  "details": "In the Linux kernel, the following vulnerability has been resolved:  bpf: Fix abuse of kprobe_write_ctx via freplace  uprobe programs are allowed to modify struct pt_regs.  Since the actual program type of uprobe is KPROBE, it can be abused to modify struct pt_regs via kprobe+freplace when the kprobe attaches to kernel functions.  For example,  SEC(\"?kprobe\") int kprobe(struct pt_regs *regs) { \treturn 0; }  SEC(\"?freplace\") int freplace_kprobe(struct pt_regs *regs) { \tregs-\u003edi = 0; \treturn 0; }  freplace_kprobe prog will attach to kprobe prog. kprobe prog will attach to a kernel function.  Without this patch, when the kernel function runs, its first arg will always be set as 0 via the freplace_kprobe prog.  To fix the abuse of kprobe_write_ctx=true via kprobe+freplace, disallow attaching freplace programs on kprobe programs with different kprobe_write_ctx values.",
