CVE-2022-48760

In the Linux kernel, the following vulnerability has been resolved: USB: core: Fix hang in usbkillurb by adding memory barriers The syzbot fuzzer has identified a bug in which processes hang waiting for usbkillurb to return. It turns out the issue is not unlinking the URB; that works just fine...

CVE-2022-48760

The CVE-2022-48760 entry concerns a Linux kernel USB subsystem hang in usb_kill_urb() caused by memory-access ordering issues (SB pattern) between usb_kill_urb() and __usb_hcd_giveback_urb() on SMP systems. The vulnerability is fixed by adding memory barriers, specifically using the smp_mb__after...
