CVE-2022-50470: xhci: Remove device endpoints from bandwidth list when freeing the device

Noroxi assessment

Priority: Monitor (action score 31/100)

  • 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: 0.17% (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 3bf860a41e0f2fcea0ac3aae8f7ef887a7994b70, 5aed5b7c2430ce318a8e62f752f181e66f0d1053, 5e4ce28ad907aa54f13b21d5f1dc490525957b0c.

Low priority for now. Upgrade to Linux Linux 3bf860a41e0f2fcea0ac3aae8f7ef887a7994b70, 5aed5b7c2430ce318a8e62f752f181e66f0d1053, 5e4ce28ad907aa54f13b21d5f1dc490525957b0c or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: xhci: Remove device endpoints from bandwidth list when freeing the device Endpoints are normally deleted from the bandwidth list when they are dropped, before the virt device is freed. If xHC host is dying or being removed then the endpoints aren't dropped cleanly due to functions returning early to avoid interacting with a non-accessible host controller. So check and delete endpoints that are still on the bandwidth list when freeing the virt device. Solves a list_del corruption kernel crash when unbinding xhci-pci, caused by xhci_mem_cleanup() when it later tried to delete already freed endpoints from the bandwidth list. This only affects hosts that use software bandwidth checking, which currenty is only the xHC in intel Panther Point PCH (Ivy Bridge)
