| "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nmemblock: Accept allocated memory before use in memblock_double_array()\n\nWhen increasing the array size in memblock_double_array() and the slab\nis not yet available, a call to memblock_find_in_range() is used to\nreserve/allocate memory. However, the range returned may not have been\naccepted, which can result in a crash when booting an SNP guest:\n\n RIP: 0010:memcpy_orig+0x68/0x130\n Code: ...\n RSP: 0000:ffffffff9cc03ce8 EFLAGS: 00010006\n RAX: ff11001ff83e5000 RBX: 0000000000000000 RCX: fffffffffffff000\n RDX: 0000000000000bc0 RSI: ffffffff9dba8860 RDI: ff11001ff83e5c00\n RBP: 0000000000002000 R08: 0000000000000000 R09: 0000000000002000\n R10: 000000207fffe000 R11: 0000040000000000 R12: ffffffff9d06ef78\n R13: ff11001ff83e5000 R14: ffffffff9dba7c60 R15: 0000000000000c00\n memblock_double_array+0xff/0x310\n memblock_add_range+0x1fb/0x2f0\n memblock_reserve+0x4f/0xa0\n memblock_alloc_range_nid+0xac/0x130\n memblock_alloc_internal+0x53/0xc0\n memblock_alloc_try_nid+0x3d/0xa0\n swiotlb_init_remap+0x149/0x2f0\n mem_init+0xb/0xb0\n mm_core_init+0x8f/0x350\n start_kernel+0x17e/0x5d0\n x86_64_start_reservations+0x14/0x30\n x86_64_start_kernel+0x92/0xa0\n secondary_startup_64_no_verify+0x194/0x19b\n\nMitigate this by calling accept_memory() on the memory range returned\nbefore the slab is available.\n\nPrior to v6.12, the accept_memory() interface used a 'start' and 'end'\nparameter instead of 'start' and 'size', therefore the accept_memory()\ncall must be adjusted to specify 'start + size' for 'end' when applying\nto kernels prior to v6.12." |
