TIMELINE Apr 16 Reserved by Linux Sep 19 Published (CNA: Linux) Jul 30 RESCORED — CVE-2025-39839 (Linux). CVSS 8.8 → 7.1 (NVD).
In the Linux kernel, the following vulnerability has been resolved: batman-adv: fix OOB read/write in network-coding decode batadv_nc_skb_decode_packet() trusts coded_len and checks only against skb->len. XOR starts at sizeof(struct batadv_unicast_packet), reducing payload headroom, and the source skb length is not verified, allowing an out-of-bounds read and a small out-of-bounds write. Validate that coded_len fits within the payload area of both destination and source sk_buffs before XORing.
