Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: kernel (UTSA-2026-007406)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-007406 advisory. In the Linux kernel, the following vulnerability has been resolved: fbdev: Add bounds checking in bitputcs to fix vmalloc-out-of-bounds Add bounds checking to preven...

kernel: Linux kernel: Out-of-bounds write in fbdev can lead to privilege escalation, information disclosure, or denial of service.

A flaw was found in the Linux kernel, specifically within the framebuffer device fbdev subsystem. This vulnerability, an out-of-bounds write, occurs because the bitputcs function does not properly check boundaries when displaying text near the edges of the screen. A local user with low privileges...
