Descriptions
In the Linux kernel, the following vulnerability has been resolved: crypto: sun8i-ss - Fix memory leak of object d when dma_iv fails to map In the case where the dma_iv mapping fails, the return error path leaks
the memory allocated to object d. Fix this by adding a new error return
label and jumping to this to ensure d is free'd before the return. Addresses-Coverity: ("Resource leak")
En el kernel de Linux, se resolvió la siguiente vulnerabilidad: crypto: sun8i-ss: corrige la pérdida de memoria del objeto d cuando dma_iv no se puede asignar. En el caso de que falle la asignación de dma_iv, la ruta de error de retorno pierde la memoria asignada al objeto d. Solucione este problema agregando una nueva etiqueta de devolución de error y saltando a ella para asegurarse de que d esté libre antes de la devolución. Direcciones-Cobertura: ("Fuga de recursos")
