Echo: linux: security update to 6.1.176-1

medium Tenable Self-Hosted Container Security Plugin ID 457317

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/sdma4: replace BUG_ON with
WARN_ON in fence emission sdma_v4_0_ring_emit_fence() contains two BUG_ON(addr & 0x3) assertions that
verify fence writeback addresses are dword-aligned. These assertions can be reached from unprivileged
userspace via crafted DRM_IOCTL_AMDGPU_CS submissions, causing a fatal kernel panic in a scheduler worker
thread. Replace both BUG_ON() calls with WARN_ON() to log the condition without crashing the kernel. A
misaligned fence address at this point indicates a driver bug, but crashing the kernel is never the
correct response when the assertion is reachable from userspace. The CS IOCTL path is the correct place to
filter invalid submissions; the ring emission callback is too late to do anything about it. (cherry picked
from commit b90250bd933afd1ba94d86d6b13821997b22b18e) (CVE-2026-46220)

Solution
