But if that end I/O handler sets the PageError bit,\nand the submitter checks it, the bit could in some cases leak into the\nsubmission context for fast enough I/O.\n\nFix this by simply not checking PageError and just using the local\nret variable to check for submission errors.  This also fundamentally\nsolves the long problem documented in a comment in __extent_writepage\nby never leaking the error bit into the submission context.","state":0,"publishedAt":"2025-09-18T16:04:10.298+00:00","modifiedAt":"2026-10-03T10:54:54.024+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/btrfs/extent_io.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"61391d562229ed94899ed4b4973dc2f0c015292a\",\n                            \"lessThan\": \"3c26023365a955d2d69355f5167508a963e44333\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"61391d562229ed94899ed4b4973dc2f0c015292a\",\n                            \"lessThan\": \"d40be032ecd8ee1ca033bee43c7755d21fb4d72a\",\n                            \"status\": \"affected\",\n                            \"versionType\": \"git\"\n                        },\n                        {\n                            \"version\": \"61391d562229ed94899ed4b4973dc2f0c015292a\",\n                            \"lessThan\": \"3e92499e3b004baffb479d61e191b41b604ece9a\",\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/btrfs/extent_io.c\"\n                    ],\n                    \"versions\": [\n                        {\n                            \"version\": \"3.16\",\n                            \"status\": \"affected\"\n                        },\n                        {\n                            \"version\": \"0\",\n                            \"lessThan\": \"3.16\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.1.189\",\n                            \"lessThanOrEqual\": \"6.1.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.4.7\",\n                            \"lessThanOrEqual\": \"6.4.*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"semver\"\n                        },\n                        {\n                            \"version\": \"6.5\",\n                            \"lessThanOrEqual\": \"*\",\n                            \"status\": \"unaffected\",\n                            \"versionType\": \"original_commit_for_fix\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":7.8,"severity":"HIGH"}],"references":["https://git.kernel.org/stable/c/3c26023365a955d2d69355f5167508a963e44333","https://git.kernel.org/stable/c/d40be032ecd8ee1ca033bee43c7755d21fb4d72a","https://git.kernel.org/stable/c/3e92499e3b004baffb479d61e191b41b604ece9a"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2023-53429","license":"CVE Program Terms of Use","key":"cve-program:CVE-2023-53429","identifiers":["CVE-2023-53429"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
