What to Know

In the Linux kernel, the following vulnerability has been resolved:

scsi: qla2xxx: Null out freed pointers in qla2x00_mem_alloc() error path

When qla2x00_mem_alloc() fails, qla2x00_probe_one() jumps to

probe_hw_failed and calls qla2x00_mem_free(). Several error labels in

qla2x00_mem_alloc() freed adapter members (elsrej.c, purex_dma_pool,

flt, sfp_data, loop_id_map, async_pd, sf_init_cb, ex_init_cb, npiv_info)

but left the pointers dangling. qla2x00_mem_free() then freed them a

second time. Worse, for the dma_pool members it issued

dma_pool_free(ha->s_dma_pool, ...) after s_dma_pool had already been

destroyed and set to NULL at fail_s_dma_pool, dereferencing a NULL pool.

Clear each freed pointer (and its DMA handle) in the error labels so the

subsequent qla2x00_mem_free() skips them. (NVD)
