Description OSIDB Bzimport 2025-12-09 01:01:56 UTC 
In the Linux kernel, the following vulnerability has been resolved:

iommu/sprd: Release dma buffer to avoid memory leak

When attaching to a domain, the driver would alloc a DMA buffer which
is used to store address mapping table, and it need to be released
when the IOMMU domain is freed.
