A fix is available — apply it.

The do_hidp_sock_ioctl function in net/bluetooth/hidp/sock.c in the Linux kernel before 5.0.15 allows a local user to obtain potentially sensitive information from kernel stack memory via a HIDPCONNADD command, because a name field may not end with a '\0' character.

A fix is available. Apply it within your standard update timelines at low or medium mission impact and sooner than that at high.

Exploitation none (no KEV listing, exploit record or EPSS ≥ 50%) · Automatable unknown (not published for this CVE) · Technical impact partial (CVSS below 9.0). Mission impact is CISA's Mission & Well-being decision point, and only you can judge it: high means the affected system is essential to your organisation's mission, or its compromise could cause irreversible harm to people.
