xhci: Fix Panther point NULL pointer deref at full-speed re-enumeration

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: 0.25% (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 0f0654318e25b2c185e245ba4a591e42fabb5e59, 365ef7c4277fdd781a695c3553fa157d622d805d, 5ad898ae82412f8a689d59829804bff2999dd0ea.

Low priority for now. Upgrade to Linux Linux 0f0654318e25b2c185e245ba4a591e42fabb5e59, 365ef7c4277fdd781a695c3553fa157d622d805d, 5ad898ae82412f8a689d59829804bff2999dd0ea or later.

In the Linux kernel, the following vulnerability has been resolved: xhci: Fix Panther point NULL pointer deref at full-speed re-enumeration re-enumerating full-speed devices after a failed address device command can trigger a NULL pointer dereference. Full-speed devices may need to reconfigure the endpoint 0 Max Packet Size value during enumeration. Usb core calls usb_ep0_reinit() in this case, which ends up calling xhci_configure_endpoint(). On Panther point xHC the xhci_configure_endpoint() function will additionally check and reserve bandwidth in software. Other hosts do this in hardware If xHC address device command fails then a new xhci_virt_device structure is allocated as part of re-enabling the slot, but the bandwidth table pointers are not set up properly here. This triggers the NULL pointer dereference the next time usb_ep0_reinit() is called and xhci_configure_endpoint() tries to check and reserve bandwidth [46710.713538] usb 3-1: new full-speed USB device number 5 using xhci_hcd [46710.713699] usb 3-1: Device not responding to setup address.
