Description OSIDB Bzimport 2024-12-29 12:01:45 UTC 
In the Linux kernel, the following vulnerability has been resolved:

scsi: qedi: Fix a possible memory leak in qedi_alloc_and_init_sb()

Hook "qedi_ops->common->sb_init = qed_sb_init" does not release the DMA
memory sb_virt when it fails. Add dma_free_coherent() to free it. This
is the same way as qedr_alloc_mem_sb() and qede_alloc_mem_sb().
