In the Linux kernel, the following vulnerability has been resolved:<\/p>\n
vhost-scsi: Validate T10 PI scatterlist counts<\/p>\n
When T10 PI is negotiated, vhost-scsi splits protection bytes from
\nthe data iterator before mapping the request scatterlists. A malformed
\nrequest can claim protection bytes that cover or exceed the full payload
\nlength. The former leaves no data bytes to map, while the latter
\nunderflows exp_data_len before advancing the iterator. Both cases can let
\na zero data SGL count reach sg_alloc_table_chained(), which triggers
\nBUG_ON(!nents).<\/p>\n
Reject protection lengths that cover or exceed the payload before
\nsubtracting prot_bytes and advancing the iterator. Also propagate
\nnegative errors from the protection SGL calculation before calling the
\nallocator, matching the data SGL path.<\/p>\n","protected":false},"excerpt":{"rendered":"
