CVE-2020-36781

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2020-36781
In the Linux kernel, the following vulnerability has been resolved: i2c: imx: fix reference leak when pm_runtime_get_sync fails In i2c_imx_xfer() and i2c_imx_remove(), the pm reference count is not expected to be incremented on return. However, pm_runtime_get_sync will increment pm reference count even failed. Forgetting to putting operation will result in a reference leak here. Replace it with pm_runtime_resume_and_get to keep usage counter balanced.

Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: i2c: imx: corrige la fuga de referencia cuando falla pm_runtime_get_sync En i2c_imx_xfer() y i2c_imx_remove(), no se espera que el recuento de referencias pm aumente al regresar. Sin embargo, pm_runtime_get_sync incrementará el recuento de referencias de pm incluso si falla. Olvidarse de poner en funcionamiento resultará en una fuga de referencia aquí. Reemplácelo con pm_runtime_resume_and_get para mantener el contador de uso equilibrado.
