{"id":"CVE-2024-57899","summary":"wifi: mac80211: fix mbss changed flags corruption on 32 bit systems","details":"In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: mac80211: fix mbss changed flags corruption on 32 bit systems\n\nOn 32-bit systems, the size of an unsigned long is 4 bytes,\nwhile a u64 is 8 bytes. Therefore, when using\nor_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE),\nthe code is incorrectly searching for a bit in a 32-bit\nvariable that is expected to be 64 bits in size,\nleading to incorrect bit finding.\n\nSolution: Ensure that the size of the bits variable is correctly\nadjusted for each architecture.\n\n Call Trace:\n  ? show_regs+0x54/0x58\n  ? __warn+0x6b/0xd4\n  ? ieee80211_link_info_change_notify+0xcc/0xd4 [mac80211]\n  ? report_bug+0x113/0x150\n  ? exc_overflow+0x30/0x30\n  ? handle_bug+0x27/0x44\n  ? exc_invalid_op+0x18/0x50\n  ? handle_exception+0xf6/0xf6\n  ? exc_overflow+0x30/0x30\n  ? ieee80211_link_info_change_notify+0xcc/0xd4 [mac80211]\n  ? exc_overflow+0x30/0x30\n  ? ieee80211_link_info_change_notify+0xcc/0xd4 [mac80211]\n  ? ieee80211_mesh_work+0xff/0x260 [mac80211]\n  ? cfg80211_wiphy_work+0x72/0x98 [cfg80211]\n  ? process_one_work+0xf1/0x1fc\n  ? worker_thread+0x2c0/0x3b4\n  ? kthread+0xc7/0xf0\n  ? mod_delayed_work_on+0x4c/0x4c\n  ? kthread_complete_and_exit+0x14/0x14\n  ? ret_from_fork+0x24/0x38\n  ? kthread_complete_and_exit+0x14/0x14\n  ? ret_from_fork_asm+0xf/0x14\n  ? entry_INT80_32+0xf0/0xf0\n\n[restore no-op path for no changes]","modified":"2026-04-16T00:01:39.782675396Z","published":"2025-01-15T13:05:50.701Z","related":["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/2024/57xxx/CVE-2024-57899.json"},"references":[{"type":"WEB","url":"https://git.kernel.org/stable/c/36b739637d7042843f9df57212ecee6ed6e0d4b2"},{"type":"WEB","url":"https://git.kernel.org/stable/c/49dba1ded8dd5a6a12748631403240b2ab245c34"},{"type":"WEB","url":"https://git.kernel.org/stable/c/86772872f9f5097cd03d0e1c6813238bd38c250b"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2024/57xxx/CVE-2024-57899.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-57899"},{"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":"15ddba5f43114c1fd9cd83676e04a9e1acf8e37f"},{"fixed":"86772872f9f5097cd03d0e1c6813238bd38c250b"},{"fixed":"36b739637d7042843f9df57212ecee6ed6e0d4b2"},{"fixed":"49dba1ded8dd5a6a12748631403240b2ab245c34"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2024-57899.json"}}],"schema_version":"1.7.5"}
