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.
An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
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 BLF file.
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.
An attacker who successfully exploited the vulnerability could execute code with elevated permissions.
This module uses NTLM reflection to achieve a SYSTEM handle for elevation of privilege.
This module can be used to perform a privilege escalation using a misconfiguration on the Object Authorities of a User profile.
This module exploits an Arbitrary File Deletion performed by an unprivileged user in any protected folder. Before deleting the file, this module backups the file in the user temp folder
A use-after-free flaw was found in route4_change in the net/sched/cls_route.c filter implementation in the Linux kernel. This flaw allows a local user to crash the system and possibly lead to a local privilege escalation problem.
