Vulnerability from fkie_nvd - Published: 2025-01-15 13:15 - Updated: 2026-08-04 11:22

Severity

7.6 (High) - CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Summary

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fix mbss changed flags corruption on 32 bit systems On 32-bit systems, the size of an unsigned long is 4 bytes, while a u64 is 8 bytes. Therefore, when using or_each_set_bit(bit, &bits, sizeof(changed) * BITS_PER_BYTE), the code is incorrectly searching for a bit in a 32-bit variable that is expected to be 64 bits in size, leading to incorrect bit finding. Solution: Ensure that the size of the bits variable is correctly adjusted for each architecture. Call Trace: ? show_regs+0x54/0x58 ? __warn+0x6b/0xd4 ? ieee80211_link_info_change_notify+0xcc/0xd4 [mac80211] ? report_bug+0x113/0x150 ? exc_overflow+0x30/0x30 ? handle_bug+0x27/0x44 ? exc_invalid_op+0x18/0x50 ? handle_exception+0xf6/0xf6 ? exc_overflow+0x30/0x30 ? ieee80211_link_info_change_notify+0xcc/0xd4 [mac80211] ? exc_overflow+0x30/0x30 ? ieee80211_link_info_change_notify+0xcc/0xd4 [mac80211] ? ieee80211_mesh_work+0xff/0x260 [mac80211] ? cfg80211_wiphy_work+0x72/0x98 [cfg80211] ? process_one_work+0xf1/0x1fc ? worker_thread+0x2c0/0x3b4 ? kthread+0xc7/0xf0 ? mod_delayed_work_on+0x4c/0x4c ? kthread_complete_and_exit+0x14/0x14 ? ret_from_fork+0x24/0x38 ? kthread_complete_and_exit+0x14/0x14 ? ret_from_fork_asm+0xf/0x14 ? entry_INT80_32+0xf0/0xf0 [restore no-op path for no changes]

WiFi frame injection is Adjacent, not Network.\nAC:L - The attacker reliably and repeatedly triggers the path by transmitting mesh beacons/probe responses or peering frames with a matching mesh ID, and the frame-parsing code (`ieee802_11_parse_elems`, `mesh_plink_fsm`) runs on the same stack region immediately beforehand, so the adjacent stack word read out-of-bounds is substantially attacker-influenced rather than beyond their control.\nPR:N - No authentication or association is required \u2014 on an open mesh (`IEEE80211_MESH_SEC_NONE`) an unauthenticated neighbour\u0027s beacon alone drives `mesh_neighbour_update()` and auto peer-link open, and mesh peering action frames are likewise processed before any credentials are verified.\nUI:N - A mesh node processes received beacons, probe responses and peering frames automatically as part of normal operation; no action by any local user or administrator is needed.\nS:U - The out-of-bounds stack read, the corrupted `mbss_changed` bitmap and the resulting bogus driver reconfiguration all occur within the kernel\u0027s own security authority, with no crossing into another security scope.\nC:L - `_find_next_bit()` reads 4 bytes of adjacent kernel stack past the 4-byte `bits` variable, disclosing leftover stack contents into the change bitmap; the read is strictly bounded to one machine word and is never copied to the attacker directly, though the leaked bits can influence externally observable driver/radio state (e.g. `BSS_CHANGED_TPE`).\nI:L - Garbage bits 32\u201363 are propagated into a u64 change mask and handed to the driver\u0027s `link_info_changed` callback, causing unintended link and hardware reconfiguration with flags that are invalid for a mesh vif; the `set_bit()` writes themselves stay within the 64-bit `mbss_changed` bitmap, so there is no arbitrary-write primitive.\nA:H - The corrupted flags reach `WARN_ON_ONCE(changed \u0026 BSS_CHANGED_VIF_CFG_FLAGS)` in `ieee80211_link_info_change_notify()` \u2014 a kernel splat that panics outright on the `panic_on_warn` configurations common in embedded/router deployments \u2014 and the same bogus flags drive drivers into unexpected reconfiguration paths, remotely and repeatedly triggerable without authentication."

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
