The flow slot can then be reused and memset while still on the list, corrupting twt_list, and station removal leaves a dangling entry behind that mt7915_mac_twt_sched_list_add() later walks. The Linux kernel CVE team has assigned CVE-2026-90357 to this issue.

Affected files ============== The file(s) affected by this issue are: drivers/net/wireless/mediatek/mt76/mt7915/mac.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/c09d1b15ed2dc49060303b16a296b7b8b7794cbe https://git.kernel.org/stable/c/1bd5c4ed2b9045faf83315c54cd37a9b7c71b5c7 https://git.kernel.org/stable/c/cabe239e95b4eebf5b6c3654087b66ff9425bc7b https://git.kernel.org/stable/c/6bce0f1280c94af8314f895f404629da09f0788c https://git.kernel.org/stable/c/beaa42b875965dbc3e80e46970e0bfa60a94c2db https://git.kernel.org/stable/c/16a04441eab0dcd4d7126a6f66b370adbf28f96d
