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 •

The legacy users of exportfs_encode_fh(), namely, nfsd and name_to_handle_at(2) syscall are ready to cope with the possibility of failure to encode a file handle.

19 Jan 2025 — In the Linux kernel, the following vulnerability has been resolved: usb: gadget: u_serial: Disable ep before setting port to null to fix the crash caused by port being null Considering that in some extreme cases, when performing the unbinding operation, gserial_disconnect has cleared gser->ioport, which triggers gadget reconfiguration, and then calls gs_read_complete, resulting in access to a null pointer. Therefore, ep is disabled before gserial_disconnect sets port to null to prevent this from happening. ... • https://git.kernel.org/stable/c/c1dca562be8ada614ef193aa246c6f8705bcd6b9 •
