Echo: linux: security update to 6.12.63-1

medium Tenable Self-Hosted Container Security Plugin ID 465331

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: drm, fbcon, vga_switcheroo: Avoid race
 condition in fbcon setup Protect vga_switcheroo_client_fb_set() with console lock. Avoids OOB access in
 fbcon_remap_all(). Without holding the console lock the call races with switching outputs. VGA switcheroo
 calls fbcon_remap_all() when switching clients. The fbcon function uses struct fb_info.node, which is set
 by register_framebuffer(). As the fb-helper code currently sets up VGA switcheroo before registering the
 framebuffer, the value of node is -1 and therefore not a legal value. For example, fbcon uses the value
 within set_con2fb_map() [1] as an index into an array. Moving vga_switcheroo_client_fb_set() after
 register_framebuffer() can result in VGA switching that does not switch fbcon correctly. Therefore move
 vga_switcheroo_client_fb_set() under fbcon_fb_registered(), which already holds the console lock. Fbdev
 calls fbcon_fb_registered() from within register_framebuffer(). Serializes the helper with VGA
 switcheroo's call to fbcon_remap_all(). Although vga_switcheroo_client_fb_set() takes an instance of
 struct fb_info as parameter, it really only needs the contained fbcon state. Moving the call to fbcon
 initialization is therefore cleaner than before. Only amdgpu, i915, nouveau and radeon support
 vga_switcheroo. For all other drivers, this change does nothing. (CVE-2025-68296)

Solution

Update the linux library and its related packages to version 6.12.63-1 or later.
