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，已修复以下漏洞： arm64: hibernate: 将 HVC_SET_VECTORS 参数传递给恢复阶段的 HVC 调用 在 函数中，虽然会通过 HVC（Hypervisor Call）重新安装恢复后的内核的 hyp stub 向量表，但并未传递必要的参数。具体而言，未将 x0 寄存器设置为 ，也未将 x1 寄存器设置为向量表地址。这导致 stub 分派逻辑未正确执行，直接返回而未能写入 寄存器。结果是 EL2 级别仍指向 中向量表的副本，而该页内存会在恢复完成后立即被 释放。 本修复方

Vulnerability Title
arm64: hibernate: pass HVC_SET_VECTORS args to the resume hvc
Source: CVE Program / CVE List V5
Vulnerability Description
In the Linux kernel, the following vulnerability has been resolved:
arm64: hibernate: pass HVC_SET_VECTORS args to the resume hvc
swsusp_arch_suspend_exit() reinstalls the restored kernel's hyp stub
vectors with an hvc, but never passes the arguments. x0 is not set to
HVC_SET_VECTORS and x1 is not set to the vector address, so the stub
dispatch falls through and returns without writing vbar_el2. EL2 is
left pointing at the trans_pgd copy of the vectors, a page that
swsusp_free() releases right after resume.
Set the arguments up the same way __hyp_set_vectors() does.
Without this fix, Vladimir was able to trigger a hang when resuming from
hibernation with CONFIG_PAGE_POISONING=y and page_poison=on.
