      "summary": "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]",
