EL2 is\nleft pointing at the trans_pgd copy of the vectors, a page that\nswsusp_free() releases right after resume.\n\nSet the arguments up the same way __hyp_set_vectors() does.\n\nWithout this fix, Vladimir was able to trigger a hang when resuming from\nhibernation with CONFIG_PAGE_POISONING=y and page_poison=on.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":[],"vendors":[],"products":[],"references":[{"url":"https://git.kernel.org/stable/c/60a3c319f1127c4d247d4ed235c5d65376d5e745","tags":[]},{"url":"https://git.kernel.org/stable/c/6646418d1032cac25110526161f60d255ed08397","tags":[]},{"url":"https://git.kernel.org/stable/c/909e92423db7299e0206232051aa21fe129f65d0","tags":[]},{"url":"https://git.kernel.org/stable/c/955d86e5f3b95b731991fdb84966c50b16314629","tags":[]},{"url":"https://git.kernel.org/stable/c/d3f8f773312af69eaf4dda106d76d6d42e4362e5","tags":[]},{"url":"https://git.kernel.org/stable/c/e80ea8118a073a30ebe7a31bd78938c2b1751acc","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
