Descriptions

In the Linux kernel, the following vulnerability has been resolved:

IB/hfi1: Fix a memleak in init_credit_return

When dma_alloc_coherent fails to allocate dd->cr_base[i].va,
init_credit_return should deallocate dd->cr_base and
dd->cr_base[i] that allocated before. Or those resources
would be never freed and a memleak is triggered.

En el kernel de Linux, se resolvió la siguiente vulnerabilidad: IB/hfi1: corrige una fuga de mem en init_credit_return Cuando dma_alloc_coherent no puede asignar dd->cr_base[i].va, init_credit_return debería desasignar dd->cr_base y dd->cr_base[i]. ] el asignado antes. O esos recursos nunca se liberarían y se desencadenaría una fuga de memoria.
