If an interrupt arrives while the create\npath holds the plain xa_lock, the lookup spins forever trying to\nacquire the same lock.\n\nUse IRQ-safe XArray helpers for all QP and CQ create-path updates,\nincluding the GSI QP store and error paths. Initialize both arrays with\nXA_FLAGS_LOCK_IRQ so sleeping allocations preserve interrupt state.","score":null,"severity":"unknown","published":"2026-10-06T08:46:40.955Z","modified":"2026-10-30T12:38:02.585Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"1fc9c1933959d2776a1ce7bf424251b8b5b586cd","status":"affected","lessThan":"e32aa1d85126e6d5ef6efd594ced3f75178886ce","versionType":"git"},{"version":"4545f355654d044d35a31cd01cc46f491a8a7c36","status":"affected","lessThan":"74d4085221a7ec5440996af199ccadfa75b9eb0e","versionType":"git"},{"version":"98df2aee1459ee1c62c70cbe9b370d2a532aea36","status":"affected","lessThan":"00baeade709fb66da647e8327e8398bb532e30f7","versionType":"git"},{"version":"610ef81797bb4f709e8675c1d8d093bb9ccdcbd8","status":"affected","versionType":"git"},{"version":"c0a83f29a24c7e7f8516630848ef6db4c174deed","status":"affected","versionType":"git"},{"version":"05b8ca493dd02319bca93c640b259c2ba51ef321","status":"affected","versionType":"git"},{"version":"92101d7bd67cf313d65baede27118614a283f6bf","status":"affected","versionType":"git"},{"version":"233f1b7fe2980e4e238fe03dd3ceddfd082cb4c8","status":"affected","versionType":"git"},{"version":"6e32f84b63c054e09392153125d7202abab2d14b","status":"affected","versionType":"git"},{"version":"ec987c0654651036dad6a42f7fa2a6d7c16a3687","status":"affected","versionType":"git"},{"version":"c92686867638cda954fdb2bdbac8a75e3aa6eaae","status":"affected","versionType":"git"},{"version":"6.1.188","status":"affected","lessThan":"6.2","versionType":"semver"},{"version":"6.6.157","status":"affected","lessThan":"6.7","versionType":"semver"},{"version":"6.12.110","status":"affected","lessThan":"6.13","versionType":"semver"},{"version":"6.1.191","status":"affected","lessThan":"6.2","versionType":"semver"},{"version":"6.6.160","status":"affected","lessThan":"6.7","versionType":"semver"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98353"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"6.18.52","status":"affected","lessThan":"6.18.58","versionType":"semver"},{"version":"7.2.6","status":"affected","lessThan":"7.2.8","versionType":"semver"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-98353"}],"remediation":[],"references":["https://git.kernel.org/stable/c/e32aa1d85126e6d5ef6efd594ced3f75178886ce","https://git.kernel.org/stable/c/74d4085221a7ec5440996af199ccadfa75b9eb0e","https://git.kernel.org/stable/c/00baeade709fb66da647e8327e8398bb532e30f7"],"sources":[{"name":"CVE","id":"CVE-2026-98353","modified":"2026-10-30T12:38:02.585Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-98353"}],"assessments":[],"sourceAffected":[],"observedAt":"2026-10-30T14:01:12.710Z","kev":{"status":"not-listed","checkedAt":"2026-11-14T21:40:35.012Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
