CVE-2026-90296: cpufreq: imx6q: fix devres accumulation across driver rebind

Noroxi assessment

Priority: Monitor (action score 0/100)

  • 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: 0.22% (FIRST EPSS).
  • Fixed version: Linux Linux 0f77d1a0a25056146eea1f8619fa06ce287c91f7, 22c23c72c3b21fa3ec3db5070dfc0582794e0ef9, 38d2c3c9238b9d499e1829a3b8e80c2f73c73b5c.

Low priority for now. Upgrade to Linux Linux 0f77d1a0a25056146eea1f8619fa06ce287c91f7, 22c23c72c3b21fa3ec3db5070dfc0582794e0ef9, 38d2c3c9238b9d499e1829a3b8e80c2f73c73b5c or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: cpufreq: imx6q: fix devres accumulation across driver rebind imx6_soc_volt is allocated with devm_kcalloc(cpu_dev, ...), where cpu_dev is the CPU device from get_cpu_device(0). That device is never unbound, so its devres list is never released, and imx6q_cpufreq_remove() does not free the array either. Every probe therefore adds an allocation that stays for the lifetime of the system. Allocate against the platform device instead. Its devres is released when the driver is unbound, which is exactly the lifetime the array wants: imx6q_set_target() reads it, and nothing may reach that after cpufreq_unregister_driver(). That makes the array actually go away on unbind, so also clear the file-scope pointer in remove and on the failed-probe path, rather than leave it pointing at memory devres is about to release. Tested by rebinding the driver on qemu's mcimx6ul-evk.
