CVE-2024-58009: Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc

Noroxi assessment

Priority: Monitor (action score 22/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.20% (FIRST EPSS).
  • Someone with local access to the system can trigger it. A low-privileged account is enough. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: Linux Linux 245d48c1ba3e7a1779c2f4cbc6f581ddc8a78e22, 297ce7f544aa675b0d136d788cad0710cdfb0785, 49c0d55d59662430f1829ae85b969619573d0fa1.

Low priority for now. Upgrade to Linux Linux 245d48c1ba3e7a1779c2f4cbc6f581ddc8a78e22, 297ce7f544aa675b0d136d788cad0710cdfb0785, 49c0d55d59662430f1829ae85b969619573d0fa1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: L2CAP: handle NULL sock pointer in l2cap_sock_alloc A NULL sock pointer is passed into l2cap_sock_alloc() when it is called from l2cap_sock_new_connection_cb() and the error handling paths should also be aware of it. Seemingly a more elegant solution would be to swap bt_sock_alloc() and l2cap_chan_create() calls since they are not interdependent to that moment but then l2cap_chan_create() adds the soon to be deallocated and still dummy-initialized channel to the global list accessible by many L2CAP paths. The channel would be removed from the list in short period of time but be a bit more straight-forward here and just check for NULL instead of changing the order of function calls. Found by Linux Verification Center (linuxtesting.org) with SVACE static analysis tool.
