{"id":"DEBIAN-CVE-2022-49885","details":"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]  \u003cTASK\u003e [    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]  \u003c/TASK\u003e  [ rjw: Subject and changelog edits ]","modified":"2026-09-01T16:05:33.716180215Z","published":"2025-05-01T15:16:13.480Z","upstream":["CVE-2022-49885"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2022-49885"}],"affected":[{"package":{"name":"linux","ecosystem":"Debian:12","purl":"pkg:deb/debian/linux?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.8-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49885.json"}},{"package":{"name":"linux","ecosystem":"Debian:13","purl":"pkg:deb/debian/linux?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.8-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49885.json"}},{"package":{"name":"linux","ecosystem":"Debian:14","purl":"pkg:deb/debian/linux?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.0.8-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2022-49885.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
