb_new_modelist() chang...
