| In the Linux kernel, the following vulnerability has been resolved:
fuse: fix readahead reclaim deadlock
Commit e26ee4efbc79 ("fuse: allocate ff->release_args only if release is
needed") skips allocating ff->release_args if the server does not
implement open. However in doing so, fuse_prepare_release() now skips
grabbing the reference on the inode, which makes it possible for an
inode to be evicted from the dcache while there are inflight readahead
requests. This causes a deadlock if the server triggers reclaim while
servicing the readahead request and reclaim attempts to evict the inode
of the file being read ahead. Since the folio is locked during
readahead, when reclaim evicts the fuse inode and fuse_evict_inode()
attempts to remove all folios associated with the inode from the page
cache (truncate_inode_pages_range()), reclaim will block forever waiting
for the lock since readahead cannot relinquish the lock because it is
itself blocked in reclaim:

Fix this deadlock by allocating ff->release_args and grabbing the
reference on the inode when preparing the file for release even if the
server does not implement open. The inode reference will be dropped when
the last reference on the fuse file is dropped (see fuse_file_put() ->
fuse_release_end()). |

blk-throttle: prevent overflow while calculating wait time
There is a problem found by code review in tg_with_in_bps_limit() that
'bps_limit * jiffy_elapsed_rnd' might overflow. Fix the problem by
calling mul_u64_u64_div_u64() instead. |

PM / devfreq: hisi: Fix potential UAF in OPP handling
Ensure all required data is acquired before calling dev_pm_opp_put(opp)
to maintain correct resource acquisition and release order. |

KVM: arm64: Fix debug checking for np-guests using huge mappings
When running with transparent huge pages and CONFIG_NVHE_EL2_DEBUG then
the debug checking in assert_host_shared_guest() fails on the launch of an
np-guest. This WARN_ON() causes a panic and generates the stack below.
In __pkvm_host_relax_perms_guest() the debug checking assumes the mapping
is a single page but it may be a block map. Update the checking so that
the size is not checked and just assumes the correct size.
While we're here make the same fix in __pkvm_host_mkyoung_guest().

The issue occurs because usbhs_sys_function_pullup(), which accesses the IP
registers, is executed after the USBHS clocks have been disabled. The
problem is reproducible on the Renesas RZ/G3S SoC starting with the
addition of module stop in the clock enable/disable APIs. With module stop
functionality enabled, a bus error is expected if a master accesses a
module whose clock has been stopped and module stop activated.
Disable the IP clocks at the end of remove. |
| NVIDIA Display Driver for Linux contains a vulnerability where an attacker could cause a use-after-free. A successful exploit of this vulnerability might lead to code execution, escalation of privileges, data tampering, denial of service, and information disclosure. |
| The VAPIX Edge storage API that allowed a privilege escalation, enabling a VAPIX administrator-privileged user to gain Linux Root privileges. This flaw can only be exploited after authenticating with an administrator-privileged service account. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/meson: explicitly remove aggregate driver at module unload time
Because component_master_del wasn't being called when unloading the
meson_drm module, the aggregate device would linger forever in the global
aggregate_devices list. That means when unloading and reloading the
meson_dw_hdmi module, component_add would call into
try_to_bring_up_aggregate_device and find the unbound meson_drm aggregate
device.
This would in turn dereference some of the aggregate_device's struct
entries which point to memory automatically freed by the devres API when
unbinding the aggregate device from meson_drv_unbind, and trigger an
use-after-free bug:

mailbox: zynqmp-ipi: Fix SGI cleanup on unbind
The driver incorrectly determines SGI vs SPI interrupts by checking IRQ
number < 16, which fails with dynamic IRQ allocation. During unbind,
this causes improper SGI cleanup leading to kernel crash.
Add explicit irq_type field to pdata for reliable identification of SGI
interrupts (type-2) and only clean up SGI resources when appropriate. |

Soft lockup is not triggered with THP or base page because there is
cond_resched() called for each PMD size.
Although the soft lockup was triggered by MTE, it should be not MTE
specific. The other processing which takes long time in the loop may
trigger soft lockup too.
So add cond_resched() for hugetlb to avoid soft lockup. |
| In the Linux kernel, the following vulnerability has been resolved:
PCI/pwrctrl: Fix double cleanup on devm_add_action_or_reset() failure
When devm_add_action_or_reset() fails, it calls the passed cleanup
function. Hence the caller must not repeat that cleanup.
Replace the "goto err_regulator_free" by the actual freeing, as there
will never be a need again for a second user of this label. |
| In the Linux kernel, the following vulnerability has been resolved:
dccp: Fix out of bounds access in DCCP error handler
There was a previous attempt to fix an out-of-bounds access in the DCCP
error handlers, but that fix assumed that the error handlers only want
to access the first 8 bytes of the DCCP header. Actually, they also look
at the DCCP sequence number, which is stored beyond 8 bytes, so an
explicit pskb_may_pull() is required. |
| In the Linux kernel, the following vulnerability has been resolved:
Squashfs: fix uninit-value in squashfs_get_parent
Syzkaller reports a "KMSAN: uninit-value in squashfs_get_parent" bug.
This is caused by open_by_handle_at() being called with a file handle
containing an invalid parent inode number. In particular the inode number
is that of a symbolic link, rather than a directory.
Squashfs_get_parent() gets called with that symbolic link inode, and
accesses the parent member field.
unsigned int parent_ino = squashfs_i(inode)->parent;
Because non-directory inodes in Squashfs do not have a parent value, this
is uninitialised, and this causes an uninitialised value access.
The fix is to initialise parent with the invalid inode 0, which will cause
an EINVAL error to be returned.
Regular inodes used to share the parent field with the block_list_start
field. This is removed in this commit to enable the parent field to
contain the invalid inode number 0. |
| In the Linux kernel, the following vulnerability has been resolved:
media: pci: mg4b: fix uninitialized iio scan data
Fix potential leak of uninitialized stack data to userspace by ensuring
that the `scan` structure is zeroed before use. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm: fix NULL-deref on snapshot tear down
In case of early initialisation errors and on platforms that do not use
the DPU controller, the deinitilisation code can be called with the kms
pointer set to NULL.

| In the Linux kernel, the following vulnerability has been resolved:
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:
ethtool: eeprom: fix null-deref on genl_info in dump
The similar fix as commit 46cdedf2a0fa ("ethtool: pse-pd: fix null-deref on
genl_info in dump") is also needed for ethtool eeprom. |
| In the Linux kernel, the following vulnerability has been resolved:
arm64/pageattr: Propagate return value from __change_memory_common
The rodata=on security measure requires that any code path which does
vmalloc -> set_memory_ro/set_memory_rox must protect the linear map alias
too. Therefore, if such a call fails, we must abort set_memory_* and caller
must take appropriate action; currently we are suppressing the error, and
there is a real chance of such an error arising post commit a166563e7ec3
("arm64: mm: support large block mapping when rodata=full"). Therefore,
propagate any error to the caller. |
| In the Linux kernel, the following vulnerability has been resolved:
PCI: cadence: Check for the existence of cdns_pcie::ops before using it
cdns_pcie::ops might not be populated by all the Cadence glue drivers. This
is going to be true for the upcoming Sophgo platform which doesn't set the
ops.
Hence, add a check to prevent NULL pointer dereference.
