| In the Linux kernel, the following vulnerability has been resolved:
drm/i915/dmc: Add sanity check for DMC load address
For DMC firmware header version 3, the firmware load address is stored
in dmc_info->start_mmioaddr and later used by dmc_load_program().
Unlike the MMIO address table, the firmware load address is not
validated. Add a sanity check to ensure it is within the valid range.
BSpec: 69671, 68378
(cherry picked from commit 5e47ee5c76ca9becde8df4ad5202845b7ffcbc4c) |
| In the Linux kernel, the following vulnerability has been resolved:
drm/exec: don't immediately add prelocked obj to array of locked objs
When a contention is detected the drm_exec object grabs a reference to
the contended object, unlocks all other objects and pre-locks the
contended one before anything else.
The problem is that it is possible that this pre-locked object was about
to be destroyed and drm_exec is now holding the last reference to it.
So we never actually see this pre-locked object again to be explicitly
locked and so also never reserve a slot for a dma_fence object on it.
Should the driver now use drm_exec_for_each_locked_object() to add a new
fence to all locked objects we eventually see a warning or even a
BUG_ON() to prevent random memory corruption.
Fix this by keeping the prelocked object out of the array of locked objs
until it was explicitly mentioned by the driver again.
If the prelocked object is never mentioned again by the driver
just unlock and drop the reference at the end of the locking loop. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: fix GEM object leak on ENOMEM in userptr ioctl
When amdgpu_hmm_range_alloc() fails amdgpu_gem_userptr_ioctl() returns
-ENOMEM right away and skips the cleanup every other error path goes
through. The GEM object, the bo->parent reference on the VM root and the
MMU notifier registration are all left behind.
Use release_object here, not user_pages_done, range is still NULL at
this point.

| In the Linux kernel, the following vulnerability has been resolved:
drm/amdgpu: don't drop the runtime PM reference twice in amdgpu_gpr
amdgpu_debugfs_gpr_read() drops its runtime PM reference right after
reading the wave registers. When copying them to userspace fails, it
jumps to the err label, which drops the reference a second time. A read
into a bad buffer on Navi31 either steals a reference somebody else
holds (power/runtime_usage goes from 1 to 0) or underflows the count:
amdgpu 0000:03:00.0: Runtime PM usage count underflow!
The registers are already in the kernel buffer at that point, so finish
the hardware access first and copy the buffer with a single
copy_to_user() instead of the put_user() loop with its own error path.
(cherry picked from commit 31035bbd74f7c3e10c163db875b8e67f8b50ee6a) |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: libiscsi: Validate the ITT reflected in a Reject PDU
A Reject PDU carries a copy of the header it rejects, and
iscsi_handle_reject() takes the ITT out of that copy to find the task to
clean up:
memcpy(&rejected_pdu, data, sizeof(struct iscsi_hdr));
...
task = iscsi_itt_to_task(conn, rejected_pdu.itt);
That value is whatever the target put there. iscsi_itt_to_task() bounds
the index against cmds_max and checks nothing else, so any task in the
pool can be named, and iscsi_nop_out_rsp() then completes it.
An index that has never been used gives a NULL task->conn: the pool is
zeroed at session setup and conn is assigned only when a task is
allocated. If the task was used and returned, iscsi_complete_task() hits
its WARN_ON_ONCE(task->state == ISCSI_TASK_FREE) and the refcount
underflows. An in-flight SCSI command is completed as successful - a 1
MiB read returned 1048576 with none of its buffer written and no
warning.
Validate the reflected ITT the way iscsi_itt_to_ctask() validates a
command ITT, and require the task to be in flight and not a SCSI
command.

| In the Linux kernel, the following vulnerability has been resolved:
scsi: xen/scsifront: Check for a NULL shadow entry on a backend response
scsifront_do_response() validates the rqid in a backend response against
VSCSIIF_MAX_REQS before using it to index info->shadow[], but then
dereferences the entry to test ->inflight without checking that the slot
is populated. Shadow slots are NULL before a command is submitted (the
host private area is zeroed at allocation) and are reset to NULL in
_scsifront_put_rqid() once a request completes, so an in-range rqid that
does not correspond to an outstanding request makes the frontend
dereference a NULL pointer.
A malicious or buggy backend can thus crash the guest by returning a
response whose rqid is in range but not in flight -- for example a
spurious response before any command has been issued, or a duplicate of
one already completed. The ring has only VSCSIIF_MAX_REQS (16) slots,
so before the first command every in-range rqid selects a NULL slot.
Reject a response whose shadow slot is not populated. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: st: Fix use-after-free race between st_remove() and st_open()
st_remove() drops the probe reference on the scsi_tape with kref_put()
and only afterwards removes its index from st_index_idr. If that was the
last reference, scsi_tape_release() frees the structure while it is
still published in the idr.
scsi_tape_get(), called from st_open(), looks up the tape in
st_index_idr and takes a reference under st_ref_mutex and
st_index_lock. remove_cdevs() does not wait for opens that are already
past chrdev_open(), so an open that is blocked on st_ref_mutex while
st_remove() holds it can take the mutex as soon as st_remove() drops it,
find the freed tpnt in the idr and call kref_get() on it:
BUG: KASAN: slab-use-after-free in st_open
Write of size 4 ...
st_open (drivers/scsi/st.c:254 drivers/scsi/st.c:1291)
chrdev_open
...
Freed by task ...:
kfree
st_remove (drivers/scsi/st.c:4512)
Remove the index from the idr before dropping the reference, all under
st_ref_mutex. A concurrent scsi_tape_get() now either runs first and
holds a valid reference that keeps the tape alive, or runs afterwards
and finds nothing, so st_open() fails with -ENXIO.
This restores the ordering st_remove() had before the conversion to
st_index_idr, where the tape was unpublished from scsi_tapes[] before
the final kref_put(). |
| Observable discrepancy in the CMS RSA PKCS#1 v1.5 key-transport unwrap (KeyTransRecipientInformation.UnwrapKey) in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows a remote attacker who holds a captured CMS EnvelopedData message, and who can submit many modified messages to an application that decrypts them with the recipient's RSA private key and reveals how decryption failed, to recover the captured message's content-encryption key and so its content, via a Bleichenbacher-style adaptive chosen-ciphertext attack, because a key-transport ciphertext with invalid PKCS#1 v1.5 padding is rejected during unwrap with a distinct "bad padding in message." CmsException instead of being replaced by a random key, so it can be told apart from a correctly padded ciphertext, which fails only later at content decryption. |
| OpenHop is a tool for creating interactive data-flow diagrams. Prior to 0.3.7, `@openhop/server` passes unauthenticated flow route parameters from `GET /api/flows/:id` and `DELETE /api/flows/:id` in `packages/server/src/routes.ts` to `FlowStore.filePath()` in `packages/server/src/store.ts` without an identifier allow-list. The router applies `decodeURIComponent` to the id, and `path.join()` then normalizes traversal outside the configured flow directory after appending the .yaml extension. An attacker can read accessible YAML files as YAML-parsed JSON or permanently delete accessible .yaml files outside that directory, exposing configuration or secrets and disrupting dependent services. In `packages/server/src/index.ts`, CORS `origin: true` permits any browser origin, enabling a malicious webpage to target a loopback-bound instance. Docker deployments default to `HOST=0.0.0.0` and permit direct unauthenticated network access. This issue is fixed in repository release 0.3.7. |

| Memory allocation with excessive size value in the OpenPGP signature and user attribute subpacket parsers (SignatureSubpacketsParser.ReadPacket, UserAttributeSubpacketsParser.ReadPacket) in Legion of the Bouncy Castle Inc. bc-csharp before 2.7.0 allows a remote, unauthenticated attacker who can supply a crafted OpenPGP public key, certificate or signature to cause a denial of service (OutOfMemoryException or memory exhaustion in the parsing process) via a subpacket header using the five-octet length form, because the declared length was used to size the subpacket buffer with no upper bound and without being compared with the size of the enclosing subpacket area or packet, so a few bytes of input could demand an allocation of up to about 2 GB before any subpacket data was read. |
| Functype is a family of TypeScript functional programming libraries. Prior to 1.4.4, the `set_functype_version` MCP tool in `functype-mcp-server` accepts an unconstrained `version` string using only `z.string()` validation in `packages/mcp-server/src/index.ts` and interpolates it into `functype@<version>` for `pnpm add`. Package-alias syntaxes such as `file:`, `npm:`, URLs, or paths can cause an arbitrary local or remote package to be installed as functype. Immediately afterward, `initDocsData(true)` in `packages/mcp-server/src/lib/docs/data.ts` resolves `functype/cli` and dynamically imports the newly installed module, executing attacker-controlled JavaScript with the MCP server process's privileges. Any MCP client able to send a `tools/call` request invoking the tool can exploit the flaw; the tool is enabled by default without authentication in `stdio` mode. A connected AI assistant susceptible to indirect prompt injection can also be induced to invoke it from a malicious document or web page. In non-default `TRANSPORT_TYPE=httpStream` deployments, a network-accessible attacker does not require local access. Successful execution can read process secrets, modify files, or terminate the server. This issue is fixed in `version` 1.4.4. |
| Concurrent execution using shared resource with improper synchronization ('race condition') in Windows Connected Devices Platform Service allows an authorized attacker to elevate privileges locally. |
| NORA is a self-hosted artifact registry and pull-through cache. Prior to 0.9.5, `nora-registry` authenticates the token-management UI but fails to require administrator authorization. `auth_middleware()` protects `/ui/tokens` and `/api/ui/tokens`, but state-changing requests are checked only with `role.can_write()`, not `role.can_admin()`. `tokens_page()` and `tokens_list()` call `store.list_all_tokens()`, exposing IDs and metadata across all users, while `tokens_revoke()` calls `store.revoke_token` using the supplied token ID without an ownership or admin check. A read bearer token can enumerate other users' token existence, owner, role, description, expiry and last-use metadata. A write bearer token or write-capable OIDC identity can additionally revoke arbitrary admin and service tokens, disrupting the registry and forcing credential recovery. Read-only identities cannot POST a revocation. This issue is fixed in version 0.9.5. |
