{"id":"AZL-102702","summary":"CVE-2026-90249 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\niio: light: gp2ap002: Fix unbalanced runtime PM on repeated event writes\n\nThe IIO core does not filter duplicate writes to the event enable\nattribute, so writing the same value twice invokes\nwrite_event_config() twice. Enabling twice leaks a runtime PM\nreference, preventing the device from ever suspending again;\ndisabling twice underflows the usage count and triggers a\n\"Runtime PM usage count underflow\" warning.\n\nBail out early when the requested state matches the current state.\nWhile at it, switch to pm_runtime_resume_and_get() so a failed\nresume is propagated to userspace instead of silently marking the\nevent enabled.","modified":"2026-09-18T14:15:34.637062333Z","published":"2026-09-17T17:17:21Z","upstream":["CVE-2026-90249"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90249"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"6.6.150.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-102702.json"}}],"schema_version":"1.9.0"}
