  2. Vulnerabilities (CVE)
  3. CVE-2020-36778
In the Linux kernel, the following vulnerability has been resolved: i2c: xiic: fix reference leak when pm_runtime_get_sync fails The PM reference count is not expected to be incremented on return in xiic_xfer and xiic_i2c_remove. However, pm_runtime_get_sync will increment the 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: xiic: corrige la fuga de referencia cuando falla pm_runtime_get_sync No se espera que el recuento de referencias de PM aumente al regresar en xiic_xfer y xiic_i2c_remove. 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.
