{"id":"CVE-2023-53395","summary":"ACPICA: Add AML_NO_OPERAND_RESOLVE flag to Timer","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nACPICA: Add AML_NO_OPERAND_RESOLVE flag to Timer\n\nACPICA commit 90310989a0790032f5a0140741ff09b545af4bc5\n\nAccording to the ACPI specification 19.6.134, no argument is required to be passed for ASL Timer instruction. For taking care of no argument, AML_NO_OPERAND_RESOLVE flag is added to ASL Timer instruction opcode.\n\nWhen ASL timer instruction interpreted by ACPI interpreter, getting error. After adding AML_NO_OPERAND_RESOLVE flag to ASL Timer instruction opcode, issue is not observed.\n\n=============================================================\nUBSAN: array-index-out-of-bounds in acpica/dswexec.c:401:12 index -1 is out of range for type 'union acpi_operand_object *[9]'\nCPU: 37 PID: 1678 Comm: cat Not tainted\n6.0.0-dev-th500-6.0.y-1+bcf8c46459e407-generic-64k\nHW name: NVIDIA BIOS v1.1.1-d7acbfc-dirty 12/19/2022 Call trace:\n dump_backtrace+0xe0/0x130\n show_stack+0x20/0x60\n dump_stack_lvl+0x68/0x84\n dump_stack+0x18/0x34\n ubsan_epilogue+0x10/0x50\n __ubsan_handle_out_of_bounds+0x80/0x90\n acpi_ds_exec_end_op+0x1bc/0x6d8\n acpi_ps_parse_loop+0x57c/0x618\n acpi_ps_parse_aml+0x1e0/0x4b4\n acpi_ps_execute_method+0x24c/0x2b8\n acpi_ns_evaluate+0x3a8/0x4bc\n acpi_evaluate_object+0x15c/0x37c\n acpi_evaluate_integer+0x54/0x15c\n show_power+0x8c/0x12c [acpi_power_meter]","modified":"2026-04-02T09:44:07.448806Z","published":"2025-09-18T13:33:36.624Z","related":["SUSE-SU-2025:03600-1","SUSE-SU-2025:03614-1","SUSE-SU-2025:03615-1","SUSE-SU-2025:03628-1","SUSE-SU-2025:03634-1","SUSE-SU-2025:20851-1","SUSE-SU-2025:20861-1","SUSE-SU-2025:20870-1","SUSE-SU-2025:20898-1","SUSE-SU-2025:3716-1","SUSE-SU-2025:3751-1","SUSE-SU-2025:3761-1","SUSE-SU-2025:4057-1","SUSE-SU-2025:4132-1","SUSE-SU-2025:4135-1","SUSE-SU-2025:4141-1","SUSE-SU-2025:4188-1","SUSE-SU-2025:4315-1"],"database_specific":{"cna_assigner":"Linux","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53395.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/23c67fa615c52712bfa02a6dfadbd4656c87c066"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2f2a5905303ae230b5159fcd8cdcd5b3e7ad5e2d"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3a21ffdbc825e0919db9da0e27ee5ff2cc8a863e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/3bf4463e40a17a23f2f261dfd7fe23129bdd04a4"},{"type":"WEB","url":"https://git.kernel.org/stable/c/430787056dd3c591eb553d5c3b2717efcf307d4e"},{"type":"WEB","url":"https://git.kernel.org/stable/c/625c12dc04a607b79f180ef3ee5a12bf2e3324c0"},{"type":"WEB","url":"https://git.kernel.org/stable/c/b102113469487b460e9e77fe9e00d49c50fe8c86"},{"type":"WEB","url":"https://git.kernel.org/stable/c/e1f686930ee4b059c7baa3c3904b2401829f2589"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/53xxx/CVE-2023-53395.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-53395"},{"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":"1da177e4c3f41524e886b7f1b8a0c1fc7321cac2"},{"fixed":"2f2a5905303ae230b5159fcd8cdcd5b3e7ad5e2d"},{"fixed":"23c67fa615c52712bfa02a6dfadbd4656c87c066"},{"fixed":"3bf4463e40a17a23f2f261dfd7fe23129bdd04a4"},{"fixed":"625c12dc04a607b79f180ef3ee5a12bf2e3324c0"},{"fixed":"430787056dd3c591eb553d5c3b2717efcf307d4e"},{"fixed":"e1f686930ee4b059c7baa3c3904b2401829f2589"},{"fixed":"b102113469487b460e9e77fe9e00d49c50fe8c86"},{"fixed":"3a21ffdbc825e0919db9da0e27ee5ff2cc8a863e"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-53395.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
