{"id":"CVE-2024-53055","summary":"wifi: iwlwifi: mvm: fix 6 GHz scan construction","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: iwlwifi: mvm: fix 6 GHz scan construction\n\nIf more than 255 colocated APs exist for the set of all\nAPs found during 2.4/5 GHz scanning, then the 6 GHz scan\nconstruction will loop forever since the loop variable\nhas type u8, which can never reach the number found when\nthat's bigger than 255, and is stored in a u32 variable.\nAlso move it into the loops to have a smaller scope.\n\nUsing a u32 there is fine, we limit the number of APs in\nthe scan list and each has a limit on the number of RNR\nentries due to the frame size. With a limit of 1000 scan\nresults, a frame size upper bound of 4096 (really it's\nmore like ~2300) and a TBTT entry size of at least 11,\nwe get an upper bound for the number of ~372k, well in\nthe bounds of a u32.","modified":"2026-04-02T12:22:40.743006Z","published":"2024-11-19T17:19:39.037Z","related":["SUSE-SU-2024:4314-1","SUSE-SU-2024:4316-1","SUSE-SU-2024:4318-1","SUSE-SU-2025:0201-1","SUSE-SU-2025:0201-2","SUSE-SU-2025:0229-1","SUSE-SU-2025:0289-1","SUSE-SU-2025:20163-1","SUSE-SU-2025:20164-1","SUSE-SU-2025:20246-1","SUSE-SU-2025:20247-1","USN-7276-1","USN-7277-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53055.json","cna_assigner":"Linux"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/2ac15e5a8f42fed5d90ed9e1197600913678c50f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/2ccd5badadab2d586e91546bf5af3deda07fef1f"},{"type":"WEB","url":"https://git.kernel.org/stable/c/7245012f0f496162dd95d888ed2ceb5a35170f1a"},{"type":"WEB","url":"https://git.kernel.org/stable/c/cde8a7eb5c6762264ff0f4433358e0a0d250c875"},{"type":"WEB","url":"https://git.kernel.org/stable/c/fc621e7a043de346c33bd7ae7e2e0c651d6152ef"},{"type":"WEB","url":"https://lists.debian.org/debian-lts-announce/2025/01/msg00001.html"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/53xxx/CVE-2024-53055.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-53055"},{"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":"eae94cf82d7456b57fa9fd55c1edb8a726dcc19c"},{"fixed":"2ac15e5a8f42fed5d90ed9e1197600913678c50f"},{"fixed":"cde8a7eb5c6762264ff0f4433358e0a0d250c875"},{"fixed":"fc621e7a043de346c33bd7ae7e2e0c651d6152ef"},{"fixed":"2ccd5badadab2d586e91546bf5af3deda07fef1f"},{"fixed":"7245012f0f496162dd95d888ed2ceb5a35170f1a"}]}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2024-53055.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:N/I:N/A:H"}]}
