[PATCH] coverity: i386: scsi_lib buffer overrun fix
The check in
627 BUG_ON(index > SG_MEMPOOL_NR);
with SG_MEMPOOL_NR defined in
32 #define SG_MEMPOOL_NR (sizeof(scsi_sg_pools)/sizeof(struct scsi_host_sg_pool))
was not sufficient.
sgp, set in
629 sgp = scsi_sg_pools + index;
is dereferenced in
630 mempool_free(sgl, sgp->pool);
