Official description

In the Linux kernel, the following vulnerability has been resolved: ACPI: APEI: Fix integer overflow in ghes_estatus_pool_init() Change num_ghes from int to unsigned int, preventing an overflow and causing subsequent vmalloc() to fail. The overflow happens in ghes_estatus_pool_init() when calculating len during execution of the statement below as both multiplication operands here are signed int: len += (num_ghes * GHES_ESOURCE_PREALLOC_MAX_SIZE); The following call trace is observed because of this bug: [ 9.317108] swapper/0: vmalloc error: size 18446744071562596352, exceeds total pages, mode:0xcc0(GFP_KERNEL), nodemask=(null),cpuset=/,mems_allowed=0-1 [ 9.317131] Call Trace: [ 9.317134] <TASK> [ 9.317137] dump_stack_lvl+0x49/0x5f [ 9.317145] dump_stack+0x10/0x12 [ 9.317146] warn_alloc.cold+0x7b/0xdf [ 9.317150] ? __device_attach+0x16a/0x1b0 [ 9.317155] __vmalloc_node_range+0x702/0x740 [ 9.317160] ? device_add+0x17f/0x920 [ 9.317164] ? dev_set_name+0x53/0x70 [ 9.317166] ? platform_device_add+0xf9/0x240 [ 9.317168] __vmalloc_node+0x49/0x50 [ 9.317170] ? ghes_estatus_pool_init+0x43/0xa0 [ 9.317176] vmalloc+0x21/0x30 [ 9.317177] ghes_estatus_pool_init+0x43/0xa0 [ 9.317179] acpi_hest_init+0x129/0x19c [ 9.317185] acpi_init+0x434/0x4a4 [ 9.317188] ? acpi_sleep_proc_init+0x2a/0x2a [ 9.317190] do_one_initcall+0x48/0x200 [ 9.317195] kernel_init_freeable+0x221/0x284 [ 9.317200] ? rest_init+0xe0/0xe0 [ 9.317204] kernel_init+0x1a/0x130 [ 9.317205] ret_from_fork+0x22/0x30 [ 9.317208] </TASK> [ rjw: Subject and changelog edits ]
