CVE-2024-50076

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

vt: prevent kernel-infoleak in con_font_get()

font.data may not initialize all memory spaces depending on the implementation of vc->vc_sw->con_font_get. This may cause info-leak, so to prevent this, it is safest to modify it to initialize the allocated memory space to 0, and it generally does not affect the overall performance of the system.

Weakness

The product does not initialize a critical resource.
