Hi Alexander, I enjoyed reading your blog entries for CVE-2017-2636 and CVE-2019-18683. https://lore.kernel.org/lkml/20210201084719.2257066-1-alex.popov@xxxxxxxxx/ My understanding is that you were able to write a privilege escalataion bug for this? Are you going to do a write up for this one as well? Was the trick to exploiting it to use the free in vsock_deassign_transport()? I've wanted to look for these in Smatch (my static analysis tool) for a long time. I wrote a very naive first draft implementation. What it looks for is when we access struct sock members before calling lock_sock(). It generated 8 warnings. Six were false positives but I think that two were probably real bugs. net/nfc/llcp_sock.c:313 nfc_llcp_getsockopt() warn: unlocked access 'llcp_sock->local' expected lock '&sk->sk_lock.slock' net/nfc/llcp_sock.c:597 llcp_sock_release() warn: unlocked access 'llcp_sock->local' expected lock '&sk->sk_lock.slock' But I think it would be hard to exploit those because the race is very tiny. Several people (maybe most recently Lukas Bulwahn but someone else at Linux Plumbers) suggested that a way to find race conditions is to look at the line directly after taking a lock. So if you have: mutex_lock(&dsp->pwr_lock); if (!dsp->wmfw_file_name || !dsp->booted) Then that means that the ->pwr_lock is protecting ->wmfw_file_name and ->booted. So I wrote a check that made a list of these sorts of pairings. Then I wrote a check that said: If you take save a "protected" struct member and then take the lock print a warning that the access should have been inside the lock. So a warning looks like this: sound/pci/cs46xx/cs46xx_lib.c:2148 snd_cs46xx_spdif_default_get() warn: unlocked access 'ins' (line 2146) expected lock '&chip->spos_mutex' 2142 static int snd_cs46xx_spdif_default_get(struct snd_kcontrol *kcontrol, 2143 struct snd_ctl_elem_value *ucontrol) 2144 { 2145 struct snd_cs46xx *chip = snd_kcontrol_chip(kcontrol); 2146 struct dsp_spos_instance * ins = chip->dsp_spos_instance; ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Smatch is saying this assignment should have been done 2147 2148 mutex_lock(&chip->spos_mutex); ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ inside this lock. 2149 ucontrol->value.iec958.status[0] = _wrap_all_bits((ins->spdif_csuv_default >> 24) & 0xff); 2150 ucontrol->value.iec958.status[1] = _wrap_all_bits((ins->spdif_csuv_default >> 16) & 0xff); 2151 ucontrol->value.iec958.status[2] = 0; 2152 ucontrol->value.iec958.status[3] = _wrap_all_bits((ins->spdif_csuv_default) & 0xff); 2153 mutex_unlock(&chip->spos_mutex); 2154 2155 return 0; 2156 } That seems probably true but also a pretty harmless. I've attached a sample of the output just in case you're curious. Do you have any idea how I could get more worthwhile results than this? regards, dan carpenter
