CVE-2021-46924

In the Linux kernel, the following vulnerability has been resolved: NFC: st21nfca: Fix memory leak in device probe and remove 'phy-pendingskb' is alloced when device probe, but forgot to free in the error handling path and remove path, this cause memory leak as follows: unreferenced object...

kernel: ASoC: mediatek: mt8173: Fix refcount leak in mt8173_rt5650_rt5676_dev_probe

A flaw was found in the mt8173-rt5650-rt5676 module in the Linux kernel. A missing decrement of the reference count when an error occurs will cause a memory leak, potentially impacting system performance and resulting in a denial of service...

kernel: ALSA: bcd2000: Fix a UAF bug on the error path of probing

In the Linux kernel, the following vulnerability has been resolved: ALSA: bcd2000: Fix a UAF bug on the error path of probing When the driver fails in sndcardregister at probe time, it will free the 'bcd2k-midiouturb' before killing it, which may cause a UAF bug. The following log can reveal it:...
