{"apiVersion":"1.0","identifier":"CVE-2026-72489","description":"In the Linux kernel, the following vulnerability has been resolved: staging: nvec: fix use-after-free in nvec_rx_completed() In nvec_rx_completed(), when an incomplete RX transfer is detected, nvec_msg_free() is called to return the message back to the pool by clearing its -used- atomic flag. Immediately after this, the code accesses nvec->rx->data[0] to check the message type. Since nvec_msg_free() marks the pool slot as available via atomic_set(), any concurrent or subsequent call to nvec_msg_alloc() could claim that same slot and overwrite its data[] array. Reading nvec->rx->data[0] after freeing the message is therefore a use-after-free. Fix this by saving the message type byte before calling nvec_msg_free(), then using the saved value for the battery quirk check.","publishedAt":"2026-08-15T06:22:23","lastModifiedAt":"2026-08-17T06:19:17","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-72489","cvssScore":8.4,"cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","epssProbability":0.00148,"riskScore":0.85,"affectedProduct":"Linux kernel","affectedVersions":"unknown","vulnerabilityType":"Kernel","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-72489","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-72489","en":"https://www.redsauce.net/en/cves/CVE-2026-72489","fr":"https://www.redsauce.net/fr/cves/CVE-2026-72489","pt":"https://www.redsauce.net/pt/cves/CVE-2026-72489","de":"https://www.redsauce.net/de/cves/CVE-2026-72489","sk":"https://www.redsauce.net/sk/cves/CVE-2026-72489","el":"https://www.redsauce.net/el/cves/CVE-2026-72489"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-72489"}}
