CVE-2025-37948

In the Linux kernel, the following vulnerability has been resolved: arm64: bpf: Add BHB mitigation to the epilogue for cBPF programs A malicious BPF program may manipulate the branch history to influence what the hardware speculates will happen next. On exit from a BPF program, emit the BHB mititgation sequence. This is only applied for 'classic' cBPF programs that are loaded by seccomp.

Summary
  • (es) En el kernel de Linux, se ha resuelto la siguiente vulnerabilidad: arm64: bpf: Añadir mitigación de BHB al epílogo de programas cBPF. Un programa BPF malicioso puede manipular el historial de ramificaciones para influir en lo que el hardware especula que ocurrirá a continuación. Al salir de un programa BPF, se emite la secuencia de mitigación de BHB. Esto solo se aplica a programas cBPF clásicos cargados por seccomp.
