Description

In the Linux kernel, the following vulnerability has been resolved: netfilter: nft_payload: sanitize offset and length before calling skb_checksum() If access to offset + length is larger than the skbuff length, then skb_checksum() triggers BUG_ON(). skb_checksum() internally subtracts the length parameter while iterating over skbuff, BUG_ON(len) at the end of it checks that the expected length to be included in the checksum calculation is fully consumed.

Affected configurations

• linux linux kernel (>= 4.5 < 4.19.323) • linux linux kernel (>= 4.20 < 5.4.285) • linux linux kernel (>= 5.5 < 5.10.229) • linux linux kernel (>= 5.11 < 5.15.171) • linux linux kernel (>= 5.16 < 6.1.116) • linux linux kernel (>= 6.2 < 6.6.60) • linux linux kernel (>= 6.7 < 6.11.7) • linux linux kernel 6.12
