{"schema":"threatline.record/2","record":{"id":"CVE-2026-98795","aliases":[],"summary":"net: sparx5: skip ptp deinit if init was skipped","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nnet: sparx5: skip ptp deinit if init was skipped\n\nsparx5_ptp_init() returns early on the base lan969x variants\nbecause they do not have the SPX5_FEATURE_PTP flag. It also returns early\nwhen no \"ptp\" interrupt is described. Unbinding the driver then causes a\nNULL pointer dereference when cleaning up uninitialized tx_skbs queues:\n\n    Unable to handle kernel NULL pointer dereference at virtual address\n    0000000000000008\n    Call trace:\n    skb_queue_purge_reason+0x68/0x120 (P)\n    sparx5_ptp_deinit+0x64/0xc0\n    mchp_sparx5_remove+0x38/0x70\n    platform_remove+0x20/0x30\n    device_remove+0x4c/0x80\n\nBefore per-port tx_skbs were added, a NULL dereference would have happened\nwhen calling ptp_clock_unregister() on the never-registered PTP clocks.\n\nFix by returning early in sparx5_ptp_deinit() if PTP is not used.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98795","source_modified_at":"2026-10-19T09:25:48.008Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"0933bd04047c3b96ba49545a8f91e7e6f8f666ff","lessThan":"35c706d6eb1963735814c5f5bb2674a96eacf3cc","status":"affected","versionType":"git"},{"version":"0933bd04047c3b96ba49545a8f91e7e6f8f666ff","lessThan":"2879b65bfa548e10d59c5fba91d17f8a00cd7029","status":"affected","versionType":"git"},{"version":"0933bd04047c3b96ba49545a8f91e7e6f8f666ff","lessThan":"0d2c49915bc3aea4521cda5e4d42f24f63b94585","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98795","source_modified_at":"2026-10-19T09:25:48.008Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"5.18","status":"affected"},{"version":"0","lessThan":"5.18","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-2026-98795","source_modified_at":"2026-10-19T09:25:48.008Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"35c706d6eb1963735814c5f5bb2674a96eacf3cc","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98795","source_modified_at":"2026-10-19T09:25:48.008Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"2879b65bfa548e10d59c5fba91d17f8a00cd7029","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98795","source_modified_at":"2026-10-19T09:25:48.008Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"0d2c49915bc3aea4521cda5e4d42f24f63b94585","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00166,"percentile":0.05517,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:48:39.633Z","modified_at":"2026-10-19T09:25:48.008Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98795","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-19T09:25:48.008Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98795","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/35c706d6eb1963735814c5f5bb2674a96eacf3cc"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/2879b65bfa548e10d59c5fba91d17f8a00cd7029"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/0d2c49915bc3aea4521cda5e4d42f24f63b94585"}],"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":"2026-10-19T09:25:48.008Z","content_hash":"ed10e4d7c5c22a7a56094208bf7a0afb9a9ab53e30b307f0b08e683b8c15bb26"}}
