With those fields left unset, garbage function pointers\nmay be stored and later invoked from typec_partner_link_device() when a USB\ndevice is linked to the port. Uninitialized pd_revision and usb_capability\nsimilarly leak stack data through partner sysfs.\n\nZero-initialize the descriptor so optional callbacks remain NULL and the\nremaining fields are zero.","categories":["Operating systems"],"product":"Linux","vendor":"Linux","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98760","source_modified_at":"2026-10-21T12:56:34.390Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"0a4c005bd1715d8b32a368ed5516a6ee7e603d18","lessThan":"a39d53f70e637ff3970046c32106a0e64fca62cd","status":"affected","versionType":"git"},{"version":"0a4c005bd1715d8b32a368ed5516a6ee7e603d18","lessThan":"4b6823ce0e548491cb9663303cba28e18d351096","status":"affected","versionType":"git"},{"version":"0a4c005bd1715d8b32a368ed5516a6ee7e603d18","lessThan":"282be6ae8be791762740107c79cecf5121f66063","status":"affected","versionType":"git"},{"version":"0a4c005bd1715d8b32a368ed5516a6ee7e603d18","lessThan":"dac0c073c6ad5f1bbb5e9fea9023fc1b4dab5e14","status":"affected","versionType":"git"},{"version":"0a4c005bd1715d8b32a368ed5516a6ee7e603d18","lessThan":"c4b27b3605788bbf9e4251f3cd4ab94645ab036f","status":"affected","versionType":"git"}],"defaultStatus":"unaffected"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98760","source_modified_at":"2026-10-21T12:56:34.390Z","fetched_at":"2026-10-23T18:45:31.882637Z","product":"Linux","vendor":"Linux","versions":[{"version":"4.15","status":"affected"},{"version":"0","lessThan":"4.15","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-2026-98760","source_modified_at":"2026-10-21T12:56:34.390Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"4b6823ce0e548491cb9663303cba28e18d351096","basis":"first unaffected version stated in the CVE record"},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-98760","source_modified_at":"2026-10-21T12:56:34.390Z","fetched_at":"2026-10-23T18:45:31.882637Z","package":{"name":"Linux","ecosystem":null},"version":"282be6ae8be791762740107c79cecf5121f66063","basis":"first unaffected version stated in the CVE record"}],"cvss":null,"severity":null,"kev":{"listed":false},"epss":{"probability":0.00168,"percentile":0.0573,"score_date":"2026-10-23"},"published_at":"2026-10-18T15:47:50.759Z","modified_at":"2026-10-21T12:56:34.390Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-98760","fetched_at":"2026-10-23T18:45:31.882637Z","source_modified_at":"2026-10-21T12:56:34.390Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-98760","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/a39d53f70e637ff3970046c32106a0e64fca62cd"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/4b6823ce0e548491cb9663303cba28e18d351096"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/282be6ae8be791762740107c79cecf5121f66063"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/dac0c073c6ad5f1bbb5e9fea9023fc1b4dab5e14"},{"source":"CVE List","url":"https://git.kernel.org/stable/c/c4b27b3605788bbf9e4251f3cd4ab94645ab036f"}],"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":"2026-10-21T12:56:34.390Z","content_hash":"4eb2a34b986ebdeefd7236c2c7a78ceb0e2103241657d84d5e06ca4fa7e1cdd2"}}
