CVE-2022-49340 ip_gre: test csum_start instead of transport header

In the Linux kernel, the following vulnerability has been resolved: ipgre: test csumstart instead of transport header GRE with TUNNELCSUM will apply local checksum offload on CHECKSUMPARTIAL packets. ipgrexmit must validate csumstart after an optional skbpull, else lcocsum may trigger an overflow...

CVE-2024-49947

In the Linux kernel, the following vulnerability has been resolved: net: test for not too small csumstart in virtionethdrtoskb syzbot was able to trigger this warning 1, after injecting a malicious packet through afpacket, setting skb-csumstart and thus the transport header to an incorrect value...

CVE-2024-49947

CVE-2024-49947 affects the Linux kernel net stack, specifically a vulnerability in virtio_net_hdr_to_skb() where an incorrectly set skb->csum_start could place the transport header before or after the network header when processing injected packets via af_packet. Syzbot-triggered warnings show...

In the Linux kernel, the following vulnerability has been resolved: net: drop bad gso csumstart and offset in virtionethdr Tighten csumstart and csumoffset checks in virtionethdrtoskb for GSO packets. The function already checks that a checksum requested with VIRTIONETHDRFNEEDSCSUM is in skb...

CVE-2024-43897

The CVE-2024-43897 entry concerns the Linux kernel net/virtio_net_hdr handling for GSO. The fix tightens csum_start and csum_offset checks in virtio_net_hdr_to_skb for GSO packets, ensuring that a checksum requested via VIRTIO_NET_HDR_F_NEEDS_CSUM is valid in the skb after segmentation. The patch...
