This issue was patched in ELSA-2026-500374.
NVD Description
Note: Versions mentioned in the description apply only to the upstream kernel-uek package and not the kernel-uek package as distributed by Oracle.
See How to fix? for Oracle:10 relevant fixed versions and status.
In the Linux kernel, the following vulnerability has been resolved:
drm/gud: validate TV mode names before creating enum property
The GUD protocol returns TV mode names as fixed-size GUD_CONNECTOR_TV_MODE_NAME_LEN entries and requires each name to be NUL-terminated.
gud_connector_add_tv_mode() currently passes each fixed-size entry directly to drm_mode_create_tv_properties_legacy(), which eventually reaches drm_property_add_enum() and strlen(). If a device returns an entry without a terminating NUL byte, strlen() reads past the end of the slot and can run beyond the allocated buffer, triggering an out-of-bounds read.
Validate that each returned TV mode name contains a NUL terminator within its fixed-size slot before passing it to the DRM property code. If a malformed entry is found, reject the device response with -EIO.
This fixes the out-of-bounds read without changing the handling of valid devices, and avoids silently truncating malformed protocol data.
