OpenTelemetry eBPF Instrumentation 安全漏洞

OpenTelemetry eBPF Instrumentation is an open-source, eBPF-based lightweight telemetry data collection tool developed by OpenTelemetry. Versions of OpenTelemetry eBPF Instrumentation prior to 0.9.0 contained security vulnerabilities. These vulnerabilities stemmed from the Java TLS ioctl probe usi...

Uncontrolled Resource Consumption

go.opentelemetry.io/obi is vulnerable to Uncontrolled Resource Consumption. The vulnerability is due to inefficient processing of BPF probe run-count deltas during histogram observation replay, which allows an attacker to trigger excessive CPU consumption on busy systems, leading to a...

Linux Distros Unpatched Vulnerability : CVE-2026-45933

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - bpf: Preserve id of register in synclinkedregs synclinkedregs copies the id of knownreg to reg when propagating bounds of knownreg to reg using the off of...

SUSE CVE-2026-45886

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix bpfxdpstorebytes proto for read-only arg While making some maps in Cilium read-only from the BPF side, we noticed that the bpfxdpstorebytes proto is incorrect. In particular, the verifier was throwing the following error...

SUSE CVE-2026-45903

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix memory access flags in helper prototypes After commit 37cce22dbd51 "bpf: verifier: Refactor helper access type tracking", the verifier started relying on the access type flags in helper function prototypes to perform...

CVE-2026-45903

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. This vulnerability occurs because several BPF helper functions lack proper memory access flags, such as MEMRDONLY or MEMWRITE. Consequently, the verifier may incorrectly assume that buffer contents remain unchanged across...

CVE-2026-45933

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. The synclinkedregs function fails to preserve the register ID during bounds propagation, which can lead to incorrect register state. This issue may allow a local attacker to trigger a 'division by zero' error, resulting i...

Linux Distros Unpatched Vulnerability : CVE-2026-45951

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - bpf: Fix a potential use-after-free of BTF object Refcounting in the checkpseudobtfid function is incorrect: the checkpseudobtfid function might get called with...

CVE-2026-45951

A flaw was found in the Linux kernel, specifically within its BPF Berkeley Packet Filter subsystem. This vulnerability, a use-after-free, arises from incorrect reference counting in the checkpseudobtfid function. It allows a local attacker to potentially corrupt memory, which could lead to...

EUVD-2026-32255

In the Linux kernel, the following vulnerability has been resolved: bpf: Limit bpf program signature size Practical BPF signatures are significantly smaller than KMALLOCMAXCACHESIZE Allowing larger sizes opens the door for abuse by passing excessive size values and forcing the kernel into expensi...

EUVD-2026-32393

In the Linux kernel, the following vulnerability has been resolved: bpf: Require frozen map for calculating map hash Currently, bpfmapgetinfobyfd calculates and caches the hash of the map regardless of the map's frozen state. This leads to a TOCTOU bug where userspace can call BPFOBJGETINFOBYFD t...

CVE-2026-45971

CVE-2026-45967

In the Linux kernel, the following vulnerability has been resolved: bpf: Return proper address for non-zero offsets in insn array The mapdirectvalueaddr function of the instruction array map incorrectly adds offset to the resulting address. This is a bug, because later the resolvepseudoldimm64...

CVE-2026-45951

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix a potential use-after-free of BTF object Refcounting in the checkpseudobtfid function is incorrect: the checkpseudobtfid function might get called with a zero refcounted btf. Fix this, and patch related code accordingly...

CVE-2026-45932

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix tcx/netkit detach permissions when prog fd isn't given This commit fixes a security issue where BPFPROGDETACH on tcx or netkit devices could be executed by any user when no program fd was provided, bypassing permission...
