| A vulnerability was identified in 03-lovepreetSingh MCP up to f95d035c5317fad81af9828286631053ccb23546. This issue affects the function create_file of the file app/api/mcp/route.ts. Such manipulation of the argument filePath/content leads to path traversal. The attack can be launched remotely. The exploit is publicly available and might be used. This product does not use versioning. This is why information about affected and unaffected releases are unavailable. The project was informed of the problem early through an issue report but has not responded yet. |
| Apache NiFi 2.11.0 supports migrating the contents of a version-controlled Process Group into a Connector using REST API methods that list eligible migration sources and submit migration requests. The framework authorized both methods against the target Connector alone, without evaluating access to the Process Groups involved. The absence of Process Group authorization allowed an authenticated user with read access to a Connector to enumerate the identifiers, names, and flow registry details of version-controlled Process Groups outside the scope of granted read policies. It also allowed a user with write access to a Connector to migrate a Process Group without write access to that Process Group, copying the flow definition, referenced assets, and component state into the Connector, and leaving the source Process Group disabled and renamed. Migration excludes sensitive property values and requires the source Process Group to be stopped with empty queues, which limits the scope of exposure. Apache NiFi installations that do not implement component-level authorization policies for Process Groups are not subject to this vulnerability, because the framework enforces Connector write permissions as the security boundary. Upgrading to Apache NiFi 2.12.0 is the recommended mitigation, which filters migration sources to Process Groups the requesting user is authorized to read, and requires write access to the source Process Group when submitting a migration request. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows TCP/IP allows an authorized attacker to elevate privileges locally. |
| Out-of-bounds read in Windows Error Reporting allows an authorized attacker to elevate privileges locally. |
| Apache NiFi 2.11.0 disabled support for gzip-encoded HTTP requests for the application REST API and rejected requests that included the standard Content-Encoding header indicating gzip encoding. The framework enforcement filter did not check multiple instances of the Content-Encoding header and did not reject non-standard identifiers for gzip encoding, allowing a malicious client to send crafted requests that could consume excessive amounts of memory. Upgrading to Apache NiFi 2.12.0 is the recommended mitigation, which disables decompression of gzip-encoded HTTP requests regardless of header number or encoding identifiers. |
| Use after free in Windows Image Acquisition allows an authorized attacker to elevate privileges locally. |
| Server-side request forgery (ssrf) in Azure AI Foundry allows an unauthorized attacker to elevate privileges over a network. |
| IBM MQ Java and JMS client libraries could allow an authenticated attacker to execute arbitrary code on client applications due to a deserialization filter bypass in exception handling. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: gadget: ffs: fix mm lifetime handling
io_data stores a pointer to the submitting task's mm_struct,
but does not currently hold a reference to it while async
requests are pending.
This can result in a use-after-free if the task exits before
completion handling finishes.
Take a reference with mmgrab() when queuing the read request
and release it with mmdrop() on request completion. |
| In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_fs: Fix Use-After-Free in AIO error path
In ffs_epfile_write_iter() and ffs_epfile_read_iter(), when ffs_epfile_io()
fails with an error other than -EIOCBQUEUED, the io_data structure (`p`) is
freed. However, for AIO operations, the kiocb cancel function was already
armed and kiocb->private was set to `p`.
If a concurrent cancel operation (such as sys_io_cancel()) executes after
ffs_epfile_io() fails but before the function frees `p`, a Use-After-Free
can occur when the cancellation handler accesses the freed pointer.
To securely fix this race condition, we must properly un-arm the
cancellation. Invoking `kiocb->ki_complete()` does exactly this by
acquiring `ctx->ctx_lock` and safely removing the kiocb from the active
sequence. In doing so, it ensures that a parallel io_cancel can no longer
discover the kiocb, effectively closing the race window.
We then return -EIOCBQUEUED to notify the VFS layer that the kiocb has been
consumed and it should avoid attempting to complete the request again or
triggering subsequent completion handlers. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: sony: clean up device list on probe failure
sony_input_configured() adds some controllers to sony_device_list before
HID core registers their input devices. input_register_device() can fail
after the callback returns successfully. sony_probe() then observes that
HID_CLAIMED_INPUT is clear and unwinds, but only stops the HID hardware.
The devres-managed sony_sc is freed while its list node remains linked, so
the next matching controller traverses freed memory.
Initialize the list node and device ID to inactive states. Make list
removal idempotent and run the driver-private cleanup on every probe
failure path. This also makes a second cleanup safe when
sony_input_configured() already unwound a partial initialization before
sony_probe() handles the missing input claim.
Found by 0sec (https://0sec.ai) using automated source analysis;
verified against the HID input registration and probe unwind paths. |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: validate MOVE_RANGE destination size
F2FS_IOC_MOVE_RANGE checks the source range, but not the destination end
before updating i_size. A source hole can expose this: __clone_blkaddrs()
skips NULL_ADDR entries and returns success, so the caller can still extend
the destination inode with unchecked pos_out + len.
Reject destination overflow and use inode_newsize_ok() before extending
the destination inode. |
| In the Linux kernel, the following vulnerability has been resolved:
f2fs: limit recovery filename logging to stored length
F2FS stores recovery filenames as a length plus a fixed-size i_name
buffer. The buffer is not NUL-terminated, but recover_inode() and
recover_dentry() print it with %s.
For a 255-byte filename, recovery logging can read past i_name into the
following raw inode fields.
Print the name with a precision bounded by i_namelen and F2FS_NAME_LEN. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/ttm: Drop tt->restore after successful restore
ttm_pool_restore_and_alloc() can successfully complete the restore
process via ttm_pool_restore_commit(), but tt->restore is not dropped
afterward. As a result, subsequent backup/restore flows observe what
appears to be a completed restore, while in reality shmem handles are
still installed in tt->pages, leading to the stack trace below.
Fix this by freeing and dropping tt->restore in
ttm_pool_restore_and_alloc() upon successful completion of the restore.

bpf: Disable preemption in bpf_get_stackid
The get_perf_callchain call needs disabled preemption plus we need
it disabled as long as we access its returned trace entries buffer.
Note the bpf_get_stackid_pe function is executed already with
preemption disabled. |

KEYS: trusted: Fix TPM teardown ordering
trusted_tpm_exit() drops the TPM chip reference and frees the digest
array before unregistering the trusted key type. key_type_lookup()
holds key_types_sem for reading until the key operation finishes, while
unregister_key_type() takes it for writing. It therefore provides the
synchronization point that must precede backend teardown.
The current order permits this interleaving:
CPU 0 CPU 1
trusted_tpm_exit() key_type_lookup("trusted")
put_device(&chip->dev) trusted_tpm_seal()
kfree(digests) pcrlock()
unregister_key_type() tpm_pcr_extend(..., digests)
CPU 1 can consequently dereference the freed digest array. The chip can
also be released before callbacks stop using it.

mm/migrate_device: clear stale mapping after freeing swapcache
__migrate_device_pages() reads the folio mapping before calling
folio_free_swap(). When folio_free_swap() succeeds, the folio is removed
from the swap cache, but the saved mapping still points to swap_space.
Passing the stale mapping to folio_migrate_mapping() makes it use the
mapped-folio path for a folio that is no longer in swapcache. It can then
operate on swap_space.i_pages with invalid reference accounting,
eventually triggering a folio reference count BUG.
After a successful split, nr still contains the number of pages in the
original large folio, although each resulting page is now a separate
order-0 folio. Reset nr to 1 so each split folio is processed separately,
including its own swapcache removal and mapping lookup.
Refresh the saved mapping after folio_free_swap() so the current folio
state is used during migration. |
| In the Linux kernel, the following vulnerability has been resolved:
cxl/ras: Fix cxl_rch_get_aer_info() out-of-bounds AER register read
cxl_rch_get_aer_info() copies the RCH Downstream Port AER capability from
the RCRB MMIO block using a readl() loop bounded by sizeof(struct
aer_capability_regs). This struct is a software layout and its embedded
struct pcie_tlp_log is larger than the on-wire AER capability. As a
result the loop reads past the mapped AER register block.
The over-read also populates the software-only tail fields including
header_log.header_len. An out-of-range header_len passed to
pcie_print_tlp_log() can then loop past the header log buffer and cause
a second out-of-bounds read.
The read was correct when introduced, but struct pcie_tlp_log has since
grown (Header Log and TLP Prefix Log sizes, header_len and flit fields),
so sizeof(struct aer_capability_regs) no longer matches the physical AER
capability.
Bound the read to the physical AER registers, header through the 16 byte
Header Log. Zero the destination first so the software-only fields are
deterministic. |
| In the Linux kernel, the following vulnerability has been resolved:
nfsd: check nfsd4_acl_to_attr() return value in nfsd4_create()
nfsd4_create() stores the return value of nfsd4_acl_to_attr() in
status, but the switch(create->cr_type) block unconditionally
overwrites it in every branch. ACL translation errors are silently
discarded, and the CREATE proceeds without the requested ACL.
Add an early exit check after nfsd4_acl_to_attr(), matching the
pattern already used in nfsd4_setattr().
[ cel: prefer NFS4ERR_BADTYPE over NFS4ERR_ATTRNOTSUPP ] |
