21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu: Don't unregister on shutdown Michael Walle says he noticed the following stack trace while performing a shutdown with "reboot -f". He suggests he got "lucky" and just hit the correct spot for the reboot while there was a packet transmission in flight.

21 Aug 2024 — In the Linux kernel, the following vulnerability has been resolved: iommu/arm-smmu-v3: Don't unregister on shutdown Similar to SMMUv2, this driver calls iommu_device_unregister() from the shutdown path, which removes the IOMMU groups with no coordination whatsoever with their users - shutdown methods are optional in device drivers. This can lead to NULL pointer dereferences in those drivers' DMA API calls, or worse. Instead of calling the full arm_smmu_device_remove() from arm_smmu_device_shutdown(), let's ... • https://git.kernel.org/stable/c/57365a04c92126525a58bf7a1599ddfa832415e9 •
