CVE-2026-64507

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