This prevents the filesystem from entering an\ninconsistent state where the inline data flag is set but the file size\nexceeds what can be stored inline.\n\nWithout this fix, the following sequence causes a kernel BUG_ON():\n\n1. Mount filesystem with inode that has inline flag set and small size\n2. truncate(file, 50MB) - grows size but inline flag remains set\n3. sendfile() attempts to write data\n4. ext4_write_inline_data() hits BUG_ON(write_size > inline_capacity)\n\nThe crash occurs because ext4_write_inline_data() expects inline storage\nto accommodate the write, but the actual inline capacity (~60 bytes for\ni_block + ~96 bytes for xattrs) is far smaller than the file size and\nwrite request.\n\nThe fix checks if the new size from setattr exceeds the inode's actual\ninline capacity (EXT4_I(inode)->i_inline_size) and converts the file to\nextent-based storage before proceeding with the size change.\n\nThis addresses the root cause by ensuring the inline data flag and file\nsize remain consistent during truncate operations."}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles":

A local user could exploit a vulnerability where the `truncate()` function, when used to expand a file beyond its inline data capacity, fails to properly convert the file to extent-based storage. This inconsistency can lead to a kernel crash (BUG_ON) if a subsequent write operation, such as `sendfile()`, attempts to write data to the oversized inline file. This issue results in a denial of service."], "name": "CVE-2026-31452", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:10", "fix_state": "Fix deferred", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 10"}, {"cpe": "cpe:/o:redhat:enterprise_linux:6", "fix_state": "Out of support scope", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 6"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Fix deferred", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Fix deferred", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Fix deferred", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Fix deferred", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Fix deferred", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Fix deferred", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 9"}], "public_date": "2026-04-22T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2026-31452\nhttps://nvd.nist.gov/vuln/detail/CVE-2026-31452\nhttps://lore.kernel.org/linux-cve-announce/2026042248-CVE-2026-31452-9f5b@gregkh/T"], "threat_severity": "Moderate"}
