{"id":"AZL-88497","summary":"CVE-2026-46072 affecting package kernel for versions less than 6.6.141.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nntfs3: add buffer boundary checks to run_unpack()\n\nrun_unpack() checks `run_buf \u003c run_last` at the top of the while loop\nbut then reads size_size and offset_size bytes via run_unpack_s64()\nwithout verifying they fit within the remaining buffer.  A crafted NTFS\nimage with truncated run data in an MFT attribute triggers an OOB heap\nread of up to 15 bytes when the filesystem is mounted.\n\nAdd boundary checks before each run_unpack_s64() call to ensure the\ndeclared field size does not exceed the remaining buffer.\n\nFound by fuzzing with a source-patched harness (LibAFL + QEMU).","modified":"2026-08-28T17:48:05.278462765Z","published":"2026-05-27T14:17:28Z","upstream":["CVE-2026-46072"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46072"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.141.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-88497.json"}}],"schema_version":"1.9.0"}
