CVE-2026-39883

A flaw was found in OpenTelemetry-Go. On BSD and Solaris platforms, a local attacker could exploit a vulnerability related to the kenv command. By manipulating the system's PATH environment variable, an attacker could achieve arbitrary code execution or privilege escalation, leading to a compromi...

CVE-2026-39883

OpenTelemetry-Go is the Go implementation of OpenTelemetry. From 1.15.0 to 1.42.0, the fix for CVE-2026-24051 changed the Darwin ioreg command to use an absolute path but left the BSD kenv command using a bare name, allowing the same PATH hijacking attack on BSD and Solaris platforms. This...

CVE-2026-39883

OpenTelemetry-Go versions 1.15.0–1.42.0 contain an incomplete fix for CVE-2026-24051: when addressing the Darwin ioreg command to use an absolute path, the BSD kenv command was left with a bare command name, enabling a PATH hijacking attack on BSD and Solaris platforms. The issue is resolved in O...

Name of the Vulnerable Software and Affected Versions OpenTelemetry-Go versions 1.15.0 through 1.42.0 Description The fix for a previous issue changed the path used for one command but left another command vulnerable to a PATH hijacking attack on BSD and Solaris platforms. Specifically, the kenv...

CVE-2026-31401

A flaw was found in the Linux kernel's Human Interface Device HID BPF Berkeley Packet Filter component. This vulnerability occurs in the hidhwrequest function, where an uncontrolled return value from dispatchhidbpfrawrequests can lead to a buffer overflow. This could allow a local attacker to cau...

CVE-2026-23412

A flaw was found in the Linux kernel's netfilter BPF Berkeley Packet Filter component. A local attacker could exploit this by initiating a concurrent process to dump hooks via nfnetlinkhooks, which triggers a use-after-free vulnerability. This could lead to system instability or a denial of servi...

New Whitepaper: Stealthy BPFDoor Variants are a Needle That Looks Like Hay

Executive Overview Advanced persistent threats APTs are constantly and consistently changing tactics as network defenders plug holes in defenses. Static indicators of compromise IoCs for the BPFDoor have been widely deployed, forcing threat actors to get creative in their use of this particular...
