| In the Linux kernel, the following vulnerability has been resolved:
netfilter: ipset: Fix overflow before widen in the bitmap_ip_create() function.
When first_ip is 0, last_ip is 0xFFFFFFFF, and netmask is 31, the value of
an arithmetic expression 2 << (netmask - mask_bits - 1) is subject
to overflow due to a failure casting operands to a larger data type
before performing the arithmetic.
Note that it's harmless since the value will be checked at the next step.
Found by InfoTeCS on behalf of Linux Verification Center
(linuxtesting.org) with SVACE. |

The above warning triggered because the current imc-pmu code uses mutex
lock in interrupt disabled sections. The function mutex_lock()
internally calls __might_resched(), which will check if IRQs are
disabled and in case IRQs are disabled, it will trigger the warning.
Fix the issue by changing the mutex lock to spinlock.

| In the Linux kernel, the following vulnerability has been resolved:
ksmbd: prevent connection release during oplock break notification
ksmbd_work could be freed when after connection release.
Increment r_count of ksmbd_conn to indicate that requests

| In the Linux kernel, the following vulnerability has been resolved:
netmem: prevent TX of unreadable skbs
Currently on stable trees we have support for netmem/devmem RX but not
TX. It is not safe to forward/redirect an RX unreadable netmem packet
into the device's TX path, as the device may call dma-mapping APIs on
dma addrs that should not be passed to it.
Fix this by preventing the xmit of unreadable skbs.
Tested by configuring tc redirect:
sudo tc qdisc add dev eth1 ingress
sudo tc filter add dev eth1 ingress protocol ip prio 1 flower ip_proto \
tcp src_ip 192.168.1.12 action mirred egress redirect dev eth1
Before, I see unreadable skbs in the driver's TX path passed to dma
mapping APIs.
After, I don't see unreadable skbs in the driver's TX path passed to dma
mapping APIs. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ethtool: netlink: Allow NULL nlattrs when getting a phy_device
ethnl_req_get_phydev() is used to lookup a phy_device, in the case an
ethtool netlink command targets a specific phydev within a netdev's
topology.
It takes as a parameter a const struct nlattr *header that's used for
error handling :
if (!phydev) {
NL_SET_ERR_MSG_ATTR(extack, header,
"no phy matching phyindex");
return ERR_PTR(-ENODEV);
}
In the notify path after a ->set operation however, there's no request
attributes available.
The typical callsite for the above function looks like:
phydev = ethnl_req_get_phydev(req_base, tb[ETHTOOL_A_XXX_HEADER],
info->extack);
So, when tb is NULL (such as in the ethnl notify path), we have a nice
crash.
It turns out that there's only the PLCA command that is in that case, as
the other phydev-specific commands don't have a notification.
This commit fixes the crash by passing the cmd index and the nlattr
array separately, allowing NULL-checking it directly inside the helper. |
| In the Linux kernel, the following vulnerability has been resolved:
mm: memory-failure: update ttu flag inside unmap_poisoned_folio
Patch series "mm: memory_failure: unmap poisoned folio during migrate
properly", v3.
Fix two bugs during folio migration if the folio is poisoned.
This patch (of 3):
Commit 6da6b1d4a7df ("mm/hwpoison: convert TTU_IGNORE_HWPOISON to
TTU_HWPOISON") introduce TTU_HWPOISON to replace TTU_IGNORE_HWPOISON in
order to stop send SIGBUS signal when accessing an error page after a
memory error on a clean folio. However during page migration, anon folio
must be set with TTU_HWPOISON during unmap_*(). For pagecache we need
some policy just like the one in hwpoison_user_mappings to set this flag.
So move this policy from hwpoison_user_mappings to unmap_poisoned_folio to
handle this warning properly.
Warning will be produced during unamp poison folio with the following log:

| In the Linux kernel, the following vulnerability has been resolved:
wifi: iwlwifi: mvm: clean up ROC on failure
If the firmware fails to start the session protection, then we
do call iwl_mvm_roc_finished() here, but that won't do anything
at all because IWL_MVM_STATUS_ROC_P2P_RUNNING was never set.
Set IWL_MVM_STATUS_ROC_P2P_RUNNING in the failure/stop path.
If it started successfully before, it's already set, so that
doesn't matter, and if it didn't start it needs to be set to
clean up.
Not doing so will lead to a WARN_ON() later on a fresh remain-
on-channel, since the link is already active when activated as
it was never deactivated. |

| In the Linux kernel, the following vulnerability has been resolved:
drm/fbdev-dma: Add shadow buffering for deferred I/O
DMA areas are not necessarily backed by struct page, so we cannot
rely on it for deferred I/O. Allocate a shadow buffer for drivers
that require deferred I/O and use it as framebuffer memory.
Fixes driver errors about being "Unable to handle kernel NULL pointer
dereference at virtual address" or "Unable to handle kernel paging
request at virtual address".
The patch splits drm_fbdev_dma_driver_fbdev_probe() in an initial
allocation, which creates the DMA-backed buffer object, and a tail
that sets up the fbdev data structures. There is a tail function for
direct memory mappings and a tail function for deferred I/O with
the shadow buffer.
It is no longer possible to use deferred I/O without shadow buffer.
It can be re-added if there exists a reliably test for usable struct
page in the allocated DMA-backed buffer object. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: btusb: mediatek: Add locks for usb_driver_claim_interface()
The documentation for usb_driver_claim_interface() says that "the
device lock" is needed when the function is called from places other
than probe(). This appears to be the lock for the USB interface
device. The Mediatek btusb code gets called via this path:
Workqueue: hci0 hci_power_on [bluetooth]
Call trace:
usb_driver_claim_interface
btusb_mtk_claim_iso_intf
btusb_mtk_setup
hci_dev_open_sync
hci_power_on
process_scheduled_works
worker_thread
kthread
With the above call trace the device lock hasn't been claimed. Claim
it.
Without this fix, we'd sometimes see the error "Failed to claim iso
interface". Sometimes we'd even see worse errors, like a NULL pointer
dereference (where `intf->dev.driver` was NULL) with a trace like:
Call trace:
usb_suspend_both
usb_runtime_suspend
__rpm_callback
rpm_suspend
pm_runtime_work
process_scheduled_works
Both errors appear to be fixed with the proper locking. |
