In the Linux kernel, the following vulnerability has been resolved: USB: gadget: Fix use-after-free Read in usb_udc_uevent() The syzbot fuzzer found a race between uevent callbacks and gadget driver unregistration that can cause a use-after-free bug: --------------------------------------------------------------- BUG: KASAN: use-after-free in usb_udc_uevent+0x11f/0x130 drivers/usb/gadget/udc/core.c:1732 Read of size 8 at addr ffff888078ce2050 by task udevd/2968 CPU: 1 PID: 2968 Comm: udevd Not tainted 5.19.0-rc4-next-20220628-syzkaller #0 Hardware name: Google Google Compute Engine/Google Compute Engine, BIOS Google 06/29/2022 Call Trace: <TASK> __dump_stack lib/dump_stack.c:88 [inline] dump_stack_lvl+0xcd/0x134 lib/dump_stack.c:106 print_address_description mm/kasan/report.c:317 [inline] print_report.cold+0x2ba/0x719 mm/kasan/report.c:433 kasan_report+0xbe/0x1f0 mm/kasan/report.c:495 usb_udc_uevent+0x11f/0x130 drivers/usb/gadget/udc/core.c:1732 dev_uevent+0x290/0x770 drivers/base/core.c:2424 --------------------------------------------------------------- The bug occurs because usb_udc_uevent() dereferences udc->driver but does so without acquiring the udc_lock mutex, which protects this field. If the gadget driver is unbound from the udc concurrently with uevent processing, the driver structure may be accessed after it has been deallocated. To prevent the race, we make sure that the routine holds the mutex around the racing accesses.

  - USB: gadget: Fix use-after-free Read in usb_udc_uevent() The syzbot fuzzer found a race between uevent     callbacks and gadget driver unregistration that can cause a use-after-free bug:

    --------------------------------------------------------------- The bug occurs because usb_udc_uevent()     dereferences udc->driver but does so without acquiring the udc_lock mutex, which protects this field. If     the gadget driver is unbound from the udc concurrently with uevent processing, the driver structure may be     accessed after it has been deallocated. To prevent the race, we make sure that the routine holds the mutex     around the racing accesses. (CVE-2022-49980)

Note that Nessus relies on the presence of the package as reported by the vendor.
