AI-suggested
A patch is available that adds a spinlock to protect the DONE_INT_MASK and ABORT_INT_MASK registers, preventing race conditions. Users should apply the official Linux kernel updates that include this fix. The vendor advisory from Ubuntu confirms the availability of this fix. No additional mitigation is required beyond applying the patch.
Description
A race condition vulnerability in the Linux kernel's dmaengine dw-edma driver was fixed by adding a spinlock to protect shared DONE_INT_MASK and ABORT_INT_MASK registers. These registers are shared by all DMA channels and require atomic read-modify-write operations, which were previously unprotected, allowing concurrent access and race conditions. The vulnerability affects specific Linux kernel versions and has a CVSS score of 8.8. A patch is available to address this issue.
