DESCRIPTION
* CVE-2018-19824: Use-after-free when registering a malicious USB audio device.
A wrong error handling when registering a malicious USB audio device
exposing 0 interface could lead to a use-after-free. A local attacker
could use this flaw to cause a denial-of-service.
* CVE-2019-3846: Heap overflow when parsing BSS descriptor in Marvell WiFi-Ex driver.
A missing check on user input when parsing BSS descriptor in Marvell
WiFi-Ex driver could let a local attacker cause a heap overflow and a
denial-of-service.
* CVE-2019-9503: Denial-of-service when receiving firmware event frames over a Broadcom WLAN USB dongle.
A failure to validate firmware event frames received over a Broadcom
WLAN USB dongle could let a remote attacker cause a denial-of-service.
* CVE-2019-9500: Potential heap overflow in Broadcom FullMAC WLAN driver.
A missing length check in the brcmfmac driver can lead to a buffer
overflow on the heap. This could cause a system to exhibit unexpected
behavior, and could potentially lead to a denial-of-service.
* CVE-2019-11487: Invalid memory access when overflowing pages refcount.
A reference count issue could let an attacker overflow pages reference
count and leads to invalid memory accesses. A local attacker could use
this flaw to cause a denial-of-service.
* CVE-2019-3887: Denial-of-service when running a nested guest in KVM.
A missing check when running a nested guest in KVM could let a L1 guest
access x2APIC Machine Specific Register (MSR) using a L2 guest. A local
attacker running from a L1 guest could use this flaw to cause a
denial-of-service.
