{"id":"DEBIAN-CVE-2023-52559","details":"In the Linux kernel, the following vulnerability has been resolved:  iommu/vt-d: Avoid memory allocation in iommu_suspend()  The iommu_suspend() syscore suspend callback is invoked with IRQ disabled. Allocating memory with the GFP_KERNEL flag may re-enable IRQs during the suspend callback, which can cause intermittent suspend/hibernation problems with the following kernel traces:  Calling iommu_suspend+0x0/0x1d0 ------------[ cut here ]------------ WARNING: CPU: 0 PID: 15 at kernel/time/timekeeping.c:868 ktime_get+0x9b/0xb0 ...
