drm/exynos: vidi: use ctx->lock to protect struct vidi_context member variables related to memory alloc/free

2026-02-16T09:13:34+00:00

commit 52b330799e2d6f825ae2bb74662ec1b10eb954bb upstream. 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.

drm/xe/guc: Fix CFI violation in debugfs access.

2026-02-05T08:45:22+00:00

xe_guc_print_info is void-returning, but the function pointer it is assigned to expects an int-returning function, leading to the following CFI error: [ 206.873690] CFI failure at guc_debugfs_show+0xa1/0xf0 [xe] (target: xe_guc_print_info+0x0/0x370 [xe]; expected type: 0xbe3bc66a) Fix this by updating xe_guc_print_info to return an integer.

drm/bridge: imx8mp-hdmi-pai: enable PM runtime

2026-02-05T08:16:45+00:00

There is an audio channel shift issue with multi channel case - the channel order is correct for the first run, but the channel order is shifted for the second run. The fix method is to reset the PAI interface at the end of playback. The reset can be handled by PM runtime, so enable PM runtime.
