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

nvmet-tcp: add bounds checks in nvmet_tcp_build_pdu_iovec

nvmet_tcp_build_pdu_iovec() could walk past cmd->req.sg when a PDU
length or offset exceeds sg_cnt and then use bogus sg->length/offset
values, leading to _copy_to_iter() GPF/KASAN. Guard sg_idx, remaining
entries, and sg->length/offset before building the bvec.

Severity: 0.0 | NA
