  "details": "In the Linux kernel, the following vulnerability has been resolved:  RDMA/rxe: Fix double free in rxe_srq_from_init  In rxe_srq_from_init(), the queue pointer 'q' is assigned to 'srq-\u003erq.queue' before copying the SRQ number to user space. If copy_to_user() fails, the function calls rxe_queue_cleanup() to free the queue, but leaves the now-invalid pointer in 'srq-\u003erq.queue'.  The caller of rxe_srq_from_init() (rxe_create_srq) eventually calls rxe_srq_cleanup() upon receiving the error, which triggers a second rxe_queue_cleanup() on the same memory, leading to a double free.  The call trace looks like this:    kmem_cache_free+0x.../0x...    rxe_queue_cleanup+0x1a/0x30 [rdma_rxe]    rxe_srq_cleanup+0x42/0x60 [rdma_rxe]    rxe_elem_release+0x31/0x70 [rdma_rxe]    rxe_create_srq+0x12b/0x1a0 [rdma_rxe]    ib_create_srq_user+0x9a/0x150 [ib_core]  Fix this by moving 'srq-\u003erq.queue = q' after copy_to_user.",
