CVSS v3.1 |
| Net::IP::LPM versions before 1.11 for Perl allow a heap out-of-bounds read via an unbounded prefix length.
add() passes the prefix string to the trie builder addPrefixToTrie() without checking it against the address width.
addPrefixToTrie() then walks the prefix buffer by prefix_length bits, reading prefix[byte] for byte up to prefix_len/8, where prefix is the 4-byte (IPv4) or 16-byte (IPv6) packed address. A prefix length greater than 32 for IPv4 or 128 for IPv6, for example add("1.2.3.4/255", $v) or add("2001:db8::/255", $v), reads past the end of the packed address.
The out-of-bounds read happens during trie construction and is bounded: the prefix length is stored as an unsigned char, so the bit walk reads at most 32 bytes from the start of the packed address, a short distance past the end of the 4-byte or 16-byte buffer. It is detectable under AddressSanitizer, valgrind, or a hardened allocator, where it can abort the process. Lookups and dump() format only the valid address width, so the out-of-bounds bytes are not exposed through the module's API. |
| In geniezone, there is a possible information disclosure due to a missing bounds check. This could lead to local information disclosure if a malicious actor has already obtained the System privilege. User interaction is needed for exploitation. Patch ID: ALPS10867524 / ALPS10876355; Issue ID: MSV-6674. |
| Tobit Laboratories AG TeamDavid's Webbox application handles password changes using a function triggered by
including the string "(editini)" in the file path, writing the new
password to the specified "Archive.ini" file. However, the application
does not verify that the provided path actually refers to an
"Archive.ini" file. If an attacker specifies a different file with
excessive size, a buffer overflow occurs. This vulnerability allows an
unauthenticated attacker to crash the server, resulting in denial of
service. This issue affects TeamDavid before Rollout 528.
Starting with Rollout 528 (June 30, 2026), the affected functionality is disabled by default and the vulnerabilities are therefore no longer exposed through this functionality. |
| A flaw was found in libtpms, a library that provides software TPM 2.0 emulation. When restoring TPM 2.0 state (for example during a virtual machine's power-on or state/migration restore), a malformed state blob can supply an oversized skip-block length that is not validated against the remaining size of the input buffer. This can drive an internal size counter negative, which bypasses a subsequent bounds check due to an unsafe signed-to-unsigned conversion, causing the parser to read memory outside the bounds of the heap buffer holding the state data. Successful exploitation can crash the process hosting libtpms (such as swtpm), resulting in a denial of service of the emulated TPM device and the virtual machine that depends on it. No data corruption or information disclosure was confirmed. |
| Out-of-bounds read vulnerability in Samsung Opensource rLottie allows Overread Buffers.
This issue affects rLottie: 25648aef19187b3f87f4d9420b8d761453ad4630. |
| MOOS-IvP through 24.8.1 contains a buffer over-read vulnerability in isQuoted(), isBraced(), and isChevroned() functions that strip whitespace but index using the original string length. Attackers can send NODE_REPORT messages with leading or trailing whitespace to read past buffer bounds and access adjacent memory. |
| FreeRDP before 3.31.0 contains a heap out-of-bounds read vulnerability in the general_ChromaV1ToYUV444 function during AVC444 chroma plane reconstruction. A malicious RDP server can craft a RFX_AVC444_BITMAP_STREAM with specific frame geometry to trigger an out-of-bounds memory read past the allocated luma plane. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: llcp: bound the connect_sn TLV walk to the skb
Commit 27256cdb290e ("nfc: llcp: bound SNL TLV parsing to the skb and
add length checks") fixed the unbounded TLV walk in nfc_llcp_recv_snl(),
and commit d8bd2dedbde5 ("nfc: llcp: fix OOB read and u8 offset wrap in
TLV parsers") subsequently bounded nfc_llcp_parse_gb_tlv() and
nfc_llcp_parse_connection_tlv(). One sibling parser sharing the same
pattern remains unbounded: nfc_llcp_connect_sn().
nfc_llcp_connect_sn() walks a TLV list, reading a two-byte header
(type, length) followed by length bytes of value, without checking that
the two header bytes or the declared length stay within the buffer. It
returns a pointer to a service name of up to 255 bytes that may point
past the end of the skb; it is subsequently consumed by memcmp() in
nfc_llcp_sock_from_sn(). In addition tlv_array_len was computed as
"skb->len - LLCP_HEADER_SIZE" in size_t, so a CONNECT/CC frame shorter
than the LLCP header underflows to a huge length and the walk runs far
past the buffer.
nfc_llcp_connect_sn() is reachable from nfc_llcp_recv_connect() and
nfc_llcp_recv_cc(), i.e. from received CONNECT and CC PDUs. A nearby
NFC device can reach this without authentication; LLCP link activation
happens automatically after NFC-DEP, and the nfc_llcp_rx_skb()
dispatcher applies no minimum-length guard.
Walk the TLV list by pointer, bounded by skb_tail_pointer(skb), and
validate each declared length before use, matching the approach already
used for nfc_llcp_recv_snl(). Starting the walk at
&skb->data[LLCP_HEADER_SIZE] against the tail pointer also removes the
size_t underflow for short frames.

| In the Linux kernel, the following vulnerability has been resolved:
HID: hyperv: validate initial device info bounds
The Hyper-V synthetic HID host supplies SYNTH_HID_INITIAL_DEVICE_INFO
messages that contain a HID descriptor followed by the report descriptor
bytes. mousevsc_on_receive_device_info() trusts bLength and
wDescriptorLength without checking that the received packet contains both
byte ranges.
A malformed host or backend message can therefore make the guest read
past the received VMBus packet while copying the report descriptor. Pass
the received initial-device-info size into the parser and reject
descriptor lengths that exceed the packet.
Impact: A malicious Hyper-V host or backend can crash a guest by sending
a short initial device-info message with an oversized HID report
descriptor length. |
| In the Linux kernel, the following vulnerability has been resolved:
HID: nintendo: fix out-of-bounds read in joycon_ctlr_read_handler()
joycon_ctlr_read_handler() casts an incoming HID input report to
struct joycon_input_report and parses it, guarding the cast only with a
12-byte length check:
if (size >= 12) /* make sure it contains the input report */
joycon_parse_report(ctlr, (struct joycon_input_report *)data);
struct joycon_input_report is 49 bytes: a 13-byte header followed by a
union whose IMU arm is 36 bytes. For an IMU report joycon_parse_report()
-> joycon_parse_imu_report() walks that union (struct offsets 13..48),
so a report of exactly 12 bytes with data[0] == JC_INPUT_IMU_DATA passes
the guard yet is read up to 37 bytes past its declared length. The
over-read bytes are decoded into accelerometer/gyroscope values and
forwarded to userspace through the "(IMU)" input device, leaking
driver-internal memory. data[0] and size are fully controlled by a
malicious or spoofed Joy-Con/Pro Controller.
Receive buffers are sized to the maximum report length, so this is an
over-read within the allocation rather than a slab OOB, but the decoded
bytes still reach userspace.
The sibling subcmd path in joycon_ctlr_handle_event() already bounds the
same cast correctly:
if (size < sizeof(struct joycon_input_report) ||
data[0] != JC_INPUT_SUBCMD_REPLY)
break;
Use the same sizeof(struct joycon_input_report) bound here. |
| In the Linux kernel, the following vulnerability has been resolved:
ipvs: use parsed transport offset in TCP state lookup
TCP state handling reparses the skb to find the TCP header. For IPv6 it
uses sizeof(struct ipv6hdr), while the surrounding IPVS code already
parsed the packet with ip_vs_fill_iph_skb() and has the real
transport-header offset in iph.len.
This makes TCP state handling look at the wrong bytes when an IPv6
packet carries extension headers. Use the parsed transport offset passed
down from ip_vs_set_state() when reading the TCP header.
For IPv4 and for IPv6 packets without extension headers, the passed
offset matches the previous value. |
| CVE-2026-55402 is an out of bounds read vulnerability in Secure Access
servers prior to version 14.57. Attackers with an ‘in the middle’
position can send specially crafted data to a server causing a
persistent denial of service. |
| In the Linux kernel, the following vulnerability has been resolved:
batman-adv: reject unrepresentable multicast TVLV offsets
The network and transport header fields in struct sk_buff are 16-bit
offsets from skb->head, and U16_MAX is reserved as the unset transport
header value. batadv_tvlv_call_handler() sets both fields from a received
multicast TVLV without checking whether the TVLV end is representable.
If the end offset exceeds the field's range, skb_set_transport_header()
truncates it so that the transport header precedes the network header.
The negative difference is then returned by skb_network_header_len() as
a large u32. batadv_mcast_forw_packet() consequently accepts an oversized
multicast tracker and accesses memory beyond the skb data.
Add skb_set_transport_header_careful(), an offset-aware counterpart to
skb_reset_transport_header_careful(), which validates the final
head-relative offset before assigning it. Use the new helper in
batadv_tvlv_call_handler() and reject unrepresentable TVLVs before
setting the network header. |
| In the Linux kernel, the following vulnerability has been resolved:
USB: serial: option: fix slab OOB read in interrupt URB callback
The interrupt URB buffer is allocated in setup_port_interrupt_in() based
on the endpoint's wMaxPacketSize:
buffer_size = usb_endpoint_maxp(epd);
port->interrupt_in_buffer = kmalloc(buffer_size, GFP_KERNEL);
When a USB device declares wMaxPacketSize = 8 on its interrupt IN
endpoint, the buffer is allocated from kmalloc-8 cache (exactly
8 bytes).
If the device sends a short packet (actual_length < wMaxPacketSize),
the URB completes with status == 0 and the callback proceeds to read:
data[sizeof(struct usb_ctrlrequest)]
which evaluates to data[8], accessing 1 byte beyond the allocated 8-byte
buffer. This results in a slab out-of-bounds read.
Fix this by adding the missing bounds check: first verify that the
actual length is large enough to contain the struct usb_ctrlrequest
header before accessing req_pkt->bRequestType and req_pkt->bRequest,
and then verify that there is an additional byte for the modem signal
state before reading data[sizeof(struct usb_ctrlrequest)] inside the
conditional. Use sizeof(*req_pkt) instead of sizeof(struct
usb_ctrlrequest) for consistency.

| NIOSSLCertificate._subjectAlternativeNames provides access to the raw bytes for a cert's SANs. NIOSSL provides access to a buffer assumed to be backed by an ASN1_STRING, but not all SANs are backed by ASN1_STRING, so accessing the buffer for such a type can lead to out-of-bounds memory access. This vulnerability is addressed in swift-nio-ssl version 2.37.2. |
| MOOS core-moos through 10.4.0 contains a buffer over-read vulnerability in CMOOSCommPkt where a four-byte packet triggers out-of-bounds memory access during deserialization. Attackers can open a TCP connection to the MOOSDB port and send a crafted short packet to read memory before authentication. |
| In the Linux kernel, the following vulnerability has been resolved:
nfc: digital: clamp SENSF_RES length to the destination buffer
digital_in_recv_sensf_res() memcpy()s resp->len bytes from a remote
NFC-F device response into the NFC_SENSF_RES_MAXSIZE-byte target.sensf_res
field without an upper-bound check. A nearby malicious NFC-F device can
send an oversized SENSF_RES response to overflow the stack-local struct
nfc_target.
Clamp resp->len to NFC_SENSF_RES_MAXSIZE before the copy.

| In the Linux kernel, the following vulnerability has been resolved:
xfs: validate attr entry pointer before field access
xfs_attr3_leaf_verify_entry() accesses lentry/rentry fields (namelen,
valuelen) before checking if the entry pointer itself is within bounds.
If nameidx is crafted to point near the end of the buffer, these field
accesses can read out-of-bounds before the bounds check at
name_end > buf_end is performed.
Add explicit bounds checks for entry pointers before accessing their
fields. Use offsetof() to check that the start of the flexible array
member (nameval/name) is within bounds, which ensures all preceding
fields are safe to access. |
| In the Linux kernel, the following vulnerability has been resolved:
Bluetooth: hci_aml: validate firmware segment lengths
aml_download_firmware() reads two lengths from the firmware header and
uses them to build pointers before checking that the header and segment
data are present. A truncated or inconsistent firmware image can make
the driver read past firmware->data while constructing TCI commands.
Reject images shorter than the header and ensure that the ICCM and DCCM
ranges fit within the loaded firmware before downloading either segment. |
| In the Linux kernel, the following vulnerability has been resolved:
ALSA: dummy: Check card index validity at probe
snd_dummy_probe() blindly trusts that the given devptr->id value is
within the proper card index range. It's OK for the devices the
driver itself creates at the module probe time, but if the device is
bound manually via sysfs interface, this could be -1 as "none", and
this leads to OOB access for index[] and other parameters.
Add a sanity check for the card index and warn/correct it if it's a
value out of the range. |
