  "details": "In the Linux kernel, the following vulnerability has been resolved:  wifi: mac80211: avoid out-of-bounds read for empty PREQ elements  ieee80211_mesh_preq_size_ok() derives the location of the PREQ bottom fields before checking whether the element contains even the fixed header. ieee80211_mesh_hwmp_preq_get_bottom() reads the flags byte to account for the optional Address Extension field. Consequently, an empty PREQ element causes a one-byte read beyond its declared payload.  Move the helper call after both size checks, so the bottom fields are only accessed when they are present.",
