This may leak the kernel\nstack contents. Make gpio_desc_to_lineinfo() return int so that the\n-ENODEV returned on failure to acquire the guard can be propagated to\nthe callers.\n\nWhile not strictly necessary: move the memset() before trying to acquire\nthe SRCU read lock too for good measure.","state":0,"publishedAt":"2026-10-18T15:17:46.695+00:00","modifiedAt":"2026-10-19T09:21:10.272+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/gpio/gpiolib-cdev.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"d83cee3d2bb131c7fca7e19f1e33dc7530fd7083\",\n                            \"lessThan\": \"8460ee5216ab9a38263b01dca4b0a27e083f70f3\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"d83cee3d2bb131c7fca7e19f1e33dc7530fd7083\",\n                            \"lessThan\": \"cf3d043582e106a0e57002bec8a6de8929ba3e1c\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"d83cee3d2bb131c7fca7e19f1e33dc7530fd7083\",\n                            \"lessThan\": \"60a466f231905cd96ae6f0f3c44a710c97873dac\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"d83cee3d2bb131c7fca7e19f1e33dc7530fd7083\",\n                            \"lessThan\": \"1feb5d39b05afd902ed9fc902ec5b15be03a4bdb\",\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/gpio/gpiolib-cdev.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"6.9\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"6.9\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.12.112\",\n                            \"lessThanOrEqual\": \"6.12.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.18.55\",\n                            \"lessThanOrEqual\": \"6.18.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"7.2.9\",\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/8460ee5216ab9a38263b01dca4b0a27e083f70f3","https://git.kernel.org/stable/c/cf3d043582e106a0e57002bec8a6de8929ba3e1c","https://git.kernel.org/stable/c/60a466f231905cd96ae6f0f3c44a710c97873dac","https://git.kernel.org/stable/c/1feb5d39b05afd902ed9fc902ec5b15be03a4bdb"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-98528","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-98528","identifiers":["CVE-2026-98528"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
