In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
drm\/gud: validate TV mode names before creating enum property<\/p>\n
The GUD protocol returns TV mode names as fixed-size
\nGUD_CONNECTOR_TV_MODE_NAME_LEN entries and requires each name to be
\nNUL-terminated.<\/p>\n
gud_connector_add_tv_mode() currently passes each fixed-size entry
\ndirectly to drm_mode_create_tv_properties_legacy(), which eventually
\nreaches drm_property_add_enum() and strlen(). If a device returns an
\nentry without a terminating NUL byte, strlen() reads past the end of
\nthe slot and can run beyond the allocated buffer, triggering an
\nout-of-bounds read.<\/p>\n
Validate that each returned TV mode name contains a NUL terminator
\nwithin its fixed-size slot before passing it to the DRM property code.
\nIf a malformed entry is found, reject the device response with -EIO.<\/p>\n
This fixes the out-of-bounds read without changing the handling of
\nvalid devices, and avoids silently truncating malformed protocol data.<\/p>\n","protected":false},"excerpt":{"rendered":"
