Description Johannes Segitz 2017-12-06 09:50:06 UTC

CVE-2017-15868

The bnep_add_connection function in net/bluetooth/bnep/core.c in the Linux
kernel before 3.19 does not ensure that an l2cap socket is available, which
allows local users to gain privileges via a crafted application.

Comment 1 Miroslav Beneš 2017-12-07 14:19:46 UTC

FYI, there is upstream commit 96c26653ce65 ("Bluetooth: cmtp: cmtp_add_connection() should verify that it's dealing with l2cap socket") and it would be great to fix it as part of this bug too.

Yes, Thanks a lot.

I will push this two at the same time:
71bb99a02b32 Bluetooth: bnep: bnep_add_connection() should verify that it's dealing with l2cap socket (v3.19-rc3)
96c26653ce65 Bluetooth: cmtp: cmtp_add_connection() should verify that it's dealing with l2cap socket (v3.19-rc3)
