• CVE-2019-14901: A heap overflow flaw was found in the Marvell WiFi chip driver. The vulnerability allowed a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root.

These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free (bnc#1155897).

• CVE-2019-14901: A heap overflow flaw was found in the Linux kernel in Marvell WiFi chip driver. The vulnerability allowed a remote attacker to cause a system crash, resulting in a denial of service, or execute arbitrary code. The highest threat with this vulnerability is with the availability of the system. If code execution occurs, the code will run with the permissions of root. This will affect both confidentiality and integrity of files on the system (bnc#1157042).
• CVE-2019-14895: A heap-based buffer overflow was discovered in the Linux kernel in Marvell WiFi chip driver. The flaw could occur when the station attempts a connection negotiation during the handling of the remote devices country settings. This could have allowed the remote device to cause a denial of service (system crash) or possibly execute arbitrary code (bnc#1157158).
• CVE-2019-18660: The Linux kernel on powerpc allowed Information Exposure because the Spectre-RSB mitigation is not in place for all applicable CPUs. This is related to arch/powerpc/kernel/entry_64.S and arch/powerpc/kernel/security.c (bnc#1157038).

It is exploitable for privilege escalation on some Linux distributions where local users have /dev/video0 access, but only if the driver happens to be loaded. There are multiple race conditions during streaming stopping in this driver (part of the V4L2 subsystem). These issues are caused by wrong mutex locking in vivid_stop_generating_vid_cap(), vivid_stop_generating_vid_out(), sdr_cap_stop_streaming(), and the corresponding kthreads. At least one of these race conditions leads to a use-after-free (bnc#1155897).
