According to RCU usage rules, this is illegal. Reusing this\npointer can lead to unpredictable behavior, including accessing memory\nthat has been updated or causing use-after-free issues.\n\nThis possible bug was identified using a static analysis tool developed\nby myself, specifically designed to detect RCU-related issues.\n\nTo address this, the TSF value is now stored in a local variable\n`ies_tsf` before the RCU lock is released. The `param->tsf_lo` field is\nthen assigned using this local variable, ensuring that the TSF value is\nsafely accessed." } ], "metrics": [ { "cvssV3_1": { "version": "3.1", "vectorString":

802.11 beacon/probe-response frames that cause `cfg80211_update_known_bss()` to `kfree_rcu()` the old IE blob, and the gating P2P NoA attribute is supplied in those same frames, so the attacker must be within WiFi radio range of the victim.\nAC:L - The attacker controls both the gating condition (presence of the P2P NoA attribute in its beacons) and the free timing (flooding IE-changing beacons/probe responses), and can retry the race indefinitely across repeated association attempts, giving repeatable success on preemptible kernels.\nPR:N - No credentials on the target are needed — the connect that reaches the vulnerable parser is issued automatically by the supplicant during association/roaming, and even the local trigger `NL80211_CMD_CONNECT` requires only namespace-scoped CAP_NET_ADMIN (`GENL_UNS_ADMIN_PERM`), not real root.\nUI:N - Association and roaming attempts are performed automatically by wpa_supplicant against configured/rogue SSIDs; no victim action is required for the connect path to run.\nS:U - The stale read and its consequences are confined to the kernel's own security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - This is a use-after-free read of a freed slab object whose contents (freelist pointer or reallocated kernel heap data) are truncated into `param->tsf_lo` and programmed into the firmware's NoA/power-save schedule, leaking freed kernel memory into behavior the adjacent attacker can observe.\nI:L - There is no out-of-bounds or arbitrary write — the only store is into the correctly allocated `param` — but attacker-influenced freed-heap garbage corrupts the TSF/NoA join parameters handed to the device firmware, a bounded integrity impact on driver and firmware state.\nA:H - Dereferencing the freed `cfg80211_bss_ies` can fault and oops if the backing slab page has been returned to the page allocator (attacker can induce this by churning the BSS list), and it triggers KASAN/hardened-allocator panics." } ] } ], "affected": [ { "product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": [
