CVSS v3.1 |
| NVIDIA vGPU Virtual GPU Manager for Linux contains a vulnerability in the kernel mode layer where an attacker could cause an incorrect numeric conversion. A successful exploit of this vulnerability might lead to code execution, denial of service, escalation of privileges, information disclosure, and data tampering. |
| Incorrect conversion between numeric types in Microsoft JScript allows an unauthorized attacker to execute code over a network. |
| LibRaw 0.22.0 contains an incorrect numeric conversion vulnerability in LibRaw::parse_tiff_ifd() when processing TIFF tag 0x00fe (NewSubfileType). A specially crafted RAW, TIFF, or DNG file can supply an attacker-controlled NewSubfileType value outside the range of a signed int. The parser converts this value and narrows it to int without performing range validation. This out-of-range conversion triggers undefined behavior, resulting in process termination and denial of service. |
| NanoSVG 239e102ec contains an incorrect numeric conversion vulnerability in nsvg__curveDivs() during SVG stroke rasterization. A specially crafted SVG document containing an extremely large stroke-width can cause floating-point rounding to produce a zero subdivision angle. The subsequent arc division yields infinity, which is converted to int without range validation, resulting in undefined behavior and process termination, leading to denial of service. |
| MuJS e892c9fdb contains an incorrect numeric conversion vulnerability in jsR_isindex() in jsrun.c. A specially crafted JavaScript input containing an excessively large numeric array index can cause an out-of-range floating-point value to be converted to an integer without proper range validation. This results in undefined behavior and can cause process termination, leading to denial of service. |
| NanoSVG commit 239e102ec contains an incorrect numeric conversion vulnerability in the rasterizer's nsvg__addActive() function. A specially crafted SVG document containing sufficiently large geometry coordinates can cause fixed-point-scaled edge coordinates to exceed the range representable by int. The rasterizer subsequently converts these values to int without range validation, resulting in undefined behavior and possible process termination, leading to denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
xfs: fix unit conversions in per_binval computation
LOLLM noticed that we're doing the unit conversion in the per_binval
computation backwards -- xfs_buf_inval_log_space's second parameter is
supposed to be in bytes, but max_binval is in units of fsblocks. Hence
the conversion should be FSB -> B, not the other way around. |
| In the Linux kernel, the following vulnerability has been resolved:
drm/gud: validate GUD_ROTATION_0 is present in supported rotations
The rotation argument to drm_plane_create_rotation_property() is set to
DRM_MODE_ROTATE_0, and the device reported rotation bitmask is used as
the supported_rotations argument. The driver never validates that
GUD_ROTATION_0 is present, so a device that omits it from its
GUD_PROPERTY_ROTATION triggers the
WARN_ON(rotation & ~supported_rotations) in
drm_plane_create_rotation_property()
Fix this by skipping the creation of rotation property if the device
doesn't have the GUD_ROTATION_0 bit |
| In the Linux kernel, the following vulnerability has been resolved:
gfs2: move quota_init qc iterator increment
Move qc++ from the loop body into the for-loop increment
expression in gfs2_quota_init().
This keeps iterator progression explicit and avoids mixing pointer
advance with duplicate-slot handling in the loop body. |
| Incorrect Calculation vulnerability in RTI Connext Professional (Core Libraries) allows Abuse Existing Functionality. This issue affects Connext Professional: from 7.4.0 before 7.7.0.1, from 7.0.0 before 7.3.1.6, from 6.1.0 before 6.1.*, from 6.0.0 before 6.0.*, from 5.3.0 before 5.3.*, from 5.2.0 before 5.2.*, from 4.1x before 5.1.*. |
| Out-of-bounds Read, Function Call With Incorrect Number of Arguments, Access of Resource Using Incompatible Type ('Type Confusion') vulnerability in RTI Connext Professional (Core Libraries) allows Overread Buffers. This issue affects Connext Professional: from 7.4.0 before 7.7.0.1, from 7.3.0 before 7.3.1.6, from 6.1.2.21 before 6.1.*. |
| Out-of-bounds Read, Function Call With Incorrect Number of Arguments, Access of Resource Using Incompatible Type ('Type Confusion') vulnerability in RTI Connext Professional (Core Libraries) allows Overread Buffers. This issue affects Connext Professional: from 7.4.0 before 7.7.0.1, from 7.3.0 before 7.3.1.6. |
| An incorrect numeric conversion in the JSON parsing component of the MongoDB C Driver's BSON library may cause an unusually large text value to be silently shortened, or the corresponding field to be omitted, while the parsing operation still reports success and returns no error. An unauthenticated party who can supply the input processed by an application that uses this component may cause that application to hold data that does not match what was submitted, which may result in unintended alteration of data. |
| An incorrect numeric type conversion in the BSON document building component of the MongoDB C++ Driver may cause a length value to be interpreted incorrectly. When an application supplies an extremely large, non-terminated field name to the builder, the library may read memory outside the intended buffer and terminate the calling process. No authentication is required, but the calling application must pass the oversized name in a specific form. |
| In the Linux kernel, the following vulnerability has been resolved:
ceph: properly decrypt filenames in vmalloc() buffers
The fscrypt subsystem uses the scatterlist crypto API, inheriting its
requirement that any buffers are in the linear mapping region. However,
the messenger client uses kvmalloc() to create buffers for messages,
which will occasionally place those buffers in the vmalloc() region when
physical memory fragmentation doesn't permit a large enough kmalloc().
The various callers of ceph_fname_to_usr() directly pass (slices of) raw
messages from the MDS without considering that the messages may be in
vmalloc() buffers, resulting in oopses especially on non-x86 platforms
(see 'Closes:' for more details and a reproducer).
Make ceph_fname_to_usr() explicitly tolerant of vmalloc()-allocated
fname->ctext, fname->name, and/or oname->name buffers, using `tname`
(which, when non-null, must be a linear address; when null, is briefly
allocated as necessary) as a bounce buffer to avoid passing any
inappropriate addresses to fscrypt_fname_disk_to_usr().
Additionally change parse_reply_info_readdir() -- the only function to
supply its own `tname` -- to follow the new "tname must never come from
vmalloc()" rule by passing NULL when the message is not in the linear
region. Though this causes a per-dentry kmalloc()+kfree(), this overhead
exists only when processing the minority of messages that spill into
vmalloc(). My (crude) testing puts this at only about 1 in 8,000 readdir
messages. Still, if the overhead proves unreasonable in the future, it
is easy enough to mitigate: a future change could allocate a bounce
buffer in parse_reply_info_readdir() and use that as `tname` instead. |
| An integer overflow was addressed with improved input validation. This issue is fixed in Safari 26.6.1, iOS 26.6.1 and iPadOS 26.6.1, macOS Tahoe 26.6.2, tvOS 27, visionOS 27, watchOS 27. Processing maliciously crafted web content may lead to memory corruption. |
| In the Linux kernel, the following vulnerability has been resolved:
virtio-net: Ensure that TCP packets don't overflow gso_segs
The user can specify any gso_size in a packet crafted with an AF_PACKET
PACKET_VNET_HDR socket, even smaller than TCP_MIN_GSO_SIZE = 8. At the
same time, GSO_MAX_SIZE = 8 * GSO_MAX_SEGS = 8 * 65535. When the user
crafts a packet with gso_size < 8, there is a risk for partial GSO to
overflow the 16-bit gso_segs field when dividing the SKB length by
gso_size.
Adjust gso_size of TCP packets to be at least TCP_MIN_GSO_SIZE = 8. Keep
gso_size of UDP GSO packets, as gso_size=1 is valid and explicitly
tested at tools/testing/selftests/net/tun.c:649. |
| In the Linux kernel, the following vulnerability has been resolved:
net: stmmac: restore NET_IP_ALIGN in the RX DMA offset
Since the RX path was converted to zero-copy, the page pool page is handed
to the stack directly as the skb head, and the offset the DMA engine writes
at is what determines the alignment of the packet headers.
Before the conversion the payload was copied into an skb obtained from
napi_alloc_skb(), which reserves NET_SKB_PAD + NET_IP_ALIGN. The
conversion moved the headroom into stmmac_rx_offset() but did not carry
over NET_IP_ALIGN, so on architectures where NET_IP_ALIGN is 2 the IP
header now lands misaligned:
64 (NET_SKB_PAD) + 14 (ethernet) + 20 (IP) = 98
Same for the XDP branch:
256 (XDP_PACKET_HEADROOM) + 14 (ethernet) + 20 (IP) = 290
On ARM32 this is fatal, because ldm and ldrd trap on unaligned addresses
even when CONFIG_HAVE_EFFICIENT_UNALIGNED_ACCESS is set.
Any received echo request panics the machine, e.g:

Code: e24dd068 e59020a0 e28dc010 e0822001 (e8920003)
Kernel panic - not syncing: Fatal exception in interrupt
The faulting instruction is the ldm of *icmp_hdr(skb) in icmp_echo().
Fix by adding NET_IP_ALIGN back to the RX offset, which restores the
alignment the stack used to get.
Note that commit a955318fe67e ("stmmac: align RX buffers") made a similar
change in 2021 and was reverted by commit 12d125b4574b ("stmmac: Revert
"stmmac: align RX buffers"") because it caused packet corruption. That
patch raised the offset from 0 without adjusting the buffer size
accounting, so the DMA engine could arguably write past the end of the RX
buffers, though this was never root caused.
Commit df542f669307 ("net: stmmac: Switch to zero-copy in non-XDP RX
path") since derives the page pool allocation from stmmac_rx_offset(), so
the extra bytes are accounted for. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sched: fq_codel: clamp default quantum and mtu
fq_codel_init() sets q->quantum = psched_mtu(qdisc_dev(sch)) without
clamping. A device with a huge MTU (e.g. dummy with max_mtu == 0
accepting MTU 2147483634) makes psched_mtu() return 0x80000000, which
overflows the signed flow->deficit to INT_MIN in fq_codel_dequeue(),
causing an infinite loop and soft lockup. Emulate fq_codel_change()
and constrain to [256, FQ_CODEL_QUANTUM_MAX].
The same unclamped psched_mtu() is assigned to q->cparams.mtu a bit
below, and fq_codel_change() never updates it. codel_should_drop()
tests "*backlog <= params->mtu"; with mtu == 0x80000000 (~2 GiB) and
the default 32 MiB memory_limit, the test is always true, so CoDel is
silently and completely disabled (no drops, no ECN). Declare a single
clamped mtu and assign both q->quantum and q->cparams.mtu from it,
which also removes the double psched_mtu() call.
Conditions to recreate the bug: a device whose MTU (plus
hard_header_len) wraps psched_mtu() into the sign bit (e.g. a dummy
device with max_mtu == 0 accepting MTU 2147483634). Requires
CAP_NET_ADMIN in a user namespace. |
| In the Linux kernel, the following vulnerability has been resolved:
net/sched: hhf: clamp quantum before hhf_change() to avoid overflow
hhf_init() sets q->quantum = psched_mtu(qdisc_dev(sch)) with no overflow
check. A device with a huge MTU (e.g. dummy with max_mtu == 0 accepting
MTU 2147483634) makes weight * quantum overflow the signed deficit in
hhf_dequeue(), spinning forever.
Clamp q->quantum before hhf_change() so both the opt and !opt paths see
a sane quantum. Without this, bare "tc qdisc add ... hhf" succeeds with
a clamped quantum but "tc qdisc add ... hhf limit 1000" (any option
present) fails with -EINVAL because hhf_change() re-validates the
unclamped default (sch_hhf.c:559). 256 matches fq_codel's floor and is
a sane minimum for a DRR quantum.
Conditions to recreate the bug: a device whose MTU (plus
hard_header_len) wraps psched_mtu() into the sign bit (e.g. a dummy
device with max_mtu == 0 accepting MTU 2147483634). Requires
