In other words, user mode may race and modify the packet header (e.g. header.count), causing checks (e.g. size checks) in kernel code to be invalid. This may lead to out-of-bounds read/write issues.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.0},"cwes":["CWE-367"],"references":["https://www.qualcomm.com/company/product-security/bulletins/august-2023-bulletin","https://www.qualcomm.com/company/product-security/bulletins/august-2023-bulletin"],"products":["qualcomm:fastconnect_6800_firmware","qualcomm:fastconnect_6900_firmware","qualcomm:fastconnect_7800_firmware","qualcomm:qca6391_firmware","qualcomm:qca6426_firmware","qualcomm:qca6436_firmware","qualcomm:qcn9074_firmware","qualcomm:qcs410_firmware","qualcomm:qcs610_firmware","qualcomm:sd865_5g_firmware","qualcomm:snapdragon_865\\+_5g_firmware","qualcomm:snapdragon_865_5g_firmware","qualcomm:snapdragon_870_5g_firmware","qualcomm:snapdragon_8_gen_1_firmware","qualcomm:snapdragon_x55_5g_firmware","qualcomm:snapdragon_xr2_5g_firmware","qualcomm:sw5100_firmware","qualcomm:sw5100p_firmware","qualcomm:sxr2130_firmware","qualcomm:wcd9341_firmware","qualcomm:wcd9370_firmware","qualcomm:wcd9380_firmware","qualcomm:wcn3660b_firmware","qualcomm:wcn3680b_firmware","qualcomm:wcn3950_firmware","qualcomm:wcn3980_firmware","qualcomm:wcn3988_firmware","qualcomm:wsa8810_firmware","qualcomm:wsa8815_firmware","qualcomm:wsa8830_firmware","qualcomm:wsa8835_firmware"],"source":"nvd","synced_at":"2026-10-19T21:38:35.729974749+00:00"},"epss":{"cve":"CVE-2023-28576","score":0.00085,"percentile":0.00283,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
