Description

In the Linux kernel, the following vulnerability has been resolved:

bpf: Add sk_is_inet and IS_ICSK check in tls_sw_has_ctx_tx/rx

As the introduction of the support for vsock and unix sockets in sockmap,
tls_sw_has_ctx_tx/rx cannot presume the socket passed in must be IS_ICSK.
vsock and af_unix sockets have vsock_sock and unix_sock instead of
inet_connection_sock. For these sockets, tls_get_ctx may return an invalid
pointer and cause page fault in function tls_sw_ctx_rx.

BUG: unable to handle page fault for address: 0000000000040030
Workqueue: vsock-loopback vsock_loopback_work
RIP: 0010:sk_psock_strp_data_ready+0x23/0x60
