About vulnerability
In the Linux kernel, the following vulnerability has been resolved:
mISDN: Fix memory leak in dsp_pipeline_build()
dsp_pipeline_build() allocates dup pointer by kstrdup(cfg), but then it updates dup variable by strsep(&dup, “|”). As a result when it calls kfree(dup), the dup variable contains NULL.
Found by Linux Driver Verification project (linuxtesting.org) with SVACE.
