Details

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

Severity

5.5 (Medium)
