CVE-2023-53003

In the Linux kernel, the following vulnerability has been resolved: EDAC/qcom: Do not pass llcc_driv_data as edac_device_ctl_info's pvt_info The memory for llcc_driv_data is allocated by the LLCC driver. But when it is passed as the private driver info to the EDAC core, it will get freed during the qcom_edac driver release. So when the qcom_edac driver gets probed again, it will try to use the freed data leading to the use-after-free bug. Hence, do not pass llcc_driv_data as pvt_info but rather reference it using the platform_data pointer in the qcom_edac driver.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: EDAC/qcom: No pasar llcc_driv_data como pvt_info de edac_device_ctl_info. El controlador LLCC asigna memoria para llcc_driv_data. Sin embargo, al pasarla como información privada del controlador al núcleo de EDAC, se libera durante la liberación del controlador qcom_edac. Por lo tanto, al volver a probar el controlador qcom_edac, intentará usar los datos liberados, lo que provoca el error de use-after-free. Por lo tanto, no pasar llcc_driv_data como pvt_info, sino referenciarlo mediante el puntero platform_data en el controlador qcom_edac.
