CVE-2026-99092

A flaw was found in the Linux kernel's RISC-V architecture. An issue in the instruction patching mechanism improperly handles memory allocated for Berkeley Packet Filter Just-In-Time (BPF JIT) compilation under specific kernel memory configurations. A local user capable of loading BPF programs can cause the kernel to attempt to write to read-only memory. This operation triggers kernel page faults and warnings, preventing programs from compiling and resulting in a denial of service (DoS).
