| 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.

| In the Linux kernel, the following vulnerability has been resolved:
crypto: aspeed - fix double free caused by devm
The clock obtained via devm_clk_get_enabled() is automatically managed
by devres and will be disabled and freed on driver detach. Manually
calling clk_disable_unprepare() in error path and remove function
causes double free.
Remove the manual clock cleanup in both aspeed_acry_probe()'s error
path and aspeed_acry_remove(). |
| In the Linux kernel, the following vulnerability has been resolved:
md/raid10: fix memleak of md thread
In raid10_run(), if setup_conf() succeed and raid10_run() failed before
setting 'mddev->thread', then in the error path 'conf->thread' is not
freed.
Fix the problem by setting 'mddev->thread' right after setup_conf(). |
| In the Linux kernel, the following vulnerability has been resolved:
samples/bpf: Fix buffer overflow in tcp_basertt
Using sizeof(nv) or strlen(nv)+1 is correct. |
| In the Linux kernel, the following vulnerability has been resolved:
platform/x86: alienware-wmi-wmax: Fix NULL pointer dereference in sleep handlers
Devices without the AWCC interface don't initialize `awcc`. Add a check
before dereferencing it in sleep handlers. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio-net: zero unused hash fields
When GSO tunnel is negotiated virtio_net_hdr_tnl_from_skb() tries to
initialize the tunnel metadata but forget to zero unused rxhash
fields. This may leak information to another side. Fixing this by
zeroing the unused hash fields. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: Fix IPsec cleanup over MPV device
When we do mlx5e_detach_netdev() we eventually disable blocking events
notifier, among those events are IPsec MPV events from IB to core.
So before disabling those blocking events, make sure to also unregister
the devcom device and mark all this device operations as complete,
in order to prevent the other device from using invalid netdev
during future devcom events which could cause the trace below.

| In the Linux kernel, the following vulnerability has been resolved:
io_uring/rw: ensure allocated iovec gets cleared for early failure
A previous commit reused the recyling infrastructure for early cleanup,
but this is not enough for the case where our internal caches have
overflowed. If this happens, then the allocated iovec can get leaked if
the request is also aborted early.
Reinstate the previous forced free of the iovec for that situation. |
| In the Linux kernel, the following vulnerability has been resolved:
net: sched: act_connmark: initialize struct tc_ife to fix kernel leak
In tcf_connmark_dump(), the variable 'opt' was partially initialized using a
designatied initializer. While the padding bytes are reamined
uninitialized. nla_put() copies the entire structure into a
netlink message, these uninitialized bytes leaked to userspace.
Initialize the structure with memset before assigning its fields
to ensure all members and padding are cleared prior to beign copied. |
| In the Linux kernel, the following vulnerability has been resolved:
jfs: Verify inode mode when loading from disk
The inode mode loaded from corrupted disk can be invalid. Do like what
commit 0a9e74051313 ("isofs: Verify inode mode when loading from disk")
does. |
| In the Linux kernel, the following vulnerability has been resolved:
smb/server: fix possible memory leak in smb2_read()
Memory leak occurs when ksmbd_vfs_read() fails.
Fix this by adding the missing kvfree(). |
| In the Linux kernel, the following vulnerability has been resolved:
exfat: fix improper check of dentry.stream.valid_size
We found an infinite loop bug in the exFAT file system that can lead to a
Denial-of-Service (DoS) condition. When a dentry in an exFAT filesystem is
malformed, the following system calls — SYS_openat, SYS_ftruncate, and
SYS_pwrite64 — can cause the kernel to hang.
Root cause analysis shows that the size validation code in exfat_find()
does not check whether dentry.stream.valid_size is negative. As a result,
the system calls mentioned above can succeed and eventually trigger the DoS
issue.
This patch adds a check for negative dentry.stream.valid_size to prevent
this vulnerability. |
| In the Linux kernel, the following vulnerability has been resolved:
fscrypt: fix left shift underflow when inode->i_blkbits > PAGE_SHIFT
When simulating an nvme device on qemu with both logical_block_size and
physical_block_size set to 8 KiB, an error trace appears during
partition table reading at boot time. The issue is caused by
inode->i_blkbits being larger than PAGE_SHIFT, which leads to a left
shift of -1 and triggering a UBSAN warning.

This situation can happen for block devices because when
CONFIG_TRANSPARENT_HUGEPAGE is enabled, the maximum logical_block_size
is 64 KiB. set_init_blocksize() then sets the block device
inode->i_blkbits to 13, which is within this limit.
File I/O does not trigger this problem because for filesystems that do
not support the FS_LBS feature, sb_set_blocksize() prevents
sb->s_blocksize_bits from being larger than PAGE_SHIFT. During inode
allocation, alloc_inode()->inode_init_always() assigns inode->i_blkbits
from sb->s_blocksize_bits. Currently, only xfs_fs_type has the FS_LBS
flag, and since xfs I/O paths do not reach submit_bh_wbc(), it does not
hit the left-shift underflow issue.
[EB: use folio_pos() and consolidate the two shifts by i_blkbits] |
| In the Linux kernel, the following vulnerability has been resolved:
platform/x86: int3472: Fix double free of GPIO device during unregister
regulator_unregister() already frees the associated GPIO device. On
ThinkPad X9 (Lunar Lake), this causes a double free issue that leads to
random failures when other drivers (typically Intel THC) attempt to
allocate interrupts. The root cause is that the reference count of the
pinctrl_intel_platform module unexpectedly drops to zero when this
driver defers its probe.
This behavior can also be reproduced by unloading the module directly.
Fix the issue by removing the redundant release of the GPIO device
during regulator unregistration. |
| In the Linux kernel, the following vulnerability has been resolved:
gve: Implement settime64 with -EOPNOTSUPP
ptp_clock_settime() assumes every ptp_clock has implemented settime64().
Stub it with -EOPNOTSUPP to prevent a NULL dereference. |
| In the Linux kernel, the following vulnerability has been resolved:
ntfs3: pretend $Extend records as regular files
Since commit af153bb63a33 ("vfs: catch invalid modes in may_open()")
requires any inode be one of S_IFDIR/S_IFLNK/S_IFREG/S_IFCHR/S_IFBLK/
S_IFIFO/S_IFSOCK type, use S_IFREG for $Extend records. |
| In the Linux kernel, the following vulnerability has been resolved:
gve: Implement gettimex64 with -EOPNOTSUPP
gve implemented a ptp_clock for sole use of do_aux_work at this time.
ptp_clock_gettime() and ptp_sys_offset() assume every ptp_clock has
implemented either gettimex64 or gettime64. Stub gettimex64 and return
-EOPNOTSUPP to prevent NULL dereferencing. |
| In the Linux kernel, the following vulnerability has been resolved:
accel/habanalabs: support mapping cb with vmalloc-backed coherent memory
When IOMMU is enabled, dma_alloc_coherent() with GFP_USER may return
addresses from the vmalloc range. If such an address is mapped without
VM_MIXEDMAP, vm_insert_page() will trigger a BUG_ON due to the
VM_PFNMAP restriction.
Fix this by checking for vmalloc addresses and setting VM_MIXEDMAP
in the VMA before mapping. This ensures safe mapping and avoids kernel
crashes. The memory is still driver-allocated and cannot be accessed
directly by userspace. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_fs: Fix epfile null pointer access after ep enable.
A race condition occurs when ffs_func_eps_enable() runs concurrently
with ffs_data_reset(). The ffs_data_clear() called in ffs_data_reset()
sets ffs->epfiles to NULL before resetting ffs->eps_count to 0, leading
to a NULL pointer dereference when accessing epfile->ep in
ffs_func_eps_enable() after successful usb_ep_enable().
The ffs->epfiles pointer is set to NULL in both ffs_data_clear() and
ffs_data_close() functions, and its modification is protected by the
spinlock ffs->eps_lock. And the whole ffs_func_eps_enable() function
is also protected by ffs->eps_lock.
Thus, add NULL pointer handling for ffs->epfiles in the
ffs_func_eps_enable() function to fix issues |
| In the Linux kernel, the following vulnerability has been resolved:
drm/mediatek: Fix device use-after-free on unbind
A recent change fixed device reference leaks when looking up drm
platform device driver data during bind() but failed to remove a partial
fix which had been added by commit 80805b62ea5b ("drm/mediatek: Fix
kobject put for component sub-drivers").
This results in a reference imbalance on component bind() failures and
on unbind() which could lead to a user-after-free.
Make sure to only drop the references after retrieving the driver data
by effectively reverting the previous partial fix.
Note that holding a reference to a device does not prevent its driver
data from going away so there is no point in keeping the reference. |
