CVSS v3.1 |
| unarr through 1.1.1 contains a heap-based out-of-bounds read in zip_parse_extra_fields() in zip/parse-zip.c due to an incorrect ZIP64 extra field length check. Attackers can supply a crafted ZIP archive with 0xFFFFFFFF sentinel values and a truncated ZIP64 record to read past the heap buffer and crash the process. |
| Out-of-bounds read in Windows Update allows an authorized attacker to disclose information locally. |
| smpeg through 2.0.0 contains a heap out-of-bounds read vulnerability in MPEGsystem::FillBuffer() that allows attackers to read past the 16384-byte buffer by supplying a crafted system header stream table. Attackers can provide an MPEG file whose stream table bytes all set the high bit, which crashes applications opening it through SMPEG_new, SMPEG_new_rwops, or SMPEG_new_data. |
| libstrophe through 0.14.0 contains a stack-based buffer overflow vulnerability in SCRAM_Hi that allows malicious XMPP servers to overflow a 128-byte stack buffer by sending an oversized SCRAM salt. Attackers can send a server-first-message whose s= attribute decodes to more than 124 bytes, aborting the client or overwriting stack memory in NDEBUG builds. |
| A maliciously crafted PDF file, when parsed through Autodesk Revit, can force an Out-of-Bounds Read vulnerability. A malicious actor can leverage this vulnerability to cause a crash, read sensitive data, or execute arbitrary code in the context of the current process. |
| ExLlamaV3’s EXL3 loader uses an untrusted, model-supplied index to select a CUDA kernel without first verifying that the index is within bounds. A malicious model can force the code to read and invoke an out‑of‑range function pointer, resulting in a reproducible crash. Under specific conditions involving certain host memory layouts, it may be possible for an attacker to exploit this vulnerability to achieve controlled indirect kernel dispatch during model load. |
| A heap-buffer-overflow read vulnerability was found in libaom, the reference AV1 codec implementation. A missing bounds check in the SVC (Scalable Video Coding) layer ID control function allows setting a spatial_layer_id exceeding the configured number of layers. This causes an out-of-bounds heap read of approximately 40,728 bytes when computing a layer context array index. An attacker who can influence SVC encoder parameters in a network-facing service could exploit this for information disclosure (heap content leak) or denial of service (segmentation fault from hitting unmapped memory). |
| A heap buffer overflow vulnerability was found in libaom, the reference AV1 codec implementation. A flaw in the AV1 encoder's Look-Ahead Processing (LAP) mode causes the first-pass stats ring buffer wrap-around guard to be bypassed when g_lag_in_frames is set to 1 or higher. This results in a 232-byte out-of-bounds write on every encoded frame after the second, corrupting adjacent heap objects. An attacker who can influence encoder configuration in a transcoding service or WebRTC session could exploit this to cause a denial of service (process crash) or potentially achieve code execution. |
| A vulnerability was determined in ztxz16 fastllm up to 0.1.8.2. This impacts the function GGUFBuffer::ReadString of the file third_party/gguf/gguf.cpp of the component String Parsing. This manipulation of the argument len causes buffer overflow. The attack can be initiated remotely. The exploit has been publicly disclosed and may be utilized. The project was informed of the problem early through an issue report but has not responded yet. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Restrict CO-RE poisoning to relocatable instructions
CO-RE relocation records can name any instruction offset. When a
relocation cannot be resolved, bpf_core_patch_insn() currently poisons its
target before checking whether that instruction is a valid relocation
target. Malformed metadata can therefore replace jumps, calls, exits,
register-source arithmetic, or non-immediate loads instead of failing at
the relocation step.
Handle poisoning only after the instruction has passed the same class and
operand-form checks used for a resolved relocation. Route invalid forms
through the existing diagnostic and return a hard error. Keep poisoning
supported instructions, including both halves of a plain ldimm64, so an
unresolved relocation in dead code remains valid.
Extend bpf_core_poison_insn() to poison both halves of ldimm64, and return
its status directly from each validated instruction case. This avoids
routing the success path through a common label and leaves the helper free
to report errors.
The shared relocation code applies this restriction to both libbpf and
in-kernel CO-RE. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Check params size before reading reserved fields
bpf_crypto_ctx_create() is a kfunc whose second argument is declared
with the __sz annotation, so the verifier only guarantees that
params__sz bytes of params are valid. The function nevertheless reads
params->reserved[0] and params->reserved[1] (offsets 14 and 15) before
comparing params__sz against the size of struct bpf_crypto_params, so a
BPF program can pass a shorter buffer and have the kernel read past the
region that was validated for it.
Move the size check in front of the reserved field reads. |
| In the Linux kernel, the following vulnerability has been resolved:
bpf: Reject non-negative offsets in stack_slot_obj_get_spi()
bpf_get_spi() computes (-off - 1) / BPF_REG_SIZE using C division,
which truncates toward zero. For off == 0, this produces spi 0, the
same index used by the valid stack slot at fp-8.
stack_slot_obj_get_spi() currently checks alignment and the resulting
spi bounds, but does not reject the non-negative offset itself. It can
therefore validate a PTR_TO_STACK register holding fp+0 against an
iterator stored at fp-8 even though the runtime receives the actual fp+0
pointer. An effectful iterator kfunc can then interpret memory outside
the BPF stack as iterator state.
Reject non-negative offsets before converting the offset to an spi. All
valid stack objects begin at a negative offset from the frame pointer. |
| In the Linux kernel, the following vulnerability has been resolved:
net: usb: sr9700: include receive overhead in the length check
The receive fixup subtracts the Ethernet CRC from the reported packet
length, but compares that payload length against the whole remaining
receive buffer. The following copy starts after the three-byte header,
and the cursor advance consumes both that header and the four-byte CRC.
Require the payload to fit after SR_RX_OVERHEAD before copying it or
advancing to the next packet. The loop already ensures that the
remaining buffer is larger than the overhead, so the subtraction is
safe.
The issue was found by our static-analysis tool. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: pn533: fix OOB read in pn533_acr122_is_rx_frame_valid()
frame->ccid.datalen is read directly from the USB response frame
and used, unchecked, as an index into frame->data[]. A malicious or
malfunctioning device can set this field to an arbitrary value,
causing the driver to read far outside the received buffer.
Bound ccid.datalen against the maximum possible ACR122 frame size
before using it. This replaces the existing datalen == 0 check,
since datalen < 2 already covers that case and additionally
rejects datalen == 1, which would still underflow the
"datalen - 2" offset used below. |
| In the Linux kernel, the following vulnerability has been resolved:
net: ipv6: keep room for the mac header in dst_dev_overhead()
The seg6, ioam6 and rpl lwtunnels size their skb_cow_head() request as
the length they are about to push plus dst_dev_overhead(), then push the
new headers and rebuild the mac header below them with
skb_mac_header_rebuild(). That rebuild needs skb->mac_len of headroom,
but dst_dev_overhead() leaves LL_RESERVED_SPACE() of the egress device,
16 bytes for plain Ethernet.
Where the mac header is longer than that, as it is on ingress through a
VLAN device with reorder_hdr off, the rebuild runs out of room:
skb_set_mac_header(skb, -skb->mac_len) computes a negative offset,
stores it unchecked in the u16 skb->mac_header, and the memmove that
follows writes skb->mac_len bytes about 64 KB past skb->head.
Forwarding plain ping6 traffic through such a device reproduces it on
all five seg6 encapsulation modes and on the rpl and ioam6 inline paths;
skb->mac_header comes back as 65534 on a 704-byte head.
Return the larger of the two. The helper already returns skb->mac_len
when it has no dst, so this only makes the other branch agree, and it
covers every caller rather than each call site in turn. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: wacom: fix OOB read in wacom_wac_pen_serial_enforce()
The 'wacom_wac_pen_serial_enforce()' function may calculate and pass an
invalid offset to hid_field_extract(), resulting in memory reads at
incorrect addresses -- possibly beyond the end of the report. If a
field in the HID descriptor lists more usages than its Report Count
actually reserves space for, the function's inner 'j' will walk past
the end of the field:
for (i = 0; i < report->maxfield; i++) {
for (j = 0; j < report->field[i]->maxusage; j++) {
...
value = hid_field_extract(hdev, raw_data + 1,
offset + j * size, size);
A descriptor listing 12288 usages against Report Count 1 has the loop
extract the usage at index 12287 from bit offset 98296 -- about 12 KB
past a 2-byte received report. The value is stored in
wacom_wac->serial[0] and can reach userspace as an MSC_SERIAL event,
making this an information disclosure.
Clamp the loop to field->report_count, the number of value slots the
report holds. Value slots past the last declared usage are still
scanned; they reuse that usage (HID 1.11, 6.2.2.8).
Verified on v6.12.105 with a UHID reproducer: a 2-byte report from
such a descriptor trips KASAN before the patch and not after it. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: port100: reject frames whose declared length exceeds the received data
port100_recv_response() passes the URB transfer buffer to
port100_rx_frame_is_valid(), which checksums le16_to_cpu(frame->datalen)
bytes of frame->data. datalen is a 16-bit field supplied by the device
and is never checked against the number of bytes actually received
(urb->actual_length), so a device reporting a datalen larger than the
received frame makes port100_data_checksum() read out of bounds past the
transfer buffer.
Reject a response whose declared frame size does not fit the received
length before validating it.
Found by 0sec (https://0sec.ai) using automated source analysis; the
missing bound is evident from source. Compile-tested. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sock: validate event length before filtering
is_filtered_packet() reads the event code from skb->data[0] without first
checking that the skb is nonempty. When an opcode filter is configured,
it also reads the command opcode at offsets 3 or 4 without checking that
a Command Complete or Command Status event is long enough.
hci_send_to_sock() invokes the filter before hci_event_packet() validates
the event header. A malformed event supplied by a controller or a vhci
device can therefore cause an out-of-bounds read.
Keep the unmasked event code for the opcode checks. The masked value is
needed for the 64-bit event bitmap, but using it to identify command events
aliases event codes above 0x3f. In particular, Synchronous Train Complete
(0x4f) was treated as Command Status (0x0f) even though its payload has no
opcode.
Reject actual command events that are too short for the field being
inspected. A truncated command event cannot match a configured opcode. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_sock: reject out-of-range OCF values
The raw HCI socket security filter has 128 OCF bits per supported OGF,
but masks the 10-bit OCF with 127 before looking up the command. An
unprivileged socket can therefore submit a reserved OCF that aliases an
allowlisted command modulo 128.
A conforming controller should reject reserved opcodes. Nevertheless,
the security decision must apply to the opcode that will actually be
sent, especially since controller-specific behavior is outside the host
stack's control.
Reject OCF values that cannot be represented by the security filter
instead of aliasing them onto an unrelated command. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: L2CAP: validate frame length before control and FCS access
l2cap_data_rcv() unpacks either a two-byte or four-byte control field
without first ensuring that it is present. A short ERTM or streaming-mode
frame can therefore cause an out-of-bounds read.
There is a second short-frame case when CRC16 is enabled. After the
control field is pulled, l2cap_check_fcs() subtracts two from skb->len
without checking it. If fewer than two bytes remain, the subtraction
wraps; skb_trim() leaves the buffer unchanged and the subsequent FCS
load reads past the logical end of the frame.
Validate that the frame contains both its control field and, when
enabled, its FCS before either field is accessed. |
