CVE-2026-90281: phy: qcom: snps-femto-v2: Fix possible NULL-deref on early runtime suspend

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: 0.21% (FIRST EPSS).
  • Fixed version: Linux Linux 0c5c08c94dd64c05679970d4eed8b06d36a889a8, 1027b1d4e29756dfbf74ef8743456a1efa3679f0, 34293f5a8982a06c40af69c8c7c856b5837ac652; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 6.6.157.1-1.

Low priority for now. Upgrade to Linux Linux 0c5c08c94dd64c05679970d4eed8b06d36a889a8, 1027b1d4e29756dfbf74ef8743456a1efa3679f0, 34293f5a8982a06c40af69c8c7c856b5837ac652; azl3 kernel 6.6.152.1-1 on Azure Linux 3.0 6.6.157.1-1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

In the Linux kernel, the following vulnerability has been resolved: phy: qcom: snps-femto-v2: Fix possible NULL-deref on early runtime suspend Runtime PM must be enabled before creating the PHY, since phy_create() only enables runtime PM on the PHY device if it is already enabled on this parent device. However, the runtime PM callbacks dereference the hsphy instance, which is not yet ready, leaving a window where a suspend callback may trigger a NULL pointer dereference. Take a runtime PM usage reference with pm_runtime_get_noresume() before enabling runtime PM and release it once the PHY has been created, so that no runtime suspend can run before the PHY is ready. This also prevents a short window where an unnecessary runtime suspend can occur. Use the devres-managed version to ensure PM runtime is symmetrically disabled during driver removal for proper cleanup.
