CVE-2023-52628

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).
