In the Linux kernel, the following vulnerability has been resolved: memblock: Accept allocated memory before use in memblock_double_array() When increasing the array size in memblock_double_array() and the slab is not yet available, a call to memblock_find_in_range() is used to reserve/allocate memory. However, the range returned may not have been accepted, which can result in a crash when booting an SNP guest: RIP: 0010:memcpy_orig+0x68/0x130 Code: ...
