Description

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftables: exthdr: fix 4-byte stack OOB write If priv->len is a multiple of 4, then dst[len / 4] can write past the destination array which leads to stack corruption. This construct is necessary to clean the remainder of the register in case ->len is NOT a multiple of the register size, so make it conditional just like nft_payload.c does. The bug was added in 4.1 cycle and then copied/inherited when tcp/sctp and ip option support was added. Bug reported by Zero Day Initiative project (ZDI-CAN-21950, ZDI-CAN-21951, ZDI-CAN-21961).

Affected configurations

• linux linux kernel (>= 4.1 < 5.10.198) • linux linux kernel (>= 5.11 < 5.15.132) • linux linux kernel (>= 5.16 < 6.1.54) • linux linux kernel (>= 6.2 < 6.5.4)
