# CVE-2026-72272: fbdev: radeon: fix potential memory leak in radeonfb_pci_register()

Status: published. Published: 2026-08-15. Updated: 2026-11-06.

In the Linux kernel, the following vulnerability has been resolved:

fbdev: radeon: fix potential memory leak in radeonfb_pci_register()

The function radeonfb_pci_register() allocates memory for modelist
(by calling radeon_check_modes() which calls fb_add_videomode()).
The memory is appended to info->modelist, but is not freed in subsequent
error paths. Fix this by calling fb_destroy_modelist().
