The read call can create an order-0 folio to\nread the first 4096 bytes from the disk. But then udev is preempted.\nNext, someone tries to mount an 8k-sectorsize filesystem from the same\nblock device. The filesystem calls set_blksize, which sets i_blksize to\n8192 and the minimum folio order to 1.\nNow udev resumes, still holding the order-0 folio it allocated. It then\ntries to schedule a read bio and do_mpage_readahead tries to create\nbufferheads for the folio. Unfortunately, blocks_per_folio == 0 because\nthe page size is 4096 but the blocksize is 8192 so no bufferheads are\nattached and the bh walk never sets bdev. We then submit the bio with a\nNULL block device and crash.\nTherefore, truncate the page cache after flushing but before updating\ni_blksize. However, that's not enough -- we also need to lock out file\nIO and page faults during the update. Take both the i_rwsem and the\ninvalidate_lock in exclusive mode for invalidations, and in shared mode\nfor read/write operations.\nI don't know if this is the correct fix, but xfs/259 found it."], "name": "CVE-2025-38073", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:10", "fix_state": "Affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 10"}, {"cpe": "cpe:/o:redhat:enterprise_linux:6", "fix_state": "Not affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 6"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Under investigation", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Under investigation", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Affected", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 8"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Affected", "package_name": "kernel", "product_name": "Red Hat Enterprise Linux 9"}, {"cpe": "cpe:/o:redhat:enterprise_linux:9", "fix_state": "Affected", "package_name": "kernel-rt", "product_name": "Red Hat Enterprise Linux 9"}], "public_date": "2025-06-18T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2025-38073\nhttps://nvd.nist.gov/vuln/detail/CVE-2025-38073\nhttps://lore.kernel.org/linux-cve-announce/2025061839-CVE-2025-38073-4f76@gregkh/T"], "threat_severity": "Moderate"}
