Description OSIDB Bzimport 2025-01-15 14:02:17 UTC
In the Linux kernel, the following vulnerability has been resolved:

drm: adv7511: Fix use-after-free in adv7533_attach_dsi()

The host_node pointer was assigned and freed in adv7533_parse_dt(), and
later, adv7533_attach_dsi() uses the same. Fix this use-after-free issue
by dropping of_node_put() in adv7533_parse_dt() and calling of_node_put()
in error path of probe() and also in the remove().
