CVE-2022-49552

CVE-2022-49552 affects the Linux kernel. The issue arises in the BPF JIT blinding logic where ld_imm64 addresses to subprogs are misidentified as normal instructions, causing a page fault in kernel mode. The root cause is the two-phase JIT process for subprogs; the first phase blinds and the seco...
