CVE-2026-53261

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> devlink: Release nested relation on devlink free<br /> <br /> devlink relation state is normally released from devl_unregister(), which<br /> calls devlink_rel_put(). This misses devlink instances that get a nested<br /> relation before registration and then fail probe before devl_register() is<br /> reached.<br /> <br /> That flow can happen for SFs. The child devlink gets linked to its<br /> parent before registration, then a later probe error calls devlink_free()<br /> directly. Since the instance was never registered, devl_unregister() is not<br /> called and devlink-&gt;rel is leaked.<br /> <br /> Release any pending relation from devlink_free() as well. The registered<br /> path is unchanged because devl_unregister() already clears devlink-&gt;rel<br /> before devlink_free() runs.
