CVE-2026-92517

A flaw was found in the Linux kernel's Berkeley Packet Filter (BPF) subsystem, specifically in the handling of extable entries for arena load_acquire operations on RISC-V architecture. Due to improper exception handling, a stale register value on fault can be leaked through a map, potentially leading to information disclosure. Additionally, a missing extable entry can cause a kernel crash, resulting in a Denial of Service (DoS). A local attacker could exploit this vulnerability to gain access to sensitive kernel memory or cause system instability.
