27 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: net: usb: rtl8150: enable basic endpoint checking Syzkaller reports [1] encountering a common issue of utilizing a wrong usb endpoint type during URB submitting stage. This, in turn, triggers a warning shown below. For now, enable simple endpoint checking (specifically, bulk and interrupt eps, testing control one is not essential) to mitigate the issue with a view to do other related cosmetic changes later, if they are necessary.

27 Feb 2025 — In the Linux kernel, the following vulnerability has been resolved: net_sched: sch_sfq: don't allow 1 packet limit The current implementation does not work correctly with a limit of 1. iproute2 actually checks for this and this patch adds the check in kernel as well. This fixes the following syzkaller reported crash: UBSAN: array-index-out-of-bounds in net/sched/sch_sfq.c:210:6 index 65535 is out of range for type 'struct sfq_head[128]' CPU: 0 PID: 2569 Comm: syz-executor101 Not tainted 5.10.0-smp-DEV #1 Ha... • https://git.kernel.org/stable/c/1da177e4c3f41524e886b7f1b8a0c1fc7321cac2 •
