  3. CVE-2023-52888
In the Linux kernel, the following vulnerability has been resolved: media: mediatek: vcodec: Only free buffer VA that is not NULL In the MediaTek vcodec driver, while mtk_vcodec_mem_free() is mostly called only when the buffer to free exists, there are some instances that didn't do the check and triggered warnings in practice. We believe those checks were forgotten unintentionally. Add the checks back to fix the warnings.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: media: mediatek: vcodec: Solo libera el búfer VA que no es NULL En el controlador MediaTek vcodec, mientras que mtk_vcodec_mem_free() se llama principalmente solo cuando el búfer a liberar existe, hay algunas casos que no hicieron la verificación y activaron advertencias en la práctica. Creemos que esos cheques se olvidaron sin querer. Vuelva a agregar las comprobaciones para corregir las advertencias.
