A NULL pointer dereference was found in the Linux kernel's KVM when dirty ring logging is enabled without an active vCPU context. An unprivileged local attacker on the host may use this flaw to cause a kernel oops condition and thus a denial of service by issuing a KVM_XEN_HVM_SET_ATTR ioctl. This flaw affects Linux kernel versions prior to 5.17-rc1.

A flaw in grub2 was found where its configuration file, known as grub.cfg, is being created with the wrong permission set allowing non privileged users to read its content. This represents a low severity confidentiality issue, as those users can eventually read any encrypted passwords present in grub.cfg. This flaw affects grub2 2.06 and previous versions. This issue has been fixed in grub upstream but no version with the fix is currently released.

A NULL pointer dereference flaw was found in the btrfs_rm_device function in fs/btrfs/volumes.c in the Linux Kernel, where triggering the bug requires ‘CAP_SYS_ADMIN’. This flaw allows a local attacker to crash the system or leak kernel internal information. The highest threat from this vulnerability is to system availability.

There's a flaw in urllib's AbstractBasicAuthHandler class. An attacker who controls a malicious HTTP server that an HTTP client (such as web browser) connects to, could trigger a Regular Expression Denial of Service (ReDOS) during an authentication request with a specially crafted payload that is sent by the server to the client. The greatest threat that this flaw poses is to application availability.

An authenticated user can create a link with reflected XSS payload for actions’ pages, and send it to other users. Malicious code has access to all the same objects as the rest of the web page and can make arbitrary modifications to the contents of the page being displayed to a victim. This attack can be implemented with the help of social engineering and expiration of a number of factors - an attacker should have authorized access to the Zabbix Frontend and allowed network connection between a malicious server and victim’s computer, understand attacked infrastructure, be recognized by the victim as a trustee and use trusted communication channel.

An authenticated user can create a link with reflected Javascript code inside it for services’ page and send it to other users. The payload can be executed only with a known CSRF token value of the victim, which is changed periodically and is difficult to predict. Malicious code has access to all the same objects as the rest of the web page and can make arbitrary modifications to the contents of the page being displayed to a victim during social engineering attacks.
