Echo: linux: security update to 6.1.170-1

high Tenable Self-Hosted Container Security Plugin ID 465228

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/exynos: vidi: use ctx->lock to
protect struct vidi_context member variables related to memory alloc/free Exynos Virtual Display driver
performs memory alloc/free operations without lock protection, which easily causes concurrency problem.
For example, use-after-free can occur in race scenario like this: ``` CPU0 CPU1 CPU2 ---- ---- ----
vidi_connection_ioctl() if (vidi->connection) // true drm_edid = drm_edid_alloc(); // alloc drm_edid ...
ctx->raw_edid = drm_edid; ... drm_mode_getconnector() drm_helper_probe_single_connector_modes()
vidi_get_modes() if (ctx->raw_edid) // true drm_edid_dup(ctx->raw_edid); if (!drm_edid) // false ...
vidi_connection_ioctl() if (vidi->connection) // false drm_edid_free(ctx->raw_edid); // free drm_edid ...
drm_edid_alloc(drm_edid->edid) kmemdup(edid); // UAF!! ... ``` To prevent these vulns, at least in
vidi_context, member variables related to memory alloc/free should be protected with ctx->lock.
(CVE-2026-23227)
