CVE-2024-56696

Estado: ModificadaMedia (5.5)—

In the Linux kernel, the following vulnerability has been resolved:

ALSA: core: Fix possible NULL dereference caused by kunit_kzalloc()

kunit_kzalloc() may return a NULL pointer, dereferencing it without NULL check may lead to NULL dereference. Add NULL checks for all the kunit_kzalloc() in sound_kunit.c

CVSS

Probabilidad de explotación (EPSS)
