high Tenable Cloud Security Plugin ID 455627

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: fbcon: Avoid OOB font access if
 console rotation fails Clear the font buffer if the reallocation during console rotation fails in
 fbcon_rotate_font(). The putcs implementations for the rotated buffer will return early in this case. See
 [1] for an example. Currently, fbcon_rotate_font() keeps the old buffer, which is too small for the
 rotated font. Printing to the rotated console with a high-enough character code will overflow the font
 buffer. v2: - fix typos in commit message (CVE-2026-46191)

Solution

Update the linux library and its related packages to version 6.1.176-1 or later.
