| In the Linux kernel, the following vulnerability has been resolved:
crypto: ecc - Fix carry overflow in vli multiplication
The carry flag calculation fails when r01.m_high is saturated
(0xFFFFFFFFFFFFFFFF) and addition of lower bits overflows.
The condition (r01.m_high < product.m_high) doesn't handle the case
where r01.m_high == product.m_high and an additional carry exists
from lower-bit overflow.
When commit 3c4b23901a0c ("crypto: ecdh - Add ECDH software support")
introduced crypto/ecc.c, it split the muladd() function in the
micro-ecc library into separate mul_64_64() and add_128_128() helpers.
It seems the check got lost in translation.
Add proper handling for this boundary by accounting for the carry
from the lower addition. |
| In the Linux kernel, the following vulnerability has been resolved:
nvmet-auth: validate reply message payload bounds against transfer length
nvmet_auth_reply() accesses the variable-length rval[] array using
attacker-controlled hl (hash length) and dhvlen (DH value length) fields
without verifying they fit within the allocated buffer of tl bytes.
A malicious NVMe-oF initiator can craft a DHCHAP_REPLY message with a
small transfer length but large hl/dhvlen values, causing out-of-bounds
heap reads when the target processes the DH public key (rval + 2*hl) or
performs the host response memcmp.
With DH authentication configured, the OOB pointer is passed directly to
sg_init_one() and read by crypto_kpp_compute_shared_secret(), reaching
up to 526 bytes past the buffer. This is exploitable pre-authentication.
Add bounds validation ensuring sizeof(*data) + 2*hl + dhvlen <= tl before
any access to the variable-length fields.

| In the Linux kernel, the following vulnerability has been resolved:
block: skip sync_blockdev() on surprise removal in bdev_mark_dead()
bdev_mark_dead()'s @surprise == true means the device is already gone.
The filesystem callback fs_bdev_mark_dead() honours this and skips
sync_filesystem(), but the bare block device path (no ->mark_dead op)
lost its !surprise guard when the holder ->mark_dead callback was wired
up (see Fixes), and now calls sync_blockdev() unconditionally, which can
hang forever waiting on writeback that can no longer complete.
syzkaller hit this via nvme_reset_work()'s "I/O queues lost" path:
nvme_mark_namespaces_dead() -> blk_mark_disk_dead() ->
bdev_mark_dead(bdev, true) -> sync_blockdev() blocks in
folio_wait_writeback(), wedging the reset worker and every task waiting
on it.
Skip the sync on surprise removal, matching fs_bdev_mark_dead();
invalidate_bdev() still runs. Orderly removal (surprise == false) is
unchanged.

| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_fs: Initialize epfile->in early to fix endpoint direction checks
When parsing endpoint descriptors, ffs_data_got_descs() generates the
eps_addrmap which contains the endpoint direction. However, epfile->in
was previously only populated in ffs_func_eps_enable() which executes
upon USB host connection. As a result, early userspace ioctls like
FUNCTIONFS_DMABUF_ATTACH that run before the host connects would see
epfile->in as 0, leading to incorrect DMA directions.
By moving the initialization to ffs_epfiles_create(), epfile->in is
accurate before userspace opens the endpoint files. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: typec: ucsi: ccg: Fix use-after-free of ucsi on remove
The threaded IRQ handler ccg_irq_handler() calls ucsi_notify_common(),
which on a connector-change event calls ucsi_connector_change() and
schedules connector work. In ucsi_ccg_remove(), ucsi_destroy() frees
uc->ucsi (kfree) before free_irq() is called, so a handler invocation
already in flight may access the freed object after ucsi_destroy().
CPU 0 (remove) | CPU 1 (threaded IRQ)
ucsi_destroy(uc->ucsi) | ccg_irq_handler()
kfree(ucsi) // FREE | ucsi_notify_common(uc->ucsi) // USE
Move free_irq() before ucsi_destroy() in the remove path. It is kept
after ucsi_unregister(): ucsi_unregister() cancels connector work whose
handler issues GET_CONNECTOR_STATUS through ucsi_send_command_common(),
which waits for a completion that is signalled from the IRQ handler, so
the IRQ must stay active until that work has been cancelled.
The probe error path already orders free_irq() before ucsi_destroy().
This bug was found by static analysis. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: ulpi: fix memory leak on registration failure
The allocated device name is never freed on early ULPI device
registration failures.
Fix this by initialising the device structure earlier and releasing the
initial reference whenever registration fails. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: digi_acceleport: fix write buffer corruption
The digi_write_inb_command() is supposed to wait for the write urb to
become available or return an error, but instead it updates the transfer
buffer and tries to resubmit the urb on timeout.
To make things worse, for commands like break control where no timeout
is used, the driver would corrupt the urb immediately due to a broken
jiffies comparison (on 32-bit machines this takes five minutes of uptime
to trigger due to INITIAL_JIFFIES).
Fix this by adding the missing return on timeout and waiting
indefinitely when no timeout has been specified as intended.
This issue was (sort of) flagged by Sashiko when reviewing an unrelated
change to the driver. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: misc: uss720: unregister parport on probe failure
uss720_probe() registers a parport before reading the 1284 register used
to detect unsupported Belkin F5U002 adapters. If get_1284_register()
fails, the error path drops the driver private data and the USB device
reference, but leaves the parport device registered.
Leaving the port registered is more than a private allocation leak:
parport_register_port() has already reserved a parport number and
registered the parport bus device, while pp->private_data still points at
the private data that the common error path is about to release.
Undo the pre-announce registration in the get_1284_register() failure
branch before jumping to the common private-data cleanup path. Clear
priv->pp first, matching the disconnect path and avoiding a stale pointer
in the private data.
This issue was identified during our ongoing static-analysis research while
reviewing kernel code. |

| In the Linux kernel, the following vulnerability has been resolved:
USB: iowarrior: fix use-after-free on disconnect
Submitted write URBs are not stopped on close() and therefore need to be
stopped unconditionally on disconnect() to avoid use-after-free in the
completion handler. |
| In the Linux kernel, the following vulnerability has been resolved:
net: usb: kalmia: bound RX frame length in kalmia_rx_fixup()
kalmia_rx_fixup() computes usb_packet_length = skb->len - (2 *
KALMIA_HEADER_LENGTH) as a u16, guarded only by a pre-loop check that
skb->len is at least KALMIA_HEADER_LENGTH, which is 6. A device can
deliver a short bulk-IN frame with skb->len in the 6 to 11 range, or
leave a short trailing remainder on a later loop iteration. Either case
underflows usb_packet_length to about 65530.
That bypasses the usb_packet_length < ether_packet_length truncation path.
The device-supplied ether_packet_length, a le16 up to 65535 read from
header_start[2], then drives a memcmp() and the following skb_trim() and
skb_pull() past the end of the rx buffer. The rx buffer is hard_mtu * 10,
which is 14000 bytes. That is an out of bounds read.
Require both the start and end framing headers to be present before
subtracting them, on every loop iteration. |
