CVE-2026-31413

CVE-2026-31413 — Linux kernel BPF verifier flaw (CVE-joined info from multiple sources) The issue arises in maybe_fork_scalars() when handling ARSH plus AND/OR with a constant in the BPF verifier. The code forks the verifier state; the pushed path previously used env->insn_idx + 1, so it re-ex...

Linux kernel 安全漏洞

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from a scalar fork logic error in the BPFOR instruction within the maybeforkscalars function. This error may...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description The Linux kernel contains a flaw in the BPF verifier related to unsound scalar forking in the maybe fork scalars function when handling BPF OR operations. Specifically, the function...

CVE-2026-5466

wolfSSL's ECCSI signature verifier wcVerifyEccsiHash decodes the r and s scalars from the signature blob via mpreadunsignedbin with no check that they lie in 1, q-1. A crafted forged signature could verify against any message for any identity, using only publicly-known constants...

wolfSSL（CyaSSL） 安全漏洞

wolfSSL CyaSSL is a small, portable embedded SSL programming library developed by the American company wolfSSL, aimed at developers working with embedded systems. There is a security vulnerability in wolfSSL, where the ECCSI signature verifier does not check the scalar range, allowing specially...

CVE-2026-3580

In wolfSSL 5.8.4, constant-time masking logic in sp256getentry2569 is optimized into conditional branches bnez by GCC when targeting RISC-V RV32I with -O3. This transformation breaks the side-channel resistance of ECC scalar multiplication, potentially allowing a local attacker to recover secret...
