Attackers can establish an A2DP source connection with an LC3plus session negotiated against a victim running bluealsad as an A2DP sink and transmit a non-fragmented LC3plus media header with a zero frame count to trigger a SIGFPE in the decoding thread, causing a denial of service on builds compiled with LC3plus support enabled.","state":0,"publishedAt":"2026-10-01T02:28:18.194+00:00","modifiedAt":"2026-10-01T19:04:17.577+00:00","affected":[{"ecosystem":"Vendor product","name":"bluez-alsa","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"defaultStatus\": \"unaffected\",\n                    \"vendor\": \"arkq\",\n                    \"product\": \"bluez-alsa\",\n                    \"packageURL\": \"pkg:github/arkq/bluez-alsa\",\n                    \"repo\": \"https://github.com/arkq/bluez-alsa\",\n                    \"versions\": [\n                        {\n                            \"status\": \"affected\",\n                            \"version\": \"0\",\n                            \"versionType\": \"git\",\n                            \"lessThan\": \"1a84465dd860d1be9dcf62339c6273e9e0632dd2\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N","score":2.1,"severity":"LOW"},{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N","score":3.5,"severity":"LOW"}],"references":["https://github.com/arkq/bluez-alsa/commit/1a84465dd860d1be9dcf62339c6273e9e0632dd2","https://www.vulncheck.com/advisories/bluealsa-bluealsad-lc3plus-decoder-division-by-zero-dos"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-101887","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-101887","identifiers":["CVE-2026-101887"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
