{"id":"AZL-93935","summary":"CVE-2026-64375 affecting package kernel for versions less than 6.6.145.2-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nproc: protect ptrace_may_access() with exec_update_lock (FD links)\n\nproc_pid_get_link() and proc_pid_readlink() currently look up the task from\nthe pid once, then do the ptrace access check on that task, then look up\nthe task from the pid a second time to do the actual access.\nThat's racy in several ways.\n\nTo fix it, pass the task to the -\u003eproc_get_link() handler, and instead of\nproc_fd_access_allowed(), introduce a new helper call_proc_get_link() that\nlooks up and locks the task, does the access check, and calls\n-\u003eproc_get_link().","modified":"2026-08-28T17:47:46.449324254Z","published":"2026-07-25T10:17:20Z","upstream":["CVE-2026-64375"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-64375"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.145.2-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-93935.json"}}],"schema_version":"1.9.0"}
