Deskripsi CVE
In the Linux kernel, the following vulnerability has been resolved:
USB: gadget: Fix the memory leak in raw_gadget driver
Currently, increasing raw_dev->count happens before invoke the
raw_queue_event(), if the raw_queue_event() return error, invoke
raw_release() will not trigger the dev_free() to be called.
[ 268.905865][ T5067] raw-gadget.0 gadget.0: failed to queue event
[ 268.912053][ T5067] udc dummy_udc.0: failed to start USB Raw Gadget: -12
[ 268.918885][ T5067] raw-gadget.0: probe of gadget.0 failed with error -12
[ 268.925956][ T5067] UDC core: USB Raw Gadget: couldn't find an available UDC or it's busy
[ 268.934657][ T5067] misc raw-gadget: fail, usb_gadget_register_driver returned -16

This commit therefore invoke kref_get() under the condition that
raw_queue_event() return success.
Informasi CVE
EPSS
EPSS adalah model penilaian yang memprediksi kemungkinan suatu kerentanan dieksploitasi.
Skor EPSS
Model EPSS menghasilkan skor probabilitas antara 0 dan 1 (0 hingga 100%). Semakin tinggi skor, semakin besar probabilitas bahwa suatu kerentanan akan dieksploitasi.
Persentil EPSS
Persentil digunakan untuk meranking CVE berdasarkan skor EPSS mereka. Misalnya, CVE di persentil ke-95 berdasarkan skor EPSS-nya lebih mungkin dieksploitasi daripada 95% CVE lainnya. Dengan demikian, persentil digunakan untuk membandingkan skor EPSS suatu CVE dengan CVE lainnya.
