CVE-2026-64507
Description
AI Translation Available
In the Linux kernel, the following vulnerability has been resolved:
x86/bugs: Enable IBPB flush on BPF JIT allocation
Enable hardening against JIT spraying when Spectre-v2 mitigations are in
use. Specifically, issue an IBPB flush on BPF JIT memory reuse. Skip
enabling the IBPB flush if the BPF dispatcher is already using a retpoline
sequence.
This hardening applies only when BPF-JIT is in use. Guard the enabling
under CONFIG_BPF_JIT so that bugs.c still builds with CONFIG_BPF_JIT=n.
