Summary
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Intel: hda: Use devm_kstrdup() to avoid memleak.
sof_pdata->tplg_filename can have address allocated by kstrdup()
and can be overwritten. Memory leak was detected with kmemleak:
unreferenced object 0xffff88812391ff60 (size 16):
comm "kworker/4:1", pid 161, jiffies 4294802931
hex dump (first 16 bytes):
