Descripción

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> batman-adv: stop caching unowned originator pointers in BAT IV<br /> <br /> BAT IV keeps the last-hop neighbor address in each neigh_node, but some<br /> paths also cache an originator pointer derived from a temporary lookup.<br /> That pointer is not owned by the neigh_node and may no longer refer to a<br /> live originator entry after purge handling runs.<br /> <br /> Stop storing the auxiliary originator pointer in the BAT IV neighbor<br /> state. When BAT IV needs the neighbor originator data, resolve it from<br /> the stored neighbor address and drop the reference again after use.<br /> <br /> [sven: avoid bonding logic for outgoing OGM]
