CVE-2024-47750

In the Linux kernel, the following vulnerability has been resolved: RDMA/hns: Fix Use-After-Free of rsv_qp on HIP08 Currently rsv_qp is freed before ib_unregister_device() is called on HIP08. During the time interval, users can still dereg MR and rsv_qp will be used in this process, leading to a UAF. Move the release of rsv_qp after calling ib_unregister_device() to fix it.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: RDMA/hns: Se corrige el use after free de rsv_qp en HIP08 Actualmente, rsv_qp se libera antes de que se llame a ib_unregister_device() en HIP08. Durante el intervalo de tiempo, los usuarios aún pueden anular la regulación de MR y rsv_qp se usará en este proceso, lo que genera un UAF. Mueva la liberación de rsv_qp después de llamar a ib_unregister_device() para solucionarlo.
