{"id":"CVE-2024-56662","summary":"acpi: nfit: vmalloc-out-of-bounds Read in acpi_nfit_ctl","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nacpi: nfit: vmalloc-out-of-bounds Read in acpi_nfit_ctl\n\nFix an issue detected by syzbot with KASAN:\n\nBUG: KASAN: vmalloc-out-of-bounds in cmd_to_func drivers/acpi/nfit/\ncore.c:416 [inline]\nBUG: KASAN: vmalloc-out-of-bounds in acpi_nfit_ctl+0x20e8/0x24a0\ndrivers/acpi/nfit/core.c:459\n\nThe issue occurs in cmd_to_func when the call_pkg-\u003end_reserved2\narray is accessed without verifying that call_pkg points to a buffer\nthat is appropriately sized as a struct nd_cmd_pkg. This can lead\nto out-of-bounds access and undefined behavior if the buffer does not\nhave sufficient space.\n\nTo address this, a check was added in acpi_nfit_ctl() to ensure that\nbuf is not NULL and that buf_len is less than sizeof(*call_pkg)\nbefore accessing it. This ensures safe access to the members of\ncall_pkg, including the nd_reserved2 array.","modified":"2026-10-08T02:48:50.307696376Z","published":"2024-12-27T15:06:24.661Z","related":["ALSA-2025:20095","ALSA-2025:20518","SUSE-SU-2025:0289-1","SUSE-SU-2025:0428-1","SUSE-SU-2025:0499-1","SUSE-SU-2025:0557-1","SUSE-SU-2025:0565-1","SUSE-SU-2025:20165-1","SUSE-SU-2025:20166-1","SUSE-SU-2025:20248-1","SUSE-SU-2025:20249-1","USN-7379-2","USN-7380-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/56xxx/CVE-2024-56662.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/143f723e9eb4f0302ffb7adfdc7ef77eab3f68e0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/212846fafb753a48e869e2a342fc1e24048da771"},{"type":"WEB","url":"https://git.kernel.org/stable/c/265e98f72bac6c41a4492d3e30a8e5fd22fe0779"},{"type":"WEB","url":"https://git.kernel.org/stable/c/616aa5f3c86e0479bcbb81e41c08c43ff32af637"},{"type":"WEB","url":"https://git.kernel.org/stable/c/bbdb3307f609ec4dc9558770f464ede01fe52aed"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e08dc2dc3c3f7938df0e4476fe3e6fdec5583c1d"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00001.html"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/03/msg00002.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/56xxx/CVE-2024-56662.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-56662"},{"type":"PACKAGE","url":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"ebe9f6f19d80d8978d16078dff3d5bd93ad8d102"},{"fixed":"616aa5f3c86e0479bcbb81e41c08c43ff32af637"},{"fixed":"bbdb3307f609ec4dc9558770f464ede01fe52aed"},{"fixed":"143f723e9eb4f0302ffb7adfdc7ef77eab3f68e0"},{"fixed":"e08dc2dc3c3f7938df0e4476fe3e6fdec5583c1d"},{"fixed":"212846fafb753a48e869e2a342fc1e24048da771"},{"fixed":"265e98f72bac6c41a4492d3e30a8e5fd22fe0779"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.14.176"},{"fixed":"4.15"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"4.19.31"},{"fixed":"4.20"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"5.0.4"},{"fixed":"5.1"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"63108f2a408abea7ecab063efa0f398da4d0d14b"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"f5878c4f084dc6b1386dad03970bb61ad5e9dc4b"}]},{"type":"GIT","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","events":[{"introduced":"0c79794474895dbbc3c52225f7e9f73cfecbb7dd"}]}],"versions":["v4.14.336","v4.14.335","v4.14.334","v4.14.333","v4.14.332","v4.14.331","v4.14.330","v4.14.329","v4.14.328","v4.14.327","v4.14.326","v4.14.325","v4.14.324","v4.14.323","v4.14.322","v4.14.321","v4.14.320","v4.14.319","v4.14.318","v4.14.317","v4.14.316","v4.14.315","v4.14.314","v4.14.313","v4.14.312","v4.14.311","v4.14.310","v4.14.309","v4.14.308","v4.14.307","v4.14.306","v4.14.305","v4.14.304","v4.14.303","v4.14.302","v4.14.301","v4.14.300","v4.14.299","v4.14.298","v4.14.297","v4.14.296","v4.14.295","v4.14.294","v4.14.293","v4.14.292","v4.14.291","v4.14.290","v4.14.289","v4.14.288","v4.14.287","v4.14.286","v4.14.285","v4.14.284","v4.14.283","v4.14.282","v4.14.281","v4.14.280","v4.14.279","v4.14.278","v4.14.277","v4.14.276","v4.14.275","v4.14.274","v4.14.273","v4.14.272","v4.14.271","v4.14.270","v4.14.269","v4.14.268","v4.14.267","v4.14.266","v4.14.265","v4.14.264","v4.14.263","v4.14.262","v4.14.261","v4.14.260","v4.14.259","v4.14.258","v4.14.257","v4.14.256","v4.14.255","v4.14.254","v4.14.253","v4.14.252","v4.14.251","v4.14.250","v4.14.249","v4.14.248","v4.14.247","v4.14.246","v4.14.245","v4.14.244","v4.14.243","v4.14.242","v4.14.241","v4.14.240","v4.14.239","v4.14.238","v4.14.237","v4.14.236","v4.14.235","v4.14.234","v4.14.233","v4.14.232","v4.14.231","v4.14.230","v4.14.229","v4.14.228","v4.14.227","v4.14.226","v4.14.225","v4.14.224","v4.14.223","v4.14.222","v4.14.221","v4.14.220","v4.14.219","v4.14.218","v4.14.217","v4.14.216","v4.14.215","v4.14.214","v4.14.213","v4.14.212","v4.14.211","v4.14.210","v4.14.209","v4.14.208","v4.14.207","v4.14.206","v4.14.205","v4.14.204","v4.14.203","v4.14.202","v4.14.201","v4.14.200","v4.14.199","v4.14.198","v4.14.197","v4.14.196","v4.14.195","v4.14.194","v4.14.193","v4.14.192","v4.14.191","v4.14.190","v4.14.189","v4.14.188","v4.14.187","v4.14.186","v4.14.185","v4.14.184","v4.14.183","v4.14.182","v4.14.181","v4.14.180","v4.14.179","v4.14.178","v4.14.177","v4.14.176","v4.19.325","v4.19.324","v4.19.323","v4.19.322","v4.19.321","v4.19.320","v4.19.319",
