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.

Affected configurations

• linux linux kernel (>= 5.0 < 5.10.250) • linux linux kernel (>= 5.11 < 5.15.200) • linux linux kernel (>= 5.16 < 6.1.163) • linux linux kernel (>= 6.2 < 6.6.124) • linux linux kernel (>= 6.7 < 6.12.70) • linux linux kernel (>= 6.13 < 6.18.10) • linux linux kernel 6.19
