  3. CVE-2022-49819
In the Linux kernel, the following vulnerability has been resolved: octeon_ep: fix potential memory leak in octep_device_setup() When occur unsupported_dev and mbox init errors, it did not free oct->conf and iounmap() oct->mmio[i].hw_addr. That would trigger memory leak problem. Add kfree() for oct->conf and iounmap() for oct->mmio[i].hw_addr under unsupported_dev and mbox init errors to fix the problem.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: octeon_ep: se corrige una posible fuga de memoria en octep_device_setup(). Cuando se producen errores unsupported_dev e init de mbox, no se liberan oct->conf ni iounmap() de oct->mmio[i].hw_addr. Esto causaría un problema de fuga de memoria. Se añaden kfree() para oct->conf e iounmap() para oct->mmio[i].hw_addr en los errores unsupported_dev e init de mbox para solucionar el problema.
