Reading and writing memory of other processes using fasttrap The /dev/fasttrap device for creating trap nodes in user-space processes for the pid and objc providers has the permissions 666. In contrast to /dev/dtrace, which is also 666, fasttrap lacks a permission check. This allows any process t...

STrace
STrace Steve's Tracer. A DTrace on windows syscall hook reimplementation. Think of this like a patchguard compatible SSDT hook, but without hacks. This doesn't support SSSDT win32k apis, as the DTrace system call APIs themselves do not support this additional table. Zw kernel apis can be traced i...
GLSA-202608-24 : DTrace: Multiple Vulnerabilities
The remote host is affected by the vulnerability described in GLSA-202608-24 DTrace: Multiple Vulnerabilities Multiple vulnerabilities have been discovered in DTrace. Please review the CVE identifiers referenced below for details. Tenable has extracted the preceding description block directly fro...
DTrace: Multiple Vulnerabilities
Background DTrace is a dynamic tracing tool for analysing or debugging the whole system. Specifically, dtprobed is a component of the DTrace system that keeps track of USDT probes within running processes, parsing and storing the DOF they provide for later consumption by dtrace proper. Descriptio...
CVE-2026-21996
An unprivileged attacker can reliably trigger a crash of the dtrace process with a malicious ELF binary due to an integer Divide-by-Zero in Pbuildfilesymtab...
CVE-2026-35233
An unprivileged attacker can craft a user-space process with a malicious ELF binary containing an out-of-range shlink field. When root-level dtrace attaches to -- or instruments -- that process via dtrace -p , pid probes, or USDT, the ELF parser reads heap memory beyond the allocated section cach...

CVE-2026-35233
CVE-2026-35233 is active in the Oracle Linux dtrace subsystem. An unprivileged user can craft a binary with an out-of-range sh_link, enabling an ELF parser to read memory beyond the allocated section cache due to missing bounds checks during object symbol table construction. This can cause a NULL...
