In the Linux kernel, the following vulnerability has been resolved:
RDMA/irdma: Fix kernel stack leak in irdma_create_user_ah()
struct irdma_create_ah_resp { // 8 bytes, no padding
__u32 ah_id; // offset 0 - SET (uresp.ah_id = ah->sc_ah.ah_info.ah_idx)
__u8 rsvd[4]; // offset 4 - NEVER SET <- LEAK
};
rsvd[4]: 4 bytes of stack memory leaked unconditionally. Only ah_id is assigned before ib_respond_udata().
The reserved members of the structure were not zeroed.
