Vulnerability in the Sun ZFS Storage Appliance product of Oracle Systems (component: Core). The supported version that is affected is 8.8.60. Difficult to exploit vulnerability allows unauthenticated attacker with network access via HTTP to compromise Sun ZFS Storage Appliance. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of Sun ZFS Storage Appliance. CVSS 3.1 Base Score 5.9 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H).

Ubuntu Security Notice 6385-1 - It was discovered that some AMD x86-64 processors with SMT enabled could speculatively execute instructions using a return address from a sibling thread. A local attacker could possibly use this to expose sensitive information. William Zhao discovered that the Traffic Control subsystem in the Linux kernel did not properly handle network packet retransmission in certain situations. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6340-1 - Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of service. Zi Fan Tan discovered that the binder IPC implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly execute arbitrary code.

A use-after-free vulnerability in the Linux kernel's net/sched: sch_hfsc (HFSC qdisc traffic control) component can be exploited to achieve local privilege escalation. If a class with a link-sharing curve (i.e. with the HFSC_FSC flag set) has a parent without a link-sharing curve, then init_vf() will call vttree_insert() on the parent, but vttree_remove() will be skipped in update_vf(). This leaves a dangling pointer that can cause a use-after-free. We recommend upgrading past commit b3d26c5702c7d6c45456326e56d2ccf3f103e60f.

Debian Linux Security Advisory 5480-1 - Several vulnerabilities have been discovered in the Linux kernel that may lead to a privilege escalation, denial of service or information leaks.
