{"id":"AZL-104262","summary":"CVE-2026-97904 affecting package kernel 6.6.157.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ncpufreq: initialize policy rwsem before sysfs publication\n\ncpufreq_policy_alloc() initializes policy-\u003erwsem after\nkobject_init_and_add() has created the policy sysfs directory and its\ndefault attributes. A sysfs access can therefore reach a policy callback\nbefore the semaphore has been initialized.\n\nInitialize policy-\u003erwsem before publishing the policy kobject so sysfs\ncallbacks always see an initialized semaphore.","modified":"2026-09-26T14:16:11.131774015Z","published":"2026-09-25T11:17:17Z","upstream":["CVE-2026-97904"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-97904"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.157.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-104262.json"}}],"schema_version":"1.9.0"}
