kernel: filelock: fix potential use-after-free in posix_lock_inode

A use-after-free vulnerability was found in the Linux kernel in traceposixlockinode. This issue occurred when the request pointer was changed to point to a lock entry added to the inode's list. Before the tracepoint could fire, another task raced in and freed the lock...

The vulnerability of the posix_lock_inode() function in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the posixlockinode function in the fs/locks.c module of the Linux operating system is related to the reutilization of previously freed memory due to concurrent access to resources. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...

ggit is vulnerable to Arbitrary Argument Injection via the clone() API

All versions of the package ggit are vulnerable to Arbitrary Argument Injection via the clone API, which allows specifying the remote URL to clone and the file on disk to clone to. The library does not sanitize for user input or validate a given URL scheme, nor does it properly pass command-line...

Fuzzing µC/OS protocol stacks, Part 3: TCP/IP server fuzzing, implementing a TAP driver

This is the final post in the three-part series that details techniques I used to fuzz two µC/OS protocol stacks: µC/TCP-IP and µC/HTTP-server. The first post highlighted code modifications necessary for developing a fuzzing harness tailored for the µC/HTTP-server. The second discussed a techniqu...
