The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: smc: Fix various oops due to inet_sock     type confusion. syzbot reported weird splats [0][1] in cipso_v4_sock_setattr() while freeing     inet_sk(sk)->inet_opt. The address was freed multiple times even though it was read-only memory.
    cipso_v4_sock_setattr() did nothing wrong, and the root cause was type confusion. The cited commit made it     possible to create smc_sock as an INET socket. The issue is that struct smc_sock does not have struct     inet_sock as the first member but hijacks AF_INET and AF_INET6 sk_family, which confuses various places.
    In this case, inet_sock.inet_opt was actually smc_sock.clcsk_data_ready(), which is an address of a     function in the text segment. $ pahole -C inet_sock vmlinux struct inet_sock { ... struct ip_options_rcu *     inet_opt; /* 784 8 */ $ pahole -C smc_sock vmlinux struct smc_sock { ... void (*clcsk_data_ready)(struct     sock *); /* 784 8 */ The same issue for another field was reported before. [2][3] At that time, an ugly     hack was suggested [4], but it makes both INET and SMC code error-prone and hard to change. Also, yet     another variant was fixed by a hacky commit 98d4435efcbf3 (net/smc: prevent NULL pointer dereference in     txopt_get). Instead of papering over the root cause by such hacks, we should not allow non-INET socket to     reuse the INET infra. Let's add inet_sock as the first member of smc_sock.
