CVE-2023-52628 [HIGH] CWE-787 kernel: netfilter: nftables: exthdr: fix 4-byte stack OOB write
kernel: netfilter: nftables: exthdr: fix 4-byte stack OOB write
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).
An out-of-bounds write flaw was found in the Linux kernel’s Netfilter functionality. This flaw allows a local user to cr
