phy: qcom: qmp-usb-legacy: fix NULL-deref on runtime suspend

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 29240130ab77c80bea1464317ae2a5fd29c16a0c, 7e8066811a2c43fbb5f53c2c26d389e4bab9da34, b1cffd00daa9cf499b49a0da698eff5032914f6e.

Low priority for now. Upgrade to Linux Linux 29240130ab77c80bea1464317ae2a5fd29c16a0c, 7e8066811a2c43fbb5f53c2c26d389e4bab9da34, b1cffd00daa9cf499b49a0da698eff5032914f6e or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: phy: qcom: qmp-usb-legacy: fix NULL-deref on runtime suspend Commit 413db06c05e7 ("phy: qcom-qmp-usb: clean up probe initialisation") removed most users of the platform device driver data from the qcom-qmp-usb driver, but mistakenly also removed the initialisation despite the data still being used in the runtime PM callbacks. This bug was later reproduced when the driver was copied to create the qmp-usb-legacy driver. Restore the driver data initialisation at probe to avoid a NULL-pointer dereference on runtime suspend. Apparently no one uses runtime PM, which currently needs to be enabled manually through sysfs, with these drivers.
