CVSS v3.1 |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to access server resources with the privileges of an authenticated user due to improper authentication during NTLM session negotiation. |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local authenticated attacker to obtain unauthorized access to files due to a time-of-check time-of-use (TOCTOU) race condition. |
| In the Linux kernel, the following vulnerability has been resolved:
iommupt: Check for missing PAGE_SIZE in the pgsize_bitmap
Sashiko pointed out that the driver could drop PAGE_SIZE from the
pgsize_bitmap. That is technically allowed but nothing does it, and
such an iommu_domain would not be used with the DMA API today.
Still, it is against the design and it is trivial to fix up. Lift
the PT_WARN_ON to the if branch and just skip the fast path. |
| In the Linux kernel, the following vulnerability has been resolved:
iommu: Handle unmap error when iommu_debug is enabled
Sashiko noticed a latent bug where the map error flow called iommu_unmap()
which calls iommu_debug_unmap_begin()/iommu_debug_unmap_end() however
since this is an error path the map flow never actually established the
original iommu_debug_map() it will malfunction.
Lift the unmap error handling into iommu_map_nosync() and reorder it so
the trace_map()/iommu_debug_map() records the partial mapping and then
immediately unmaps it. This avoid creating the unbalanced tracking and
provides saner tracing instead of a unmap unmatched to any map. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/msm: Fix iommu_map_sgtable() return value check and avoid WARN
Commit "iommu: return full error code from iommu_map_sg[_atomic]()"
changed iommu_map_sgtable() to return an ssize_t and negative values
in error cases, rather than a size_t and a zero.
Store the return value in the appropriate type and in case of error,
return it rather than WARNing.

| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to execute arbitrary code due to an untrusted search path. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: bpf: Fix hid_bpf_get_data() range check
hid_bpf_get_data() returns a pointer into the HID-BPF context data when
the caller-provided offset and size fit inside ctx->allocated_size.
The current check adds rdwr_buf_size and offset before comparing the
result against ctx->allocated_size. Since both values are unsigned, a
very large size can wrap the sum below ctx->allocated_size and make the
helper return a pointer even though the requested range is not contained
in the backing buffer.
Use check_add_overflow() to reject wrapped range ends before comparing
the requested range end against ctx->allocated_size. |
| In the Linux kernel, the following vulnerability has been resolved:
apparmor: check label build before no_new_privs test
aa_change_profile() builds a replacement label with
fn_label_build_in_scope() before the no_new_privs subset check. The build
helper can fail and return NULL or an ERR_PTR, but the result was passed
to aa_label_is_unconfined_subset() before the existing IS_ERR_OR_NULL()
check.
Reuse the existing target-label build failure handling immediately after
the build. This preserves the current audit handling while preventing the
subset helper from dereferencing an invalid label. |
| Ray is an AI compute engine. Prior to version 2.52.0, developers working with Ray as a development tool can be exploited via a critical RCE vulnerability exploitable via Firefox and Safari. This vulnerability is due to an insufficient guard against browser-based attacks, as the current defense uses the User-Agent header starting with the string "Mozilla" as a defense mechanism. This defense is insufficient as the fetch specification allows the User-Agent header to be modified. Combined with a DNS rebinding attack against the browser, and this vulnerability is exploitable against a developer running Ray who inadvertently visits a malicious website, or is served a malicious advertisement (malvertising). This issue has been patched in version 2.52.0. |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to cause a denial of service due to the use of uninitialized memory during ASN.1 length processing. |
| In the Linux kernel, the following vulnerability has been resolved:
net: qrtr: fix 32-bit integer overflow in qrtr_endpoint_post()
qrtr_endpoint_post() validates an incoming packet with
if (!size || len != ALIGN(size, 4) + hdrlen)
goto err;
where size comes from the wire. On 32-bit, size_t is 32 bits and
ALIGN(size, 4) wraps to 0 for size >= 0xfffffffd, so the check
passes and skb_put_data(skb, data + hdrlen, size) writes past the
hdrlen-sized skb and oopses the kernel. 64-bit is unaffected.
This is the 32-bit residual of ad9d24c9429e2 ("net: qrtr: fix OOB
Read in qrtr_endpoint_post"), which fixed only the 64-bit case.
Reject any size that cannot fit the buffer before the ALIGN. |
| In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: LAG, Fix off-by-one in single-FDB error rollback
On failure at index i, the reverse cleanup loop in
mlx5_lag_create_single_fdb() starts from i, so the failed index
itself is rolled back. That can operate on uninitialized state or
double-tear-down a rule the add_one path already self-rolled-back.
Start the rollback from i - 1 so only successfully-installed entries
are undone. |
| In the Linux kernel, the following vulnerability has been resolved:
dmaengine: Fix possible use after free
In dma_release_channel(), check chan->device->privatecnt after call
dma_chan_put(). However, dma_chan_put() call dma_device_put() which could
release the last reference of the device if the DMA provider is already
gone and hence free it.
Fixes it by moving dma_chan_put() after the check. |
| IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local attacker to gain elevated privileges due to improper privilege management. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/xe/pt: prevent invalid cursor access for purged BOs
During a page table walk for binding, xe_pt_stage_bind() explicitly
skips initializing the xe_res_cursor for purged BOs, treating them
similarly to NULL VMAs by only setting the cursor size.
However, xe_pt_hugepte_possible() and xe_pt_scan_64K() did not check
if the BO was purged before attempting to walk the cursor using
xe_res_dma() and xe_res_next(). Because the cursor was left
uninitialized for purged BOs, this falls through and triggers
warnings like:
WARNING: drivers/gpu/drm/xe/xe_res_cursor.h:274 at xe_res_next
Fix this by explicitly checking if the BO is purged in both
xe_pt_hugepte_possible() and xe_pt_scan_64K(), returning early just
as we do for NULL VMAs, avoiding the invalid cursor accesses entirely.
As a precaution, also zero-initialize the cursor in xe_pt_stage_bind()
to ensure we don't pass garbage data into the page table walkers
if we ever hit a similar edge case in the future.

| In the Linux kernel, the following vulnerability has been resolved:
flow_dissector: check device type before reading ETH_ADDRS
__skb_flow_dissect() unconditionally reads 12 bytes from eth_hdr(skb)
when FLOW_DISSECTOR_KEY_ETH_ADDRS is requested. This assumes the skb
has a valid Ethernet header at mac_header, which is not always the case.
The problem can be triggered by:
1. Creating a TUN device in L3 mode (IFF_TUN, hard_header_len=0)
2. Attaching a multiq qdisc with a flower filter matching on eth_src
3. Sending a packet through AF_PACKET
Since TUN in L3 mode has no link-layer header, mac_header points to
the L3 data area. The flow dissector reads 12 bytes of uninitialized
skb memory, which then propagates through fl_set_masked_key() and is
used as a rhashtable lookup key in __fl_lookup(), as reported by KMSAN.
Rejecting the filter in the control path (at tc filter add time) is
not feasible because TC filter blocks can be shared between arbitrary
devices -- a filter installed on an Ethernet device may later classify
packets on a headerless device through a shared block. The device
association is not fixed at filter creation time.
Fix this by gating the memcpy on dev->type == ARPHRD_ETHER, which
ensures only true Ethernet-framed packets have their addresses read.
This is more precise than the previous hard_header_len >= 12 check,
which would incorrectly pass for non-Ethernet link types like IPoIB
(ARPHRD_INFINIBAND, hard_header_len=24) and FDDI (hard_header_len=21)
whose L2 headers are not in Ethernet format. Additionally check
skb_mac_header_was_set() to guard against the pathological case where
mac_header is the unset sentinel (~0U), which would cause eth_hdr() to
return a wild pointer.
For the act_mirred redirect case (Ethernet packet redirected to a
non-Ethernet device sharing a TC block), zeroing the key is the correct
behavior: the packet is now being classified on the target device, where
Ethernet address matching is not semantically meaningful.
Note: on non-Ethernet devices, the zeroed key will match a filter
configured with all-zero MAC addresses. This is an improvement over the
previous behavior where uninitialized memory could randomly match any
filter. |
| In the Linux kernel, the following vulnerability has been resolved:
ASoC: fsl: fsl_audmix: Validate written enum values
fsl_audmix_put_mix_clk_src() and fsl_audmix_put_out_src()
convert the user-provided enum item with snd_soc_enum_item_to_val()
before checking whether the item is within the enum's item count.
The generic snd_soc_put_enum_double() helper performs that
validation, but these callbacks use the converted value first: the
clock-source path tests it with BIT(), and the output-source path
indexes the prms transition table with it.
Reject out-of-range enum items before converting them. |
| Scriban before 6.6.0 contains an uncontrolled recursion vulnerability in its recursive-descent parser. The parser does not enforce a default expression depth limit (the ExpressionDepthLimit property in ParserOptions defaults to null/disabled), so an attacker who controls template input can supply a deeply nested template (e.g., thousands of nested parentheses or blocks) that exhausts thread stack space and raises a StackOverflowException. Because a StackOverflowException cannot be caught in .NET, this causes immediate, unrecoverable termination of the hosting process, resulting in a denial of service. Applications that process untrusted or user-supplied templates can be exploited remotely without authentication. |
| Scriban versions from 3.0.0 through 7.2.5 contain a denial of service vulnerability in the ScriptRange.Multiply operator that bypasses LoopLimit when the left operand is a lazy sequence. Attackers can supply templates with array multiplication on lazy sequences to execute billions of uncharged iterations, pinning CPU cores and exhausting garbage collection resources even when LoopLimit is set to 1. |
| The Grav API plugin (getgrav/grav-plugin-api) versions >= 1.0.6 and <= 1.0.11 contain a privilege escalation vulnerability. A scoped API key minted on a super-admin account bypasses its declared scope cap on four isSuperAdmin()-gated write endpoints (in GroupsController, AccountsConfigController, PreferencesController, and DashboardWidgetController). These endpoints authorize via a super-admin early-return that never invokes requirePermission()—the sole enforcement point of the scope cap—so a 'read-only'-scoped key (e.g. api.pages.read) can perform super-only write operations, including rewriting group ACL maps to grant super-admin privileges to arbitrary accounts. A leaked or delegated read-only CI/monitoring key can therefore gain full super-admin write capability. Fixed in 1.0.13. |
