15eaed3e014c6abcd7ef4aea5c724475e760f7f6f793ec69de76aed893e74d80Jann Horn discovered that the Berkeley Packet Filter (BPF) implementation in the Linux kernel improperly performed sign extension in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. It was discovered that a race condition leading to a use-after-free vulnerability existed in the ALSA PCM subsystem of the Linux kernel. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. Various other issues were also addressed.

e47605adb85ececbd4ae2974c9376652991663a139c1e597e8d245b3700d48a9Ubuntu Security Notice 3632-1 - It was discovered that a race condition leading to a use-after-free vulnerability existed in the ALSA PCM subsystem of the Linux kernel. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that the KVM implementation in the Linux kernel allowed passthrough of the diagnostic I/O port 0x80. An attacker in a guest VM could use this to cause a denial of service in the host OS. Various other issues were also addressed.
