  "summary": "wifi: rtw88: fix OOB read from firmware RX descriptor exceeding DMA buffer",
  "details": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: rtw88: fix OOB read from firmware RX descriptor exceeding DMA buffer\n\nIn rtw_pci_rx_napi(), new_len is computed as the sum of pkt_len (14-bit\ndescriptor field, max 16383) and pkt_offset (drv_info_sz + shift, both\nfirmware-controlled). The result can exceed RTK_PCI_RX_BUF_SIZE (11478),\ncausing an out-of-bounds read from the pre-allocated DMA buffer when\nskb_put_data copies new_len bytes. The USB transport already validates\nthis (rtw_usb_rx_data_put checks against RTW_USB_MAX_RECVBUF_SZ); the\nPCIe path does not.\n\nAdd a check that new_len does not exceed the DMA buffer size.",
