{"schema":"threatline.record/2","record":{"id":"CVE-2026-98665","aliases":[],"summary":"iio: health: max30102: fix NULL dereference in interrupt handler","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: health: max30102: fix NULL dereference in interrupt handler\n\nThe interrupt is requested in max30102_probe() and stays enabled\nfor the lifetime of the device, but indio_dev->active_scan_mask is only\nvalid while a buffer is enabled. When an interrupt arrives while no\nbuffer is enabled, the handler dereferences the NULL active_scan_mask:\n\n  Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000\n  Call trace:\n   __bitmap_weight+0x64/0x98 (P)\n   max30102_interrupt_handler+0x48/0x160 [max30102]\n\nCall max30102_fifo_count() at the top of the handler and return early\nunless it reports a FIFO sample is ready. Because FIFO_RDY is the only\ninterrupt source enabled in max30102_chip_init(), an invocation of\nmax30102_interrupt_handler() without the FIFO_RDY interrupt status bit\nset carries no data to read and can return before touching\nactive_scan_mask. A negative return from max30102_fifo_count()\nindicates a failed interrupt status read and is treated the same way.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98665","source_modified_at":"2026-10-21T12:55:30.413Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"90579b69e94bf11ea0745ff003e82a6ce9725f96","lessThan":"2a74f30a7bb305cdc5c3e3e9239b32bb84f3529f","status":"affected","versionType":"git"},{"version":"90579b69e94bf11ea0745ff003e82a6ce9725f96","lessThan":"eeb23ba97bd8016e815ef70300b8d34a0a316b90","status":"affected","versionType":"git"},{"version":"90579b69e94bf11ea0745ff003e82a6ce9725f96","lessThan":"60699102827fdb51f9591414165359c8e867f302","status":"affected","versionType":"git"},{"version":"90579b69e94bf11ea0745ff003e82a6ce9725f96","lessThan":"8d6f98972fe2bd6f73f39d982af0c85d766a1503","status":"affected","versionType":"git"},{"version":"90579b69e94bf11ea0745ff003e82a6ce9725f96","lessThan":"f0ea4824deebf21dacfbe397c4b0a5fd3e745a8d","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98665","source_modified_at":"2026-10-21T12:55:30.413Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"4.16","status":"affected"},{"version":"0","lessThan":"4.16","status":"unaffected","versionType":"semver"},{"version":"6.6.160","lessThanOrEqual":"6.6.*","status":"unaffected","versionType":"semver"},{"version":"6.12.113","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.56","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.10","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}],"defaultStatus":"affected"}],"fixed_versions":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98665","source_modified_at":"2026-10-21T12:55:30.413Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"2a74f30a7bb305cdc5c3e3e9239b32bb84f3529f","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98665","source_modified_at":"2026-10-21T12:55:30.413Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"60699102827fdb51f9591414165359c8e867f302","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98665","source_modified_at":"2026-10-21T12:55:30.413Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"8d6f98972fe2bd6f73f39d982af0c85d766a1503","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.05712,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:44:35.323Z","modified_at":"2026-10-21T12:55:30.413Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98665","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:55:30.413Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98665","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://git.kernel.org/stable/c/2a74f30a7bb305cdc5c3e3e9239b32bb84f3529f"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/eeb23ba97bd8016e815ef70300b8d34a0a316b90"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/60699102827fdb51f9591414165359c8e867f302"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/8d6f98972fe2bd6f73f39d982af0c85d766a1503"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/f0ea4824deebf21dacfbe397c4b0a5fd3e745a8d"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":"product","confidence":"heuristic","reviewed":false},"change_timestamp":"2026-10-21T12:55:30.413Z","content_hash":"2363b545fb97773de262884c64299e089e6e27c11117d4d6be13aafaa63202a6"}}
