However,\nxive_smp_probe() previously ignored this failure and proceeded to\ncall xive_setup_cpu_ipi(), which dereferences the already-freed\nxive_ipis pointer -- a use-after-free.\n\nNow that xive_smp_probe() returns int (previous patch), propagate\nthe error from xive_init_ipis() and xive_setup_cpu_ipi() through\nxive_smp_probe().  Check the return value in both pnv_smp_probe()\nand pSeries_smp_probe() so that IPI setup is aborted cleanly on\nfailure, avoiding the use-after-free.","score":7.4,"severity":"high","published":"2026-09-24T15:51:46.703Z","modified":"2026-10-30T12:36:35.383Z","withdrawn":false,"knownExploited":false,"affected":[],"products":[{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"243e25112d06b348f087a6f7aba4bbc288285bdd","status":"affected","lessThan":"89e1caa5b0aafe23e9938d9a311e9d41baee583e","versionType":"git"},{"version":"243e25112d06b348f087a6f7aba4bbc288285bdd","status":"affected","lessThan":"e36b1c2eafcaaddefa70d55e6fda74cf6cda38af","versionType":"git"},{"version":"243e25112d06b348f087a6f7aba4bbc288285bdd","status":"affected","lessThan":"2ea6238343691309e68308131c7e80c3ae05afea","versionType":"git"},{"version":"243e25112d06b348f087a6f7aba4bbc288285bdd","status":"affected","lessThan":"5c9ab0c9cede9f149733d330e2d7d45341b71359","versionType":"git"},{"version":"243e25112d06b348f087a6f7aba4bbc288285bdd","status":"affected","lessThan":"c554a8d376d5aea1b237ed6bef6f9fbfc550e67f","versionType":"git"},{"version":"243e25112d06b348f087a6f7aba4bbc288285bdd","status":"affected","lessThan":"411a3c016e7a95f5fa105a0587e07d0647a77727","versionType":"git"}],"defaultStatus":"unaffected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-93260"},{"vendor":"Linux","name":"Linux","platforms":[],"versions":[{"version":"4.12","status":"affected"},{"version":"0","status":"unaffected","lessThan":"4.12","versionType":"semver"},{"version":"6.1.191","status":"unaffected","lessThanOrEqual":"6.1.*","versionType":"semver"},{"version":"6.6.160","status":"unaffected","lessThanOrEqual":"6.6.*","versionType":"semver"},{"version":"6.12.114","status":"unaffected","lessThanOrEqual":"6.12.*","versionType":"semver"},{"version":"6.18.57","status":"unaffected","lessThanOrEqual":"6.18.*","versionType":"semver"},{"version":"7.2.6","status":"unaffected","lessThanOrEqual":"7.2.*","versionType":"semver"},{"version":"7.3","status":"unaffected","lessThanOrEqual":"*","versionType":"original_commit_for_fix"}],"defaultStatus":"affected","cpes":[],"source":"Linux","url":"https://www.cve.org/CVERecord?id=CVE-2026-93260"}],"remediation":[],"references":["https://git.kernel.org/stable/c/89e1caa5b0aafe23e9938d9a311e9d41baee583e","https://git.kernel.org/stable/c/e36b1c2eafcaaddefa70d55e6fda74cf6cda38af","https://git.kernel.org/stable/c/2ea6238343691309e68308131c7e80c3ae05afea","https://git.kernel.org/stable/c/5c9ab0c9cede9f149733d330e2d7d45341b71359","https://git.kernel.org/stable/c/c554a8d376d5aea1b237ed6bef6f9fbfc550e67f","https://git.kernel.org/stable/c/411a3c016e7a95f5fa105a0587e07d0647a77727"],"sources":[{"name":"CVE","id":"CVE-2026-93260","modified":"2026-10-30T12:36:35.383Z","url":"https://www.cve.org/CVERecord?id=CVE-2026-93260"}],"assessments":[{"source":"Linux","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","score":7.4}],"sourceAffected":[],"observedAt":"2026-10-30T13:55:51.344Z","kev":{"status":"not-listed","checkedAt":"2026-11-15T02:25:31.038Z"},"coverage":[{"source":"NVD","status":"not-checked"},{"source":"GHSA","status":"not-checked"},{"source":"EUVD","status":"not-checked"},{"source":"EPSS","status":"not-checked"}],"evidence":[],"aiSummary":null}
