Depending on timing between ring stop request\ncompletion, interrupt handler removal and code execution this may lead\nto a NULL pointer dereference in hci_dma_irq_handler() if it gets to run\nafter the io_data pointer is set to NULL in hci_dma_cleanup().\n\nPrevent this my masking the ring interrupts before ring stop request.","modified":"2026-04-01T05:18:48.219156Z","published":"2025-01-11T13:15:21Z","upstream":["CVE-2024-45828"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-45828"}],"affected":[{"package":{"name":"kernel","ecosystem":"Azure Linux:3","purl":"pkg:rpm/azure-linux/kernel"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.6.76.1-1"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-56131.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"}]}
