{"apiVersion":"1.0","identifier":"CVE-2026-74510","description":"In the Linux kernel, the following vulnerability has been resolved: Bluetooth: mgmt: fix UAF in pair command cancellation The pairing completion and authentication failure callbacks look up the pending MGMT_OP_PAIR_DEVICE command by walking hdev->mgmt_pending. The lookup returned a command that was still linked on the shared pending list, without keeping mgmt_pending_lock held for the later dereference and removal. A concurrent MGMT_OP_CANCEL_PAIR_DEVICE request can remove and free the same pending command before the callback uses it. The reverse race is also possible when cancel_pair_device() gets a command from pending_find() and a callback removes it before the cancel path dereferences it. This can lead to a use-after-free and a second list_del(). Make the pairing lookup helpers transfer ownership of the pending command by removing it from hdev->mgmt_pending while holding mgmt_pending_lock. The callbacks and cancel path then complete the command and free it directly, so racing paths cannot find or free the same command again. Take a temporary hci_conn reference in cancel_pair_device() because the command completion drops the reference stored in the pending command.","publishedAt":"2026-08-15T13:17:56","lastModifiedAt":"2026-08-23T13:16:45","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-74510","cvssScore":7.8,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00139,"riskScore":0.79,"affectedProduct":"linux","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-74510","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-74510","en":"https://www.redsauce.net/en/cves/CVE-2026-74510","fr":"https://www.redsauce.net/fr/cves/CVE-2026-74510","pt":"https://www.redsauce.net/pt/cves/CVE-2026-74510","de":"https://www.redsauce.net/de/cves/CVE-2026-74510","sk":"https://www.redsauce.net/sk/cves/CVE-2026-74510","el":"https://www.redsauce.net/el/cves/CVE-2026-74510"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-74510"}}
