{"id":"CVE-2024-45828","summary":"i3c: mipi-i3c-hci: Mask ring interrupts before ring stop request","details":"In the Linux kernel, the following vulnerability has been resolved:\n\ni3c: mipi-i3c-hci: Mask ring interrupts before ring stop request\n\nBus cleanup path in DMA mode may trigger a RING_OP_STAT interrupt when\nthe ring is being stopped. 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":"2026-04-02T12:19:09.208744Z","published":"2025-01-11T12:25:11.560Z","related":["MGASA-2025-0030","MGASA-2025-0032","SUSE-SU-2025:0289-1","SUSE-SU-2025:0428-1","SUSE-SU-2025:0499-1","SUSE-SU-2025:0557-1","SUSE-SU-2025:20165-1","SUSE-SU-2025:20166-1","SUSE-SU-2025:20248-1","SUSE-SU-2025:20249-1","USN-7379-2","USN-7380-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/45xxx/CVE-2024-45828.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/19cc5767334bfe980f52421627d0826c0da86721"},{"type":"WEB","url":"https://git.kernel.org/stable/c/6ca2738174e4ee44edb2ab2d86ce74f015a0cc32"},{"type":"WEB","url":"https://git.kernel.org/stable/c/9d745a56aea45e47f4755bc12e6429d6314dbb54"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a6cddf68b3405b272b5a3cad9657be0b02b34bf4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/a6dc4b4fda2e147e557050eaae51ff15edeb680b"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/45xxx/CVE-2024-45828.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-45828"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"3a379bbcea0af6280e1ca0d1edfcf4e68cde6ee0"},{"fixed":"a6cddf68b3405b272b5a3cad9657be0b02b34bf4"},{"fixed":"9d745a56aea45e47f4755bc12e6429d6314dbb54"},{"fixed":"a6dc4b4fda2e147e557050eaae51ff15edeb680b"},{"fixed":"19cc5767334bfe980f52421627d0826c0da86721"},{"fixed":"6ca2738174e4ee44edb2ab2d86ce74f015a0cc32"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-45828.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"}]}
