serial: qcom-geni: Fix blocked task
Revert commit 1afa70632c39 ("serial: qcom-geni: Enable PM runtime for
serial driver") and its dependent commit 86fa39dd6fb7 ("serial:
qcom-geni: Enable Serial on SA8255p Qualcomm platforms") because the
first one causes regression - hang task on Qualcomm RB1 board (QRB2210)
and unable to use serial at all during normal boot:

The issue was reported on 12th of August and was ignored by author of
commits introducing issue for two weeks. Only after complaining author
produced a fix which did not work, so if original commits cannot be
reliably fixed for 5 weeks, they obviously are buggy and need to be
dropped. |

drm/vmwgfx: Fix Use-after-free in validation
Nodes stored in the validation duplicates hashtable come from an arena
allocator that is cleared at the end of vmw_execbuf_process. All nodes
are expected to be cleared in vmw_validation_drop_ht but this node escaped
because its resource was destroyed prematurely. |
| In the Linux kernel, the following vulnerability has been resolved:
sparc: fix accurate exception reporting in copy_{from_to}_user for Niagara
The referenced commit introduced exception handlers on user-space memory
references in copy_from_user and copy_to_user. These handlers return from
the respective function and calculate the remaining bytes left to copy
using the current register contents. This commit fixes a couple of bad
calculations and a broken epilogue in the exception handlers. This will
prevent crashes and ensure correct return values of copy_from_user and
copy_to_user in the faulting case. The behaviour of memcpy stays unchanged. |

scsi: mpt3sas: Fix crash in transport port remove by using ioc_info()
During mpt3sas_transport_port_remove(), messages were logged with
dev_printk() against &mpt3sas_port->port->dev. At this point the SAS
transport device may already be partially unregistered or freed, leading
to a crash when accessing its struct device.
Using ioc_info(), which logs via the PCI device (ioc->pdev->dev),
guaranteed to remain valid until driver removal.

ext4: fix potential null deref in ext4_mb_init()
In ext4_mb_init(), ext4_mb_avg_fragment_size_destroy() may be called
when sbi->s_mb_avg_fragment_size remains uninitialized (e.g., if groupinfo
slab cache allocation fails). Since ext4_mb_avg_fragment_size_destroy()
lacks null pointer checking, this leads to a null pointer dereference.

ASoC: Intel: bytcr_rt5651: Fix invalid quirk input mapping
When an invalid value is passed via quirk option, currently
bytcr_rt5640 driver just ignores and leaves as is, which may lead to
unepxected results like OOB access.
This patch adds the sanity check and corrects the input mapping to the
certain default value if an invalid value is passed. |
| In the Linux kernel, the following vulnerability has been resolved:
sparc: fix accurate exception reporting in copy_{from_to}_user for UltraSPARC III
Anthony Yznaga tracked down that a BUG_ON in ext4 code with large folios
enabled resulted from copy_from_user() returning impossibly large values
greater than the size to be copied. This lead to __copy_from_iter()
returning impossible values instead of the actual number of bytes it was
able to copy.
The BUG_ON has been reported in
https://lore.kernel.org/r/b14f55642207e63e907965e209f6323a0df6dcee.camel@physik.fu-berlin.de
The referenced commit introduced exception handlers on user-space memory
references in copy_from_user and copy_to_user. These handlers return from
the respective function and calculate the remaining bytes left to copy
using the current register contents. The exception handlers expect that
%o2 has already been masked during the bulk copy loop, but the masking was
performed after that loop. This will fix the return value of copy_from_user
and copy_to_user in the faulting case. The behaviour of memcpy stays
unchanged. |

On PTL, GP counter 0 and 1 doesn't support auto counter reload feature,
thus it would trigger a #GP when trying to write 1 on bit 0 of CFG_B MSR
which requires to enable auto counter reload on GP counter 0.
The root cause of causing this issue is the check for auto counter
reload (ACR) counter mask from user space is incorrect in
intel_pmu_acr_late_setup() helper. It leads to an invalid ACR counter
mask from user space could be set into hw.config1 and then written into
CFG_B MSRs and trigger the MSR access warning.
e.g., User may create a perf event with ACR counter mask (config2=0xcb),
and there is only 1 event created, so "cpuc->n_events" is 1.
The correct check condition should be "i + idx >= cpuc->n_events"
instead of "i + idx > cpuc->n_events" (it looks a typo). Otherwise,
the counter mask would traverse twice and an invalid "cpuc->assign[1]"
bit (bit 0) is set into hw.config1 and cause MSR accessing error.
Besides, also check if the ACR counter mask corresponding events are
ACR events. If not, filter out these counter mask. If a event is not a
ACR event, it could be scheduled to an HW counter which doesn't support
ACR. It's invalid to add their counter index in ACR counter mask.
Furthermore, remove the WARN_ON_ONCE() since it's easily triggered as
user could set any invalid ACR counter mask and the warning message
could mislead users. |

In xdr_stream_decode_opaque_auth(), zero-length checksum.len causes

the value of checksum.len is not less than XDR_UNIT. |

wifi: ath12k: Fix peer lookup in ath12k_dp_mon_rx_deliver_msdu()
In ath12k_dp_mon_rx_deliver_msdu(), peer lookup fails because
rxcb->peer_id is not updated with a valid value. This is expected
in monitor mode, where RX frames bypass the regular RX
descriptor path that typically sets rxcb->peer_id.
As a result, the peer is NULL, and link_id and link_valid fields
in the RX status are not populated. This leads to a WARN_ON in
mac80211 when it receives data frame from an associated station
with invalid link_id.
Fix this potential issue by using ppduinfo->peer_id, which holds
the correct peer id for the received frame. This ensures that the
peer is correctly found and the associated link metadata is updated
accordingly.

ASoC: Intel: sof_sdw: Prevent jump to NULL add_sidecar callback
In create_sdw_dailink() check that sof_end->codec_info->add_sidecar

The original code assumed that if include_sidecar is true, the codec
on that link has an add_sidecar callback. But there could be other
codecs on the same link that do not have an add_sidecar callback. |

=> q->tag_set NULL pointer! (2)
=> q->tag_set = set; (3)
Fix this by checking if a valid table (map) exists before performing
request-based suspend and waiting for target I/O. When map is NULL,
skip these table-dependent suspend steps.
Even when map is NULL, no I/O can reach any target because there is
no table loaded; I/O submitted in this state will fail early in the
DM layer. Skipping the table-dependent suspend logic in this case
is safe and avoids NULL pointer dereferences. |

smc: Use __sk_dst_get() and dst_dev_rcu() in in smc_clc_prfx_set().
smc_clc_prfx_set() is called during connect() and not under RCU

Using sk_dst_get(sk)->dev could trigger UAF.
Let's use __sk_dst_get() and dev_dst_rcu() under rcu_read_lock()
after kernel_getsockname().
Note that the returned value of smc_clc_prfx_set() is not used

While at it, we change the 1st arg of smc_clc_prfx_set[46]_rcu()
not to touch dst there. |

The direct reason is f2fs_check_quota_consistency() may suffer null-ptr-deref
issue in strcmp().
The bug can be reproduced w/ below scripts:
mkfs.f2fs -f /dev/vdb
mount -t f2fs -o usrquota /dev/vdb /mnt/f2fs
quotacheck -uc /mnt/f2fs/
umount /mnt/f2fs

mount -t f2fs -o remount,usrjquota=,jqfmt=vfsold /dev/vdb /mnt/f2fs
umount /mnt/f2fs
So, before old_qname and new_qname comparison, we need to check whether

Address this issue by moving the streaming preparation and cleanup to
the vb2 .prepare_streaming() and .unprepare_streaming() operations. This
also simplifies the driver by allowing direct usage of the
v4l2_m2m_ioctl_streamon() and v4l2_m2m_ioctl_streamoff() helpers. |
| In the Linux kernel, the following vulnerability has been resolved:
firmware: arm_scmi: Account for failed debug initialization
When the SCMI debug subsystem fails to initialize, the related debug root
will be missing, and the underlying descriptor will be NULL.
Handle this fault condition in the SCMI debug helpers that maintain
metrics counters. |
| In the Linux kernel, the following vulnerability has been resolved:
idpf: cleanup remaining SKBs in PTP flows
When the driver requests Tx timestamp value, one of the first steps is
to clone SKB using skb_get. It increases the reference counter for that
SKB to prevent unexpected freeing by another component.
However, there may be a case where the index is requested, SKB is
assigned and never consumed by PTP flows - for example due to reset during
running PTP apps.
Add a check in release timestamping function to verify if the SKB
assigned to Tx timestamp latch was freed, and release remaining SKBs. |
