wifi: p54: validate RX frame length in p54_rx_eeprom_readback()

2026-07-06T12:11:07+00:00

p54_rx_eeprom_readback() copies the requested EEPROM slice out of a device-supplied readback frame without checking that the skb actually holds that many bytes. Commit da1b9a55ff11 ("wifi: p54: prevent buffer-overflow in p54_rx_eeprom_readback()") closed the destination overflow by copying a fixed priv->eeprom_slice_size (and rejecting a mismatched advertised len), but the source side is still unbounded: nothing verifies the frame is long enough to supply that many bytes. A malicious USB device can send a short frame whose advertised len matches priv->eeprom_slice_size while the payload is truncated. The equality check passes and memcpy() reads past the end of the skb, leaking adjacent heap: BUG: KASAN: slab-out-of-bounds in p54_rx (drivers/net/wireless/intersil/p54/txrx.c:507) Read of size 1016 at addr ffff88800f077114 by task swapper/0/0 Call Trace: ... __asan_memcpy (mm/kasan/shadow.c:105) p54_rx (drivers/net/wireless/intersil/p54/txrx.c:507) p54u_rx_cb (drivers/net/wireless/intersil/p54/p54usb.c:163) __usb_hcd_giveback_urb (drivers/usb/core/hcd.c:1657) dummy_timer (drivers/usb/gadget/udc/dummy_hcd.c:2005) ...

Replace by more specific (c files)

Replace the #include of by the more specific where applicable. For most cases the include can be dropped completely, only a few drivers need one or two headers added.

p54spi: convert to devicetree

2026-05-20T10:05:04+00:00

The Prism54 SPI driver hardcodes GPIO numbers and expects users to pass them as module parameters, apparently a relic from its life as a staging driver. This works because there is only one user, the Nokia N8x0 tablet. Convert this to the gpio descriptor interface and DT based probing to improve this and simplify the code at the same time.

Convert more 'alloc_obj' cases to default GFP_KERNEL arguments

2026-02-22T04:03:00+00:00

This converts some of the visually simpler cases that have been split over multiple lines. I only did the ones that are easy to verify the resulting diff by having just that final GFP_KERNEL argument on the next line. Somebody should probably do a proper coccinelle script for this, but for me the trivial script actually resulted in an assertion failure in the middle of the script. I probably had made it a bit _too_ trivial. So after fighting that far a while I decided to just do some of the syntactically simpler cases with variations of the previous 'sed' scripts. The more syntactically complex multi-line cases would mostly really want whitespace cleanup anyway. Signed-off-by: Linus Torvalds

treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook
