CVE-2026-45680

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, OBI replays BPF probe hits into histogram observations by looping once per recorded run count. On busy systems, the run-count delta can become very large, causing the...

EUVD-2026-34082

A vulnerability has been found in cilium ebpf up to 0.21.0. This affects the function loadRawSpec of the file btf/btf.go of the component LoadCollectionSpec/LoadCollectionSpecFromReader. Such manipulation of the argument offset leads to integer overflow. The attack can only be performed from a...

CVE-2026-45679

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, OBI exports raw Redis error text as the span status message. Because Redis error replies can contain attacker-controlled or sensitive values, this behavior can exfiltrate...

CVE-2026-45681

OpenTelemetry eBPF Instrumentation provides eBPF instrumentation based on the OpenTelemetry standard. Prior to version 0.9.0, the per-CPU message-buffer fallback path uses a 256-byte backup buffer but preserves the original payload size, which can be up to 8KB. If a CPU mismatch occurs, OBI can...

CVE-2026-45686

OpenTelemetry eBPF Instrumentation contains a remote integer overflow in OBI’s memcached text protocol parser (memcached_detect_transform.go) that can crash the OBI process and cause denial of service. Affected versions are 0.7.0 through before 0.9.0; the parser accepts large values for storage ...

CVE-2026-45680

CVE-2026-45680 affects OpenTelemetry eBPF Instrumentation (OBI) prior to version 0.9.0. The root cause is an unbounded delta in calculateStats(), where bp.runCount − bp.prevRunCount is used without a cap, causing the exporter to loop over probe hits for large run-count deltas. This can lead to hi...

SUSE CVE-2026-3593

A use-after-free vulnerability exists within the DNS-over-HTTPS implementation. This issue affects BIND 9 versions 9.20.0 through 9.20.22, 9.21.0 through 9.21.21, and 9.20.9-S1 through 9.20.22-S1. BIND 9 versions 9.18.0 through 9.18.48 and 9.18.11-S1 through 9.18.48-S1 are NOT affected...

SUSE CVE-2026-45927

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...

SUSE CVE-2026-45971

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...

CVE-2026-45927

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability, a Time-of-check to time-of-use TOCTOU bug, allows a local attacker to modify the contents of a BPF map after its hash has been calculated but before it is frozen. Consequently, a trusted loader could ...

CVE-2026-45967

A flaw was found in the Linux kernel. Specifically, a bug in the mapdirectvalueaddr function, which is part of the Berkeley Packet Filter BPF instruction array map, leads to incorrect address calculations when dealing with non-zero offsets. This issue could result in the kernel accessing unintend...

CVE-2026-45971

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF component. A local attacker could exploit this vulnerability by providing an excessively large BPF program signature. This could force the kernel into expensive memory allocation paths, potentially leading to resource exhaustion an...

EUVD-2026-32251

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...

UBUNTU-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...

UBUNTU-CVE-2026-45933

In the Linux kernel, the following vulnerability has been resolved: 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 knownreg, but when knownreg was linked to reg like: knownreg = reg ; both...

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...

CVE-2026-45839

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter CO-RE Compile Once - Run Everywhere accessor parsing. A local attacker with CAPBPF capabilities could craft a malicious BPF program that uses negative CO-RE accessor indices. This input validation vulnerability allows for an...

CVE-2026-45838

A flaw was found in the Linux kernel. Specifically, within the Berkeley Packet Filter BPF component, an error in the cgroupstoragegetnextkey function's end-of-list detection mechanism can cause the system to read from an invalid memory location. This incorrect handling may lead to internal map...

CVE-2026-45971

The CVE-2026-45971 entry concerns the Linux kernel: a vulnerability in limiting the bpf program signature size. The issue arises because allowing larger sizes can lead to abuse by passing oversized values, driving the kernel into expensive allocation paths such as kmalloc_large or vmalloc. The av...
