We leak in drivers/scsi/aacraid/commctrl.c::aac_send_raw_srb() :
We allocate memory:
...
struct user_sgmap* usg;
usg = kmalloc(actual_fibsize - sizeof(struct aac_srb)
+ sizeof(struct sgmap), GFP_KERNEL);
and then neglect to free it:
...
for (i = 0; i < usg->count; i++) {
u64 addr;
void* p;
if (usg->sg[i].count >
((dev->adapter_info.options &
AAC_OPT_NEW_COMM) ?
(dev->scsi_host_ptr->max_sectors << 9) :
65536)) {
rcode = -EINVAL;
goto cleanup;
... this 'goto' makes 'usg' go out of scope and leak the memory we
allocated.
Other exits properly kfree(usg), it's just here it is neglected.
