A flaw was found in the Linux kernel's ksmbd, a high-performance in-kernel SMB server. The specific flaw exists within the processing of SMB2_SESSION_SETUP commands. The issue results from the lack of proper locking when performing operations on an object. An attacker can leverage this vulnerability to execute code in the context of the kernel.

The Linux kernel allows userspace processes to enable mitigations by calling prctl with PR_SET_SPECULATION_CTRL which disables the speculation feature as well as by using seccomp. We had noticed that on VMs of at least one major cloud provider, the kernel still left the victim process exposed to attacks in some cases even after enabling the spectre-BTI mitigation with prctl. The same behavior can be observed on a bare-metal machine when forcing the mitigation to IBRS on boot command line. This happened because when plain IBRS was enabled (not enhanced IBRS), the kernel had some logic that determined that STIBP was not needed. The IBRS bit implicitly protects against cross-thread branch target injection. However, with legacy IBRS, the IBRS bit was cleared on returning to userspace, due to performance reasons, which disabled the implicit STIBP and left userspace threads vulnerable to cross-thread branch target injection against which STIBP protects.

Exposure of Sensitive Information to an Unauthorized Actor vulnerability in ABB Flow-X firmware on Flow-X embedded hardware (web service modules) allows Footprinting.This issue affects Flow-X: before 4.0.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Themeum Tutor LMS allows SQL Injection.This issue affects Tutor LMS: from n/a through 2.1.10.

A feature in LXD (LP#1829071), affects the default configuration of Ubuntu Server which allows privileged users in the lxd group to escalate their privilege to root without requiring a sudo password.

A path traversal vulnerability affects yaffshiv YAFFS filesystem extractor. By crafting a malicious YAFFS file, an attacker could force yaffshiv to write outside of the extraction directory. This issue affects yaffshiv up to version 0.1 included, which is the most recent at time of publication.
