DEBIAN-CVE-2025-71234

In the Linux kernel, the following vulnerability has been resolved:  wifi: rtl8xxxu: fix slab-out-of-bounds in rtl8xxxustaadd  The driver does not set hw->stadatasize, which causes mac80211 to allocate insufficient space for driver private station data in _stainfoalloc(). When rtl8xxxustaadd() accesses members of struct rtl8xxxustainfo through sta->drvpriv, this results in a slab-out-of-bounds write.  KASAN report on RISC-V (VisionFive 2) with RTL8192EU adapter:    BUG: KASAN: slab-out-of-bounds in rtl8xxxustaadd+0x31c/0x346   Write of size 8 at addr ffffffd6d3e9ae88 by task kworker/u16:0/12  Set hw->stadatasize to sizeof(struct rtl8xxxustainfo) during probe, similar to how hw->vifdatasize is configured. This ensures mac80211 allocates sufficient space for the driver's per-station private data.  Tested on StarFive VisionFive 2 v1.2A board.
