| In the Linux kernel, the following vulnerability has been resolved:
Revert "riscv: Define TASK_SIZE_MAX for __access_ok()"
This reverts commit ad5643cf2f69 ("riscv: Define TASK_SIZE_MAX for
__access_ok()").
This commit changes TASK_SIZE_MAX to be LONG_MAX to optimize access_ok(),
because the previous TASK_SIZE_MAX (default to TASK_SIZE) requires some
computation.
The reasoning was that all user addresses are less than LONG_MAX, and all
kernel addresses are greater than LONG_MAX. Therefore access_ok() can
filter kernel addresses.
Addresses between TASK_SIZE and LONG_MAX are not valid user addresses, but
access_ok() let them pass. That was thought to be okay, because they are
not valid addresses at hardware level.
Unfortunately, one case is missed: get_user_pages_fast() happily accepts
addresses between TASK_SIZE and LONG_MAX. futex(), for instance, uses
get_user_pages_fast(). This causes the problem reported by Robert [1].
Therefore, revert this commit. TASK_SIZE_MAX is changed to the default:
TASK_SIZE.
This unfortunately reduces performance, because TASK_SIZE is more expensive
to compute compared to LONG_MAX. But correctness first, we can think about
optimization later, if required. |

KVM: x86/xen: Fix cleanup logic in emulation of Xen schedop poll hypercalls
kvm_xen_schedop_poll does a kmalloc_array() when a VM polls the host
for more than one event channel potr (nr_ports > 1).
After the kmalloc_array(), the error paths need to go through the
"out" label, but the call to kvm_read_guest_virt() does not.

which is supposed to be safe with how requests are allocated. But msg
ring requests alloc and free on their own, and hence must defer freeing
to a sane time.
Add an rcu_head and use kfree_rcu() in both spots where requests are
freed. Only the one in io_msg_tw_complete() is strictly required as it
has been visible on the other ring, but use it consistently in the other
spot as well.
This should not cause any other issues outside of KASAN rightfully
complaining about it. |

Dan has also reported following issues with the original patch
https://lore.kernel.org/all/33fe8fe7-719a-405a-9ed2-d9f816ce1d57@sabinyo.mountain/
Bug #1:
The zeroeth element of ctrl->pconfig[] is supposed to be unused. We
start counting at 1. However this code sets ctrl->pconfig[0].ch_mask = 128.
Bug #2:
There are SLIM_MAX_TX_PORTS (16) elements in tx_ch[] array but only
QCOM_SDW_MAX_PORTS + 1 (15) in the ctrl->pconfig[] array so it corrupts
memory like Yongqin Liu pointed out.
Bug 3:
Like Jie Gan pointed out, it erases all the tx information with the rx
information. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mac80211: reject VHT opmode for unsupported channel widths
VHT operating mode notifications are not defined for channel widths
below 20 MHz. In particular, 5 MHz and 10 MHz are not valid under the
VHT specification and must be rejected.
Without this check, malformed notifications using these widths may
reach ieee80211_chan_width_to_rx_bw(), leading to a WARN_ON due to
invalid input. This issue was reported by syzbot.
Reject these unsupported widths early in sta_link_apply_parameters()
when opmode_notif is used. The accepted set includes 20, 40, 80, 160,
and 80+80 MHz, which are valid for VHT. While 320 MHz is not defined
for VHT, it is allowed to avoid rejecting HE or EHT clients that may
still send a VHT opmode notification. |
| In the Linux kernel, the following vulnerability has been resolved:
x86/sev: Use TSC_FACTOR for Secure TSC frequency calculation
When using Secure TSC, the GUEST_TSC_FREQ MSR reports a frequency based on
the nominal P0 frequency, which deviates slightly (typically ~0.2%) from
the actual mean TSC frequency due to clocking parameters.
Over extended VM uptime, this discrepancy accumulates, causing clock skew
between the hypervisor and a SEV-SNP VM, leading to early timer interrupts as
perceived by the guest.
The guest kernel relies on the reported nominal frequency for TSC-based
timekeeping, while the actual frequency set during SNP_LAUNCH_START may
differ. This mismatch results in inaccurate time calculations, causing the
guest to perceive hrtimers as firing earlier than expected.
Utilize the TSC_FACTOR from the SEV firmware's secrets page (see "Secrets
Page Format" in the SNP Firmware ABI Specification) to calculate the mean
TSC frequency, ensuring accurate timekeeping and mitigating clock skew in
SEV-SNP VMs.
Use early_ioremap_encrypted() to map the secrets page as
ioremap_encrypted() uses kmalloc() which is not available during early TSC
initialization and causes a panic.

HID: nintendo: avoid bluetooth suspend/resume stalls
Ensure we don't stall or panic the kernel when using bluetooth-connected
controllers. This was reported as an issue on android devices using
kernel 6.6 due to the resume hook which had been added for usb joycons.
First, set a new state value to JOYCON_CTLR_STATE_SUSPENDED in a
newly-added nintendo_hid_suspend. This makes sure we will not stall out
the kernel waiting for input reports during led classdev suspend. The
stalls could happen if connectivity is unreliable or lost to the
controller prior to suspend.
Second, since we lose connectivity during suspend, do not try
joycon_init() for bluetooth controllers in the nintendo_hid_resume path.
Tested via multiple suspend/resume flows when using the controller both
in USB and bluetooth modes. |
| In the Linux kernel, the following vulnerability has been resolved:
wifi: mwifiex: discard erroneous disassoc frames on STA interface
When operating in concurrent STA/AP mode with host MLME enabled,
the firmware incorrectly sends disassociation frames to the STA
interface when clients disconnect from the AP interface.
This causes kernel warnings as the STA interface processes

Add validation in the STA receive path to verify that disassoc/deauth
frames originate from the connected AP. Frames that fail this check
are discarded early, preventing them from reaching the MLME layer and
triggering WARN_ON().
This filtering logic is similar with that used in the
ieee80211_rx_mgmt_disassoc() function in mac80211, which drops
disassoc frames that don't match the current BSSID
(!ether_addr_equal(mgmt->bssid, sdata->vif.cfg.ap_addr)), ensuring
only relevant frames are processed.

Bluetooth: btnxpuart: Resolve TX timeout error in power save stress test
This fixes the tx timeout issue seen while running a stress test on

Test procedure using bash script:

hcitool -i hci0 cmd 3f 23 02 00 00
while (true)
do
hciconfig hci0 leadv

hciconfig hci0 noleadv
sleep 2
done
Error log, after adding few more debug prints:
Bluetooth: btnxpuart_queue_skb(): 01 0A 20 01 00
Bluetooth: hci0: Set UART break: on, status=0
Bluetooth: hci0: btnxpuart_tx_wakeup() tx_work scheduled

Can't set advertise mode on hci0: Connection timed out (110)
Bluetooth: hci0: command 0x200a tx timeout
When the power save mechanism turns on UART break, and btnxpuart_tx_work()
is scheduled simultaneously, psdata->ps_state is read as PS_STATE_AWAKE,
which prevents the psdata->work from being scheduled, which is responsible
to turn OFF UART break.
This issue is fixed by adding a ps_lock mutex around UART break on/off as
well as around ps_state read/write.
btnxpuart_tx_wakeup() will now read updated ps_state value. If ps_state is
PS_STATE_SLEEP, it will first schedule psdata->work, and then it will
reschedule itself once UART break has been turned off and ps_state is
PS_STATE_AWAKE.
Tested above script for 50,000 iterations and TX timeout error was not
observed anymore. |

sh_size is set to that value. During module_memory_alloc() the size is

Fix the this by checking the value of 'screen_size' before memset_io(). |
| In the Linux kernel, the following vulnerability has been resolved:
sched/core: Do not requeue task on CPU excluded from cpus_mask
The following warning was triggered on a large machine early in boot on
a distribution kernel but the same problem should also affect mainline.
WARNING: CPU: 439 PID: 10 at ../kernel/workqueue.c:2231 process_one_work+0x4d/0x440

Commit c6e7bd7afaeb ("sched/core: Optimize ttwu() spinning on p->on_cpu")
optimises ttwu by queueing a task that is descheduling on the wakelist,
but does not check if the task descheduling is still allowed to run on that CPU.
In this warning, the problematic task is a workqueue rescue thread which
checks if the rescue is for a per-cpu workqueue and running on the wrong CPU.
While this is early in boot and it should be possible to create workers,
the rescue thread may still used if the MAYDAY_INITIAL_TIMEOUT is reached
or MAYDAY_INTERVAL and on a sufficiently large machine, the rescue
thread is being used frequently.
Tracing confirmed that the task should have migrated properly using the
stopper thread to handle the migration. However, a parallel wakeup from udev
running on another CPU that does not share CPU cache observes p->on_cpu and
uses task_cpu(p), queues the task on the old CPU and triggers the warning.
Check that the wakee task that is descheduling is still allowed to run
on its current CPU and if not, wait for the descheduling to complete
and select an allowed CPU. |
