21 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: virtio-blk: don't keep queue frozen during system suspend Commit 4ce6e2db00de ("virtio-blk: Ensure no requests in virtqueues before deleting vqs.") replaces queue quiesce with queue freeze in virtio-blk's PM callbacks. And the motivation is to drain inflight IOs before suspending. block layer's queue freeze looks very handy, but it is also easy to cause deadlock, such as, any attempt to call into bio_queue_enter() may run into deadlock if t... • https://git.kernel.org/stable/c/d738f3215bb4f88911ff4579780a44960c8e0ca5 •

21 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: dm thin: make get_first_thin use rcu-safe list first function The documentation in rculist.h explains the absence of list_empty_rcu() and cautions programmers against relying on a list_empty() -> list_first() sequence in RCU safe code. This is because each of these functions performs its own READ_ONCE() of the list head. This can lead to a situation where the list_empty() sees a valid list entry, but the subsequent list_first() sees a diffe... • https://git.kernel.org/stable/c/b10ebd34cccae1b431caf1be54919aede2be7cbe •

21 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: net: stmmac: dwmac-tegra: Read iommu stream id from device tree Nvidia's Tegra MGBE controllers require the IOMMU "Stream ID" (SID) to be written to the MGBE_WRAP_AXI_ASID0_CTRL register. The current driver is hard coded to use MGBE0's SID for all controllers. This causes softirq time outs and kernel panics when using controllers other than MGBE0.

This prevents subsequent probe attempts from succeeding, even if the issue is corrected, unless the device is released. Additionally, cleanup is also needed in the less likely case of platform_device_register_full() failure.
