GHSA-82VQ-G77C-V2H9
Vulnerability from github – Published: 2024-10-29 03:31 – Updated: 2024-11-08 18:30In 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.
