Echo: linux: security update to 6.1.159-1

high Tenable Cloud Security Plugin ID 462167

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: fbdev: Add bounds checking in
 bit_putcs to fix vmalloc-out-of-bounds Add bounds checking to prevent writes past framebuffer boundaries
 when rendering text near screen edges. Return early if the Y position is off-screen and clip image height
 to screen boundary. Break from the rendering loop if the X position is off-screen. When clipping image
 width to fit the screen, update the character count to match the clipped width to prevent buffer size
 mismatches. Without the character count update, bit_putcs_aligned and bit_putcs_unaligned receive
 mismatched parameters where the buffer is allocated for the clipped width but cnt reflects the original
 larger count, causing out-of-bounds writes. (CVE-2025-40304)

Solution

Update the linux library and its related packages to version 6.1.159-1 or later.
