Summary
  • (es) En el kernel de Linux, se resolvió la siguiente vulnerabilidad: scsi: target: pscsi: corrige bio_put() para el caso de error A partir del commit 066ff571011d ("bloque: convierte bio_kmalloc en un contenedor kmalloc simple"), una biografía asignada por bio_kmalloc() debe ser liberado por bio_uninit() y kfree(). Esto no se hace correctamente en el caso de error, al presionar WARN y desreferenciar el puntero NULL en bio_free().
