| Vector | AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 6.15.0-rc2-next-20250417-00001-gf6a27738686c-dirty
Description
The issue is related to spinlock recursion in the mtk-star-emac driver, which can occur when enabling DMA interrupts again in rx/tx poll. This can lead to a spinlock recursion error. The problem is resolved by using spin lock irqsave and spin unlock irqrestore instead of spin lock and spin unlock.
Recommendations
For Linux kernel versions prior to 6.15.0-rc2-next-20250417-00001-gf6a27738686c-dirty, update to a newer version that includes the fix for spinlock recursion issues in the mtk-star-emac driver. As a temporary workaround, consider disabling the
mtk star handle irq function until a patch is available. Restrict access to the mtk star emac driver to minimize the risk of exploitation. Avoid using the mtk star rx poll function in the affected API endpoint until the issue is resolved.Exploit
