High [CVE-2026-74528] hold conn in hci_past_sync callback
CVE-2026-74528Source published Source updated
In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_sync: hold conn in hci_past_sync() callback Avoids giving freed pointers to hci_conn_valid(), which kmalloc may have reused. Hold refcount to avoid that. This vulnerability, a use-after-free, occurs when the hci_sync component improperly handles connection references, leading to the potential reuse and access of freed memory pointers. A remote attacker could exploit this to cause system instability, resulting in a denial of service (DoS), or potentially achieve privilege escalation. Red Hat severity: Moderate — CVSS 7 (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H). Weakness: CWE-825. Affected Red Hat products: Red Hat Enterprise Linux 10.
