DEBIAN-CVE-2026-98589
In the Linux kernel, the following vulnerability has been resolved: bpf: Reject pkt arguments in mutating subprogs The verifier tracks changes in how PTRTOPACKET registers' bounds are modified across subprog boundaries. PTRTOPACKET registers are actually passed as PTRTOMEM, which is assumed valid...
CVE-2022-23222
CVE-2022-23222 Click here if you just wanna build and run the dang thing. What follows is more or less a translation of the Chinese writeup, available here. We'll use the mainline kernel code for version 5.13.0 as a reference. There is a mismatch in available pointer types and the function that...
CVE-2026-98590
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix bpfsock context code generation Currently, the ctx access code reads the rxqueuemapping field with either a 4-byte or 2-byte load. The rest of the bits in the register are marked known zero by the verifier. However, the...

CVE-2026-98590
The Linux kernel contains a vulnerability in the bpf_sock context code generation. The issue arises because the ctx access code reads the rx_queue_mapping field using a 4-byte or 2-byte load, but the emitted code uses BPF_MOV_IMM64 for certain special values (like -1). This causes sign-extension,...

CVE-2017-16995
The latest version of Ubuntu Ubuntu 16.04 has a high-risk local privilege escalation vulnerability, numbered CVE-2017-16995. This vulnerability exists in the Linux kernel system that calls eBPF bpf2. When a user provides a malicious BPF program, the eBPF verifier module generates a calculation...
Linux Distros Unpatched Vulnerability : CVE-2026-98589

PT-2026-116847
In the Linux kernel, the following vulnerability has been resolved: bpf: Make post-verification instruction rewrites killable After do check returns, the verifier runs several instruction rewrite passes. Some of them patch or remove one instruction at a time. Each operation moves the remaining...
Linux Kernel Security Vulnerabilities
Versions of the Linux kernel prior to 7.2.9 have a security vulnerability. This vulnerability arises from the BPF verifier failing to reject the transfer of the PTRTOPACKET pointer to procedures that may modify data packets, potentially causing the data packet memory area to become invalid...
Linux Kernel Security Vulnerabilities
The Linux kernel version 5.8 contains a security vulnerability. This vulnerability stems from the bpfsock context code, which fails to ensure that the width of the read value is consistent with the assumptions of the verifier when reading the rxqueuemapping field. As a result, the values of runti...
CVE-2026-7878-eBPF-Verifier-Type-Confusion-Kernel-Memory-Read-Write
6. CVE-2026-7878 – eBPF Verifier Type Confusion → Kernel Memory Read/Write Overview A subtle integer overflow in the eBPF verifier’s bounds tracking allows an attacker to craft an eBPF program that accesses out‑of‑bounds kernel memory. Severity: Critical Kernel Privilege Escalation User‑mode eBPF...

AuthProof SDK AuthProof is an audit and attribution layer for AI agents. It lets you prove what a user authorized before the agent acted, and it records what the agent actually did against that authorization. The mechanism is simple. The user signs a delegation receipt with their own private key...
Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1
In the Linux kernel, the following vulnerability has been resolved: BPF: Allow deletion from sockmap/sockhash only if updating is allowed. We have received a surge in reports from syzkaller instances where a BPF program attached to a tracepoint triggered a locking rule violation by performing a...
Astra Linux – Vulnerability in Linux 5.10
The checkaluop function in kernel/bpf/verifier.c in the Linux kernel, as of v5.16-rc5, did not properly update the bounds when handling the mov32 instruction. This issue allows local users to obtain potentially sensitive address information, also known as a “pointer leak.”...
CVE-2026-31413-BPF-Container-Escape
CVE-2026-31413: One Byte in the BPF Verifier to Container Escape I found a soundness bug in the Linux BPF verifier - a + 1 in a pushstack call that causes the verifier to skip an ALU instruction on a forked path. For BPFOR, this means the verifier tracks dst = 0 while the CPU computes 0 | K = K. ...
