{"id":"AZL-49212","summary":"CVE-2024-45029 affecting package kernel for versions less than 6.6.51.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ni2c: tegra: Do not mark ACPI devices as irq safe\n\nOn ACPI machines, the tegra i2c module encounters an issue due to a\nmutex being called inside a spinlock. This leads to the following bug:\n\n\tBUG: sleeping function called from invalid context at kernel/locking/mutex.c:585\n\t...\n\n\tCall trace:\n\t__might_sleep\n\t__mutex_lock_common\n\tmutex_lock_nested\n\tacpi_subsys_runtime_resume\n\trpm_resume\n\ttegra_i2c_xfer\n\nThe problem arises because during __pm_runtime_resume(), the spinlock\n&dev-\u003epower.lock is acquired before rpm_resume() is called. Later,\nrpm_resume() invokes acpi_subsys_runtime_resume(), which relies on\nmutexes, triggering the error.\n\nTo address this issue, devices on ACPI are now marked as not IRQ-safe,\nconsidering the dependency of acpi_subsys_runtime_resume() on mutexes.","modified":"2026-04-01T05:17:20.064069Z","published":"2024-09-11T16:15:07Z","upstream":["CVE-2024-45029"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-45029"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.51.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-49212.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
