As a result, the embedded struct device does not have a DMA mask initialized by default. After recent DMA API hardening changes, dma_map_sg() and related helpers now require a valid dma_mask to be present, otherwise the driver may crash or trigger warnings when attempting DMA mapping operations. Fix this by explicitly initializing the DMA mask for the SSI controller device and setting a 32-bit DMA mask, which matches the hardware capabilities. The Linux kernel CVE team has assigned CVE-2026-89594 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/hsi/controllers/omap_ssi_core.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/e8d47e309c704df95816e7442f05947424d8b33f https://git.kernel.org/stable/c/4e019e5e247bfe877fdf288f2d6ec1b4c850c7c6 https://git.kernel.org/stable/c/fbffbfdae55954213fea99c5c9856c48dc705019 https://git.kernel.org/stable/c/e81250ec6b69248b00d38c523dc6a13efaf38aab
