CVE-2022-50780 net: fix UAF issue in nfqnl_nf_hook_drop() when ops_init() failed

In the Linux kernel, the following vulnerability has been resolved: net: fix UAF issue in nfqnlnfhookdrop when opsinit failed When the opsinit interface is invoked to initialize the net, but ops-init fails, data is released. However, the ptr pointer in net-gen is invalid. In this case, when...

CVE-2022-50780

In CVE-2022-50780, the Linux kernel exposes a use-after-free (UAF) in nfqnl_nf_hook_drop() when ops_init() fails during net namespace setup. The allocation path kzalloc data is freed, but net->gen.ptr remains invalid, leading nfqnl_nf_hook_drop() to read a freed address (observed as a UAF in t...

CVE-2023-54051

CVE-2023-54051: In the Linux kernel, a missing check in virtio_net_hdr_to_skb() allowed gso_size to be set to GSO_BY_FRAGS (0xffff), which is a kernel magic value. This could lead to a general protection fault/NULL dereference in GSO/UDP offload paths (e.g., udp6_ufo_fragment, ipv6_gso_segment, s...
