On Ubuntu kernels carrying both c914c0e27eb0 and "UBUNTU: SAUCE: overlayfs: Skip permission checking for trusted.overlayfs.* xattrs", an unprivileged user may set privileged extended attributes on the mounted files, leading them to be set on the upper files without the appropriate security checks. This module exploits this in order to achieve LPE.

The specific flaw exists within the Tablet Service. By creating a symbolic link, an attacker can abuse the service to create a file. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM.

The cause of the vulnerability is due to the lack of a strict bounds check for some fields in the Base Block for the base log file (BLF) in CLFS.sys. This issue can lead to a Privilege Escalation.

A flaw was found in the Linux kernel, where unauthorized access to the execution of the setuid file with capabilities was found in the Linux kernel OverlayFS subsystem in how a user copies a capable file from a nosuid mount into another mount. This uid mapping bug allows a local user to escalate their privileges on the system.

In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled.

HP Hardware Diagnostics EtdSupp driver is potentially vulnerable to buffer overflow and/or elevation of privilege.

The Common Log File System Driver (clfs.sys) present in Microsoft Windows is vulnerable to a memory corruption vulnerability. This module allows a local unprivileged user to execute arbitrary code with SYSTEM privileges by creating a specially crafted base log file.

The cause of the vulnerability is due to the lack of a strict bounds check for the SignaturesOffset field in the Base Block for the base log file (BLF) in CLFS.sys. This issue can lead to a Privilege Escalation.This version adds support for Windows 10 and some Windows servers.

The Ancillary Function Driver (AFD.sys) present in Microsoft Windows is vulnerable to an arbitrary memory overwrite. This module allows a local unprivileged user to execute arbitrary code with SYSTEM privileges by sending a specially crafted IOCTL to the vulnerable driver.

The cause of the vulnerability is due to the lack of a strict bounds check for the SignaturesOffset field in the Base Block for the base log file (BLF) in CLFS.sys. This issue can lead to a Privilege Escalation.
