UBUNTU-CVE-2026-23112: Critical severity ubuntu/linux-hwe-edge vulnerability

Published Feb 13, 2026

Updated

In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: add bounds checks in nvmettcpbuildpduiovec nvmettcpbuildpduiovec() could walk past cmd->req.sg when a PDU length or offset exceeds sgcnt and then use bogus sg->length/offset values, leading to copytoiter() GPF/KASAN. Guard sgidx, remaining entries, and sg->length/offset before building the bvec.

Frequently Asked Questions

Which Ubuntu kernel package families are affected?

The affected software list includes ubuntu/linux, ubuntu/linux-azure, ubuntu/linux-gcp, ubuntu/linux-aws-fips, ubuntu/linux-azure-fips, ubuntu/linux-fips, ubuntu/linux-gcp-fips, and ubuntu/linux-realtime.

What access does an attacker need to exploit this issue?

The severity vector identifies network attack access, low attack complexity, no required privileges, and no user interaction. Exploitation involves PDU length or offset values that cause nvmet_tcp_build_pdu_iovec() to walk beyond the request scatter-gather entries.

What is the likely impact of exploitation?

Out-of-bounds scatter-gather access can result in bogus length or offset values being passed to _copy_to_iter(), leading to a general protection fault or KASAN-detected failure. The supplied severity vector rates confidentiality, integrity, and availability impact as high.
