When it fails before the point of no return\n(fence allocation, config buffer allocation or batch submission), it\nreturns without touching stream->syncs.\n\nThe stream open path handles such failures in the caller, but\nxe_oa_config_locked() propagates the error without any cleanup, so the\nsyncs array and the fence references held by the parsed entries are\nleaked. The next config ioctl overwrites stream->syncs, making the\nmemory unreachable for good.\n\nClean up the parsed syncs when xe_oa_emit_oa_config() fails, matching\nthe cleanup done by the stream open error path.\n\n(cherry picked from commit 8af97b3da2cfce04e6b457c6eb17ed3c1daf912b)","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/027150e24e173a5dffe7f5ab3a6600618f634da2","https://git.kernel.org/stable/c/8d33c4987cd162527375a3905017ae129ba7c3fe","https://git.kernel.org/stable/c/948f346fe36e1d02353c3d61b1f6b66c6af91996","https://git.kernel.org/stable/c/fcf7943b0a38568c547d7b5702de1d8190480616"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:52:03.409947763+00:00"},"epss":{"cve":"CVE-2026-80903","score":0.00156,"percentile":0.04738,"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).
