Details

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 Call Trace: ? __die+0x81/0xc3 ? no_context+0x194/0x350 ? do_page_fault+0x30/0x110 ? async_page_fault+0x3e/0x50 ? sk_psock_strp_data_ready+0x23/0x60 virtio_transport_recv_pkt+0x750/0x800 ? update_load_avg+0x7e/0x620 vsock_loopback_work+0xd0/0x100 process_one_work+0x1a7/0x360 worker_thread+0x30/0x390 ? create_worker+0x1a0/0x1a0 kthread+0x112/0x130 ? __kthread_cancel_work+0x40/0x40 ret_from_fork+0x1f/0x40

v2: - Add IS_ICSK check v3: - Update the commits in Fixes
