An individual agreement can therefore reach ieee80211_s1g_rx_twt_setup() with twt->length too short for the full struct ieee80211_twt_params. The individual path passes twt to drv_add_twt_setup(). Both the tracepoint and the driver callback consume the complete parameters block, not merely req_type. Do not pass a short individual agreement to the driver. Broadcast agreements remain unchanged because they are rejected locally after accessing only req_type. [edit commit message to not overclaim lack of validation nor understate driver impact] The Linux kernel CVE team has assigned CVE-2026-80722 to this issue.

Affected files ============== The file(s) affected by this issue are: net/mac80211/s1g.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/92fcd0f30dc8e51f252589b082d46851d295cc1a https://git.kernel.org/stable/c/09d60d1f72e6598241490eb6c4e97245af895c09 https://git.kernel.org/stable/c/ff558072d199c1d641d1561da622e67f780514de https://git.kernel.org/stable/c/ade9e2f0f7f4d3089600ac2af8ef0b91746f923b https://git.kernel.org/stable/c/b558e07708d886acfcf4b0391ed7a8546e81d326 https://git.kernel.org/stable/c/47fb04c3826e1f90271d405523043d6708b9072a https://git.kernel.org/stable/c/0502d5077e419427d80f4d46ba95d0067f5fb916
