{"id":"AZL-72499","summary":"CVE-2025-68239 affecting package kernel 6.6.126.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nbinfmt_misc: restore write access before closing files opened by open_exec()\n\nbm_register_write() opens an executable file using open_exec(), which\ninternally calls do_open_execat() and denies write access on the file to\navoid modification while it is being executed.\n\nHowever, when an error occurs, bm_register_write() closes the file using\nfilp_close() directly. This does not restore the write permission, which\nmay cause subsequent write operations on the same file to fail.\n\nFix this by calling exe_file_allow_write_access() before filp_close() to\nrestore the write permission properly.","modified":"2026-04-01T05:22:09.905216Z","published":"2025-12-16T15:15:53Z","upstream":["CVE-2025-68239"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-68239"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.126.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-72499.json"}}],"schema_version":"1.7.5"}
