10 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: kTLS, Fix crash in RX resync flow For the TLS RX resync flow, we maintain a list of TLS contexts that require some attention, to communicate their resync information to the HW. Here we fix list corruptions, by protecting the entries against movements coming from resync_handle_seq_match(), until their resync handling in napi is fully completed. • https://git.kernel.org/stable/c/e9ce991bce5bacf71641bd0f72f4b7c589529f40 •

10 Apr 2024 — In the Linux kernel, the following vulnerability has been resolved: clk: sunxi-ng: Unregister clocks/resets when unbinding Currently, unbinding a CCU driver unmaps the device's MMIO region, while leaving its clocks/resets and their providers registered. This can cause a page fault later when some clock operation tries to perform MMIO. Fix this by separating the CCU initialization from the memory allocation, and then using a devres callback to unregister the clocks and resets.
