kernel: x86/bugs: Enable IBPB flush on BPF JIT allocation
A flaw was found in the Linux kernel. This vulnerability involves an incomplete defense against Spectre-v2, a type of attack that can expose sensitive information by exploiting how modern processors predict future operations. Specifically, when the Berkeley Packet Filter BPF Just-In-Time JIT...

New Spectre-v2 BTR Attack Leaks Linux Memory Despite Existing Defenses
A group of academics from VUSec and Scuola Superiore Sant'Anna have disclosed details of a new Spectre CPU vulnerability variant that affects Just-In-Time JIT engines present in web browsers, language runtimes, and the operating system kernel, across multiple CPU vendors. The new Spectre v2 varia...
From Silicon to Boot Code: Extending Automated Program Repair to Firmware-Layer Security Workarounds
Automated program repair APR research has been constrained to design time. Current techniques localize and fix bugs in RTL or HLS designs before a chip reaches production. Once a hardware vulnerability surfaces post-silicon, the patch must be manually generated: existing automation addresses patc...
