{"id":"AZL-100808","summary":"CVE-2026-89594 affecting package kernel 6.6.150.1-1","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nhsi: omap_ssi_core: fix missing DMA mask setup for SSI controller device\n\nThe OMAP SSI driver uses a synthetic HSI controller device allocated via\nhsi_alloc_controller(), which does not go through the normal OF/platform\ndevice initialization path.\n\nAs a result, the embedded struct device does not have a DMA mask\ninitialized by default.\n\nAfter recent DMA API hardening changes, dma_map_sg() and related helpers\nnow require a valid dma_mask to be present, otherwise the driver may\ncrash or trigger warnings when attempting DMA mapping operations.\n\nFix this by explicitly initializing the DMA mask for the SSI controller\ndevice and setting a 32-bit DMA mask, which matches the hardware\ncapabilities.","modified":"2026-09-13T06:06:36Z","published":"2026-09-11T20:19:44Z","upstream":["CVE-2026-89594"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-89594"}],"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-100808.json"}}],"schema_version":"1.9.0"}
