FreeBSD Kernel Hacking Exercises from Joseph Kong's Designing BSD Rootkits, updated for FreeBSD 11/12. Even though the book is over 10 years old, it's highly recommended as it's quite a challenge to update the source code provided in the book to work on modern releases. Further Resources:...
FreeBSD : FreeBSD -- Kernel use-after-free via the SNDCTL_DSP_SYNCSTART ioctl (226751fb-a0fe-11f1-ae1f-bc241121aa0a)
The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 226751fb-a0fe-11f1-ae1f-bc241121aa0a advisory. The implementation of this ioctl attempts to acquire locks on all channels in a sync group. If locking ...
FreeBSD -- Kernel use-after-free via tty ioctls
Problem Description: The TIOCSCTTY ioctl handler drops the tty lock in order to acquire the process tree lock. After reacquiring the tty lock, the handler did not revalidate the state of the terminal, and could proceed to link a terminal that was concurrently being destroyed to the calling proces...
CVE-2026-58083
While the kernel was copying knotes during fork, a knote with a timer-based filter could fire and be enqueued on the kqueue's active list before the copy was complete. The copy routine did not account for this and could enqueue the new knote a second time, corrupting the active list. In addition,...
FreeBSD Kernel Heap Buffer Overflow DoS
The vulnerability of the dspmmapsingle function in the operating system kernels of FreeBSD is related to reading data beyond the allowed range of memory. Exploiting this vulnerability can allow an attacker to cause a service failure...
FreeBSD : FreeBSD-kernel -- Kernel stack disclosure in 32-bit compatibility support (43f9ca02-74e3-11f1-958d-bc241121aa0a)
The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the 43f9ca02-74e3-11f1-958d-bc241121aa0a advisory. The compat32 kevent handler translates a 64-bit kevent struct into a stack- declared 32-bit struct. It...
PT-2026-71932
Name of the Vulnerable Software and Affected Versions FreeBSD kernel affected versions not specified Description When auditing a system call executed via ptracePT SC REMOTE, the kernel passes the return value of an internal setup function to AUDIT SYSCALL EXIT instead of the actual result of the...
PT-2026-70015
Name of the Vulnerable Software and Affected Versions FreeBSD kernel affected versions not specified Description The kernel functions implementing unlinkat2 and funlinkat2 fail to pass the AT RESOLVE BENEATH flag to the underlying path lookup process. Although the flag is validated, it is silentl...
FreeBSD Security Advisory - FreeBSD-SA-26:13.exec
FreeBSD Security Advisory - An operator precedence bug in the kernel results in a scenario where a buffer overflow causes attacker-controlled data to overwrite adjacent execve2 argument buffers...
FreeBSD Kernel Unauthorized Access
The vulnerability of the FreeBSD operating system’s kernel is related to the use of an erroneous operator. Exploiting this vulnerability can allow a remote attacker to gain unauthorized access to protected information...
FreeBSD kernel Heap Buffer Overflow DoS
The vulnerability of the rtsockmsgbuffer function in the kernel of the FreeBSD operating system is related to writing beyond the buffer’s memory boundaries. Exploiting this vulnerability can allow a remote attacker to cause a service failure...
FreeBSD kernel File System Access
The vulnerability of FreeBSD operating systems lies in the insecure management of privileges. Exploiting this vulnerability can allow a remote attacker to gain access to the file system...
PT-2026-21884
Name of the Vulnerable Software and Affected Versions FreeBSD affected versions not specified Description The rtsock msg buffer function copies sockaddr structures into a sockaddr storage structure on the stack without proper validation of the source sockaddr length. This can lead to a 127-byte...
FreeBSD Kernel Buffer Overflow
The vulnerability of the FreeBSD operating system’s kernel implementation is related to buffer overflow in the stack. Exploiting this vulnerability allows a remote attacker to execute arbitrary code...
