Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
batman-adv: bla: prevent use-after-free when deleting claims<br />
<br />
When batadv_bla_del_backbone_claims() removes all claims for a backbone, it<br />
does this by dropping the link entry in the hash list. This list entry<br />
itself was one of the references which need to be dropped at the same time<br />
via batadv_claim_put().<br />
<br />
But the batadv_claim_put() must not be done before the last access to the<br />
claim object in this function. Otherwise the claim might be freed already<br />
by the batadv_claim_release() function before the list entry was dropped.
