CVE-2026-46191

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> fbcon: Avoid OOB font access if console rotation fails<br /> <br /> Clear the font buffer if the reallocation during console rotation fails<br /> in fbcon_rotate_font(). The putcs implementations for the rotated buffer<br /> will return early in this case. See [1] for an example.<br /> <br /> Currently, fbcon_rotate_font() keeps the old buffer, which is too small<br /> for the rotated font. Printing to the rotated console with a high-enough<br /> character code will overflow the font buffer.<br /> <br /> v2:<br /> - fix typos in commit message
