Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.
在 Linux 内核中，以下漏洞已得到修复： bpf, x86：修复 128 位参数对应的 trampoline 栈大小问题 可接受最大 16 字节的函数参数，因此像 这样的 128 位标量传入 x86 trampoline 时，其 为 16。然而，当前实现假设一个 参数只需占用一个寄存器，导致用于保存寄存器的栈区域分配不足，使得 函数会覆盖相邻的栈槽位。 修复方案：根据每个参数的 动态计算所需的寄存器数量，以正确处理 128 位参数。

Vulnerability Title
bpf, x86: Fix trampoline stack size for 128-bit arguments
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
bpf, x86: Fix trampoline stack size for 128-bit arguments
btf_distill_func_proto() accepts a function argument up to 16 bytes, so a
128-bit scalar such as __int128 reaches the x86 trampoline with
arg_size == 16. But the current implementation assumes an __int128
argument only needs one register, so the register save area is
under-allocated and save_args() overwrites adjacent stack slots.
Compute the register count from arg_size for all arguments to fix it.
