Description Rohit Keshri 2024-03-06 10:46:30 UTC

A native Spectre-v2 exploit against the Linux kernel on last-generation Intel CPUs, based on the recent BHI variant and able to leak arbitrary kernel memory at 3.5 kB/sec. In this flaw a number of gadgets and exploitation techniques to bypass the recent FineIBT mitigation, along with a case study on a 13th Gen Intel CPU that can leak kernel memory at 18 bytes/sec.
