CVE-2026-63865
개요
A flaw was found in the Linux kernel. The Berkeley Packet Filter (BPF) Linux Security Modules (LSM) feature incorrectly registered certain hooks, task_to_inode and inet_conn_established, as available for sleepable programs. These hooks are invoked in critical system contexts where program sleeping is not allowed. An attacker could potentially exploit this by loading a malicious BPF LSM program, leading to system instability or a kernel crash.
CVSS (Common Vulnerability Scoring System) 점수 세부 사항
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
