- Summary
- batman-adv: fix OOB read/write in network-coding decode
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
batman-adv: fix OOB read/write in network-coding decode
batadvncskbdecodepacket() trusts codedlen and checks only against skb->len. XOR starts at sizeof(struct batadvunicast_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 codedlen fits within the payload area of both destination and source skbuffs before XORing.
