CVE-2025-39839

*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> batman-adv: fix OOB read/write in network-coding decode<br /> <br /> batadv_nc_skb_decode_packet() trusts coded_len and checks only against<br /> skb-&gt;len. XOR starts at sizeof(struct batadv_unicast_packet), reducing<br /> payload headroom, and the source skb length is not verified, allowing an<br /> out-of-bounds read and a small out-of-bounds write.<br /> <br /> Validate that coded_len fits within the payload area of both destination<br /> and source sk_buffs before XORing.
