{"id":"AZL-103020","summary":"CVE-2026-90208 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nclocksource/drivers/samsung_pwm: Switch to raw_spinlock_t type\n\nSamsung PWM timer might be used as a clock source on some legacy systems.\nWhen PREEMPT_RT is enabled on ARM, regular spinlock is converted to a\nsleeping lock (mutex-based), which must not be used in atomic context\nsuch as hard interrupt handlers. Switch the samsung_pwm_lock to the\nraw_spinlock, which remains a true non-sleeping spinlock even\nunder PREEMPT_RT.","modified":"2026-09-18T14:18:03.150084551Z","published":"2026-09-17T17:17:15Z","upstream":["CVE-2026-90208"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-90208"}],"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-103020.json"}}],"schema_version":"1.9.0"}
