Echo: linux: security update to 6.1.176-1

medium Tenable Cloud Security Plugin ID 463046

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/amdgpu: Limit BO list entry count
 to prevent resource exhaustion Userspace can pass an arbitrary number of BO list entries via the bo_number
 field. Although the previous multiplication overflow check prevents out-of-bounds allocation, a large
 number of entries could still cause excessive memory allocation (up to potentially gigabytes) and
 unnecessarily long list processing times. Introduce a hard limit of 128k entries per BO list, which is
 more than sufficient for any realistic use case (e.g., a single list containing all buffers in a large
 scene). This prevents memory exhaustion attacks and ensures predictable performance. Return -EINVAL if the
 requested entry count exceeds the limit (cherry picked from commit
 688b87d39e0aa8135105b40dc167d74b5ada5332) (CVE-2026-23468)

Solution

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