CVE-2026-74320 Detail

Description

In the Linux kernel, the following vulnerability has been resolved: fbdev: sm501fb: Fix buffer errors in OF binding code The code that gets the frame buffer mode from OF has 'use after free', 'buffer overrun' and memory leaks. info->edid_data isn't free if the probe functions fail or if pd->def_mode is set. If both the CRT and PANEL are enabled info->edid_data is used after being freed and is freed twice. The string returned by of_get_property(np, "mode", &len) is just written over either the static "640x480-16@60" or the module parameter string without any regard for the length (which is most likely longer). Use kstrump() for the OF mode and free everything before freeing 'info.
