CVE-2024-50251

CVE-2024-50251 is a Linux kernel netfilter nft_payload vulnerability. The issue arises when nft_payload sanitization of offset and length fails, allowing skb_checksum() to access beyond the sk_buff boundary if offset+length exceeds the skb length, triggering a BUG_ON(). Connected advisories confi...

CVE-2024-50251 netfilter: nft_payload: sanitize offset and length before calling skb_checksum()

In the Linux kernel, the following vulnerability has been resolved: netfilter: nftpayload: sanitize offset and length before calling skbchecksum If access to offset + length is larger than the skbuff length, then skbchecksum triggers BUGON. skbchecksum internally subtracts the length parameter...

CVE-2024-47685

In the Linux kernel, CVE-2024-47685 patches nf_reject_ipv6: nf_reject_ip6_tcphdr_put() could push garbage into the four reserved TCP bits (th->res1) per KMSAN. The fix clears the entire TCP header using skb_put_zero(), aligning with nf_reject_ip_tcphdr_put(). Connected Astra Linux bulletin rep...
