CVE-2024-50100 USB: gadget: dummy-hcd: Fix "task hung" problem

In the Linux kernel, the following vulnerability has been resolved: USB: gadget: dummy-hcd: Fix "task hung" problem The syzbot fuzzer has been encountering "task hung" problems ever since the dummy-hcd driver was changed to use hrtimers instead of regular timers. It turns out that the problems ar...

kernel: USB: class: cdc-wdm: Fix CPU lockup caused by excessive log messages

A vulnerability was found in the Linux kernel's CDC WDM driver, where excessive logging in the interrupt-URB completion callback could lead to CPU lockups, which occurs when the driver rapidly resubmits interrupt URBs after receiving a -EPROTO status, causing a backlog of error messages that...
