  "description": "In the Linux kernel, the following vulnerability has been resolved:  crypto: ccp - Check for page allocation failure correctly in TIO  Sashiko notes:  \u003E if __snp_alloc_firmware_pages() returns NULL under memory pressure, is it \u003E safe to pass it directly to page_address()? \u003E \u003E On architectures without HASHED_PAGE_VIRTUAL, page_address(NULL) might \u003E compute a deterministic but invalid, non-zero virtual address. The \u003E subsequent if (tio_status) check would then evaluate to true, and \u003E sev_tsm_init_locked() would dereference the invalid pointer.  Indeed, page_address(NULL) will return non-NULL garbage here. Fix this by checking the page allocation itself for NULL, not the resulting virtual address.",
