Each resume therefore replaces the boot-time pointers\nand leaks both old allocations. The function also uses GFP_KERNEL from a\nsyscore resume callback, where interrupts are disabled and the non-boot\nCPUs are offline.\n\nReturn early if both buffers are already allocated. Clear the pointers\nin free_ga_log() so a partial allocation failure cannot leave ga_log\ndangling.","cvss_v4":null,"cvss_v3":null,"cwes":[],"references":["https://git.kernel.org/stable/c/00a7dd64888d6dd72110b40e2824a088cf7b7386","https://git.kernel.org/stable/c/8b95269d7a43b737c2c0e2fa77bf00cc8a3a4434","https://git.kernel.org/stable/c/94458b80d3b203c1c9e2c98aa7319b7713e006c0","https://git.kernel.org/stable/c/b6be275d19cee01f8f1f08a2ff18337103d05d40","https://git.kernel.org/stable/c/ff85cdc2889e1c885eed218ee5bc0b59e0235b3f"],"products":[],"source":"nvd","synced_at":"2026-10-22T16:41:11.231219466+00:00"},"epss":{"cve":"CVE-2026-98003","score":0.00168,"percentile":0.0605,"date":"2026-10-25"},"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).
