Summary
In the Linux kernel, the following vulnerability has been resolved: phy: qcom-qmp-usb: Fix an NULL vs IS_ERR() bug The qmp_usb_iomap() helper function currently returns the raw result of devm_ioremap() for non-exclusive mappings. Since devm_ioremap() may return a NULL pointer and the caller only checks error pointers with IS_ERR(), NULL could bypass the check and lead to an invalid dereference. Fix the issue by checking if devm_ioremap() returns NULL. When it does, qmp_usb_iomap() now returns an error pointer via IOMEM_ERR_PTR(-ENOMEM), ensuring safe and consistent error handling.

      "value": "En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: phy: qcom-qmp-usb: Se corrige un error de NULL frente a IS_ERR(). La funci\u00f3n auxiliar qmp_usb_iomap() actualmente devuelve el resultado sin procesar de devm_ioremap() para asignaciones no exclusivas. Dado que devm_ioremap() puede devolver un puntero NULL y el llamador solo comprueba los punteros de error con IS_ERR(), NULL podr\u00eda omitir la comprobaci\u00f3n y provocar una desreferencia no v\u00e1lida. Corrija el problema comprobando si devm_ioremap() devuelve NULL. Cuando lo hace, qmp_usb_iomap() ahora devuelve un puntero de error mediante IOMEM_ERR_PTR(-ENOMEM), lo que garantiza un manejo de errores seguro y consistente."
