This covers both the explicitly\nenabled case and the initial state set by devm_regulator_get_exclusive().","state":0,"publishedAt":"2026-09-24T15:52:18.567+00:00","modifiedAt":"2026-10-19T09:08:30.634+00:00","affected":[{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"unaffected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/phy/renesas/phy-rcar-gen3-usb2.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"24843404efe47eab1ee88d7475a0be0f2f6fd9db\",\n                            \"lessThan\": \"bf7fefbc26e292c08cfe7b6496b879109ef1475a\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"24843404efe47eab1ee88d7475a0be0f2f6fd9db\",\n                            \"lessThan\": \"935f6e837a83b86b073a7601f699dc2c00e01322\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"24843404efe47eab1ee88d7475a0be0f2f6fd9db\",\n                            \"lessThan\": \"49c9b71b45081e5e5eeb507a2d6edb80d332dc59\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        }\n                    ]\n                }"},{"ecosystem":"Vendor product","name":"Linux","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"product\": \"Linux\",\n                    \"vendor\": \"Linux\",\n                    \"defaultStatus\": \"affected\",\n                    \"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\",\n                    \"programFiles\": [\n                        \"drivers/phy/renesas/phy-rcar-gen3-usb2.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.11\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.11\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.52\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.6\",\n                            \"lessThanOrEqual\": \"7.2.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.3\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[],"references":["https://git.kernel.org/stable/c/bf7fefbc26e292c08cfe7b6496b879109ef1475a","https://git.kernel.org/stable/c/935f6e837a83b86b073a7601f699dc2c00e01322","https://git.kernel.org/stable/c/49c9b71b45081e5e5eeb507a2d6edb80d332dc59"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-93276","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-93276","identifiers":["CVE-2026-93276"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
