| In the Linux kernel, the following vulnerability has been resolved:
auxdisplay: line-display: fix NULL dereference in linedisp_release
linedisp_release() currently retrieves the enclosing struct linedisp via
to_linedisp(). That lookup depends on the attachment list, but the
attachment may already have been removed before put_device() invokes the
release callback. This can happen in linedisp_unregister(), and can also
be reached from some linedisp_register() error paths.
In that case, to_linedisp() returns NULL and linedisp_release()
dereferences it while freeing the display resources.
The struct device released here is the embedded linedisp->dev used by
linedisp_register(), so retrieve the enclosing object directly with
container_of() instead. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: cdns3: gadget: fix state inconsistency on gadget init failure
When cdns3_gadget_start() fails, the DRD hardware is left in gadget mode
while software state remains INACTIVE, creating hardware/software state
inconsistency.
When switching to host mode via sysfs:
echo host > /sys/class/usb_role/13180000.usb-role-switch/role
The role state is not set to CDNS_ROLE_STATE_ACTIVE due to the error,
so cdns_role_stop() skips cleanup because state is still INACTIVE.
This violates the DRD controller design specification (Figure22),
which requires returning to idle state before switching roles.
This leads to a synchronous external abort in xhci_gen_setup() when
setting up the host controller:
[ 516.440698] configfs-gadget 13180000.usb: failed to start g1: -19

Fix by calling cdns_drd_gadget_off() in the error path to properly
clean up the DRD gadget state. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ti: icssg-prueth: fix missing data copy and wrong recycle in ZC RX dispatch
emac_dispatch_skb_zc() allocates a new skb via napi_alloc_skb() but
never copies the packet data from the XDP buffer into it. The skb is
passed up the stack containing uninitialized heap memory instead of
the actual received packet, leaking kernel heap contents to userspace.
Copy the received packet data from the XDP buffer into the skb using
skb_copy_to_linear_data().
Additionally, remove the skb_mark_for_recycle() call since the skb is
backed by the NAPI page frag allocator, not page_pool. Marking a
non-page_pool skb for recycle causes the free path to return pages to
a page_pool that does not own them, corrupting page_pool state.
The non-ZC path (emac_rx_packet) does not have these issues because it
uses napi_build_skb() to wrap the existing page_pool page directly,
requiring no copy, and correctly marks for recycle since the page comes
from page_pool_dev_alloc_pages(). |
| In the Linux kernel, the following vulnerability has been resolved:
net: use skb_header_pointer() for TCPv4 GSO frag_off check
Syzbot reported a KMSAN uninit-value warning in gso_features_check()
called from netif_skb_features() [1].
gso_features_check() reads iph->frag_off to decide whether to clear
mangleid_features. Accessing the IPv4 header via ip_hdr()/inner_ip_hdr()
can rely on skb header offsets that are not always safe for direct
dereference on packets injected from PF_PACKET paths.
Use skb_header_pointer() for the TCPv4 frag_off check so the header read
is robust whether data is already linear or needs copying.

| In the Linux kernel, the following vulnerability has been resolved:
mptcp: fix soft lockup in mptcp_recvmsg()
syzbot reported a soft lockup in mptcp_recvmsg() [0].
When receiving data with MSG_PEEK | MSG_WAITALL flags, the skb is not
removed from the sk_receive_queue. This causes sk_wait_data() to always
find available data and never perform actual waiting, leading to a soft
lockup.
Fix this by adding a 'last' parameter to track the last peeked skb.
This allows sk_wait_data() to make informed waiting decisions and prevent
infinite loops when MSG_PEEK is used.

| In the Linux kernel, the following vulnerability has been resolved:
usb: dwc2: gadget: Fix spin_lock/unlock mismatch in dwc2_hsotg_udc_stop()
dwc2_gadget_exit_clock_gating() internally calls call_gadget() macro,
which expects hsotg->lock to be held since it does spin_unlock/spin_lock
around the gadget driver callback invocation.
However, dwc2_hsotg_udc_stop() calls dwc2_gadget_exit_clock_gating()
without holding the lock. This leads to:
- spin_unlock on a lock that is not held (undefined behavior)
- The lock remaining held after dwc2_gadget_exit_clock_gating() returns,
causing a deadlock when spin_lock_irqsave() is called later in the
same function.
Fix this by acquiring hsotg->lock before calling
dwc2_gadget_exit_clock_gating() and releasing it afterwards, which
satisfies the locking requirement of the call_gadget() macro. |
