Echo: linux: security update to 6.1.158-1

high Tenable Self-Hosted Container Security Plugin ID 459167

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: fix integer overflow in
 fbcon_do_set_font Fix integer overflow vulnerabilities in fbcon_do_set_font() where font size calculations
 could overflow when handling user-controlled font parameters. The vulnerabilities occur when: 1.
 CALC_FONTSZ(h, pitch, charcount) performs h * pith * charcount multiplication with user-controlled values
 that can overflow. 2. FONT_EXTRA_WORDS * sizeof(int) + size addition can also overflow 3. This results in
 smaller allocations than expected, leading to buffer overflows during font data copying. Add explicit
 overflow checking using check_mul_overflow() and check_add_overflow() kernel helpers to safety validate
 all size calculations before allocation. (CVE-2025-39967)

Solution

Update the linux library and its related packages to version 6.1.158-1 or later.
