"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nwifi: p54: validate RX frame length in p54_rx_eeprom_readback()\n\np54_rx_eeprom_readback() copies the requested EEPROM slice out of a\ndevice-supplied readback frame without checking that the skb actually holds\nthat many bytes. Commit da1b9a55ff11 (\"wifi: p54: prevent buffer-overflow in\np54_rx_eeprom_readback()\") closed the destination overflow by copying a\nfixed priv->eeprom_slice_size (and rejecting a mismatched advertised len),\nbut the source side is still unbounded: nothing verifies the frame is long\nenough to supply that many bytes.\n\nA malicious USB device can send a short frame whose advertised len matches\npriv->eeprom_slice_size while the payload is truncated. The equality check\npasses and memcpy() reads past the end of the skb, leaking adjacent heap:\n\n BUG: KASAN: slab-out-of-bounds in p54_rx (drivers/net/wireless/intersil/p54/txrx.c:507)\n Read of size 1016 at addr ffff88800f077114 by task swapper/0/0\n Call Trace:\n <IRQ>\n ...\n __asan_memcpy (mm/kasan/shadow.c:105)\n p54_rx (drivers/net/wireless/intersil/p54/txrx.c:507)\n p54u_rx_cb (drivers/net/wireless/intersil/p54/p54usb.c:163)\n __usb_hcd_giveback_urb (drivers/usb/core/hcd.c:1657)\n dummy_timer (drivers/usb/gadget/udc/dummy_hcd.c:2005)\n ...\n </IRQ>\n\n The buggy address belongs to the object at ffff88800f0770c0\n which belongs to the cache skbuff_small_head of size 704\n The buggy address is located 84 bytes inside of\n allocated 704-byte region [ffff88800f0770c0, ffff88800f077380)\n\nCheck that the slice fits in the skb before copying."
