Use memcpy_from_page(), memcpy_to_page(), and\nmemzero_page() for the other page accesses. Remove unnecessary local\nmappings from ntfs_write_cb(), where pages are accessed through the vmap()\nmapping.","state":0,"publishedAt":"2026-09-17T16:06:33.888+00:00","modifiedAt":"2026-10-19T08:58:32.441+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                        \"fs/ntfs/compress.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"495e90fa334828d4119061e2726af51d0a0fb4ed\",\n                            \"lessThan\": \"950e2ecc7aec21af24b05bc661a097a81c670409\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"495e90fa334828d4119061e2726af51d0a0fb4ed\",\n                            \"lessThan\": \"6e03fbd5f772ad24ea64f7632e4d0d73184787ca\",\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                        \"fs/ntfs/compress.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"7.1\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"7.1\",\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/950e2ecc7aec21af24b05bc661a097a81c670409","https://git.kernel.org/stable/c/6e03fbd5f772ad24ea64f7632e4d0d73184787ca"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-90134","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-90134","identifiers":["CVE-2026-90134"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
