A vulnerability was found in btrfs_alloc_tree_b in fs/btrfs/extent-tree.c in the Linux kernel due to an improper lock operation in btrfs. In this flaw, a user with a local privilege may cause a denial of service (DOS) due to a deadlock problem.

An unprivileged write to the file handler flaw in the Linux kernel's control groups and namespaces subsystem was found in the way users have access to some less privileged process that are controlled by cgroups and have higher privileged parent process. It is actually both for cgroup2 and cgroup1 versions of control groups. A local user could use this flaw to crash the system or escalate their privileges on the system.

A use-after-free flaw was found in the add_partition in block/partitions/core.c in the Linux kernel. A local attacker with user privileges could cause a denial of service on the system. The issue results from the lack of code cleanup when device_add call fails when adding a partition to the disk.

The security landscape is dynamic, changing often and as a result, attack surfaces evolve. MSRC receives a wide variety of cases spanning different products, bug types and exploit primitives. One particularly interesting primitive we see is an arbitrary kernel pointer read. These often happen when kernel mode code does not validate that pointers read from attacker-controlled input actually point to the user-mode portion of the Virtual Address Space (VAS).

BigAnt Software BigAnt Server v5.6.06 was discovered to contain a Cross-Site Request Forgery (CSRF).

In Click Studios (SA) Pty Ltd Passwordstate 9435, users with access to a passwordlist can gain access to additional password lists without permissions. Specifically, an authenticated user who has write permissions to a password list in one folder (with the default permission model) can extend his permissions to all other password lists in the same folder.
