Detailsinfo

A vulnerability classified as very critical has been found in Linux Kernel up to 7.2.5. This affects the function phy_create of the component snps-femto-v2. The manipulation with an unknown input leads to a null pointer dereference vulnerability. CWE is classifying the issue as CWE-476. A NULL pointer dereference occurs when the application dereferences a pointer that it expects to be valid, but is NULL, typically causing a crash or exit. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

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.

The advisory is shared at git.kernel.org. This vulnerability is uniquely identified as CVE-2026-90281 since 09/11/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. Technical details are known, but no exploit is available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 09/17/2026).

Upgrading to version 5.10.270, 5.15.221, 6.1.188, 6.6.157, 6.12.110, 6.18.52, 7.2.6 or 7.3-rc1 eliminates this vulnerability. Applying the patch 0c5c08c94dd64c05679970d4eed8b06d36a889a8/1027b1d4e29756dfbf74ef8743456a1efa3679f0/34293f5a8982a06c40af69c8c7c856b5837ac652/3ddf41938fee3d148a170c31e76b0515a522ef7e/82cb1aedf4bdb279cf8853fe8f39bec4e6cffa0a/61749681e4a3629ec20b04ba2443b91016af3d2f/b85bbec72fa813b60e093c6bb36ae232b9b0eb5e/c271a6926ea7d3c9566b033d63fd4e8c488dc860 is able to eliminate this problem. The best possible mitigation is suggested to be upgrading to the latest version.
