| NVIDIA TensorRT-LLM contains a vulnerability where an attacker could cause a write-what-where condition. A successful exploit of this vulnerability might lead to data tampering, denial of service, and information disclosure. |
| In the Linux kernel, the following vulnerability has been resolved:
scsi: target: iscsi: Fix CRC overread and double-free in iscsit_handle_text_cmd()
Two latent bugs in the Text-phase handler, both present since the
original LIO integration in commit e48354ce078c ("iscsi-target: Add
iSCSI fabric support for target v4.1"):
1) DataDigest CRC buffer overread (4 bytes past text_in).
text_in is kzalloc()'d at ALIGN(payload_length, 4). rx_size is then
incremented by ISCSI_CRC_LEN to make room for the received DataDigest
in the iovec, but the same (now-bumped) rx_size is passed as the
buffer length to iscsit_crc_buf():
if (conn->conn_ops->DataDigest) {
...
rx_size += ISCSI_CRC_LEN;
}
...
if (conn->conn_ops->DataDigest) {
data_crc = iscsit_crc_buf(text_in, rx_size, 0, NULL);
iscsit_crc_buf() walks rx_size bytes of text_in with crc32c(), so
when DataDigest is negotiated it reads 4 bytes past the end of the
text_in allocation. KASAN reproduces this directly on the unpatched
mainline tree as slab-out-of-bounds in crc32c() called from the Text
PDU path. The OOB bytes feed crc32c() and are then compared against
the initiator-supplied checksum, so the value does not flow back to
the attacker, but the kernel does read past the buffer on every Text
PDU with DataDigest=CRC32C.
Fix by passing the actual padded payload length
(ALIGN(payload_length, 4)) that was used for the kzalloc().
2) Stale cmd->text_in_ptr re-free (double-free) on ERL>0 bad DataDigest
drop.
On DataDigest mismatch with ErrorRecoveryLevel > 0 the handler
silently drops the PDU and lets the initiator plug the CmdSN gap:
kfree(text_in);
return 0;
cmd->text_in_ptr still points at the freed buffer. The next Text
Request on the same ITT re-enters iscsit_setup_text_cmd(), which
unconditionally does
kfree(cmd->text_in_ptr);
cmd->text_in_ptr = NULL;
freeing the same pointer a second time. Session teardown via
iscsit_release_cmd() has the same shape and hits the same double-free
if the connection is dropped before a second Text Request arrives.
On an unmodified mainline tree the bug-1 CRC overread fires first on
the initial valid Text Request and perturbs the subsequent state, so
#4 was isolated by building a kernel with only the bug-1 hunk of this
patch applied plus temporary printk() observability around the three
relevant kfree() sites. The observability prints are not part of
this patch. On that build, a three-PDU Text Request sequence after
login produces two back-to-back splats:
BUG: KASAN: double-free in iscsit_setup_text_cmd+0x??
BUG: KASAN: double-free in iscsit_release_cmd+0x??
showing the same pointer freed in the ERL>0 drop path and again in
iscsit_setup_text_cmd() (next Text Request on the same ITT) and once
more in iscsit_release_cmd() (session teardown). On distro kernels
with CONFIG_SLAB_FREELIST_HARDENED=y (default) the double-free
becomes a remote kernel BUG(); on non-hardened kernels it corrupts
the slab freelist.
Fix by clearing cmd->text_in_ptr after the kfree() in the ERL>0 drop
path. With both hunks applied #4 is directly observable on the stock
tree without observability printks; fixing bug-1 alone would mask #4
less, not more, so the hunks are submitted together.
Both fixes are one-liners. The Text PDU state machine is unchanged and
the wire protocol is unaffected. |
| In the Linux kernel, the following vulnerability has been resolved:
thunderbolt: property: Reject dir_len < 4 to prevent size_t underflow
On the non-root path, __tb_property_parse_dir() takes dir_len from
entry->length (u16 widened to size_t). Two distinct OOB conditions
follow when entry->length < 4:
1. The non-root path begins with kmemdup(&block[dir_offset],
sizeof(*dir->uuid), ...) which always reads 4 dwords from
dir_offset. tb_property_entry_valid() only enforces
dir_offset + entry->length <= block_len, so a crafted entry
with dir_offset close to the end of the property block and
entry->length in 0..3 passes that gate but lets the UUID copy
run off the block (e.g. dir_offset = 497, dir_len = 3 in a
500-dword block reads block[497..501]).
2. After the kmemdup, content_len = dir_len - 4 underflows size_t
to ~SIZE_MAX, nentries becomes SIZE_MAX / 4, and the entry
walk runs OOB on each iteration until an entry fails
validation or the kernel oopses on an unmapped page.
Reject dir_len < 4 on the non-root path *before* the UUID kmemdup,
which closes both holes.
Also move INIT_LIST_HEAD(&dir->properties) up to immediately after
the dir allocation so the new error-return path (and the existing
uuid-alloc failure path) calling tb_property_free_dir() sees a
walkable list rather than the zero-initialized NULL next/prev that
list_for_each_entry_safe() would oops on. |
| HCL DFXAnalytics is affected by a Buffer Overflow vulnerability that can lead to a Denial of Service (DoS). The application fails to properly validate input sizes, allowing an attacker to pass an excessive amount of information into a memory container, which can cause the system to crash or become unresponsive. To mitigate this flaw, comprehensive input length checks must be implemented and enforced on both the client and server sides. |
| In NLnet Labs Unbound up to and including version 1.25.1, when the validator builds the canonical RDATA form for an RRSIG-covered PX/RP/MINFO/SOA RRset, it computes the address of the second embedded domain name as 'datstart + dname_valid(datstart, ...)' and passes it straight to 'query_dname_tolower()' without checking that a second name is actually present in the RDATA. The wire-format parser accepts multi-dname RRs whose RDATA ends after the first name, so an attacker who runs a DNSSEC-signed authoritative server can deliver a record with an absent second domain name (e.g. SOA record) and cause 'query_dname_tolower()' to walk label-by-label through stale bytes in the per-worker 'env->scratch_buffer', past the end of that heap allocation if 'msg-buffer-size' has been lowered from the default. This leads to heap buffer overflow and on a release build the outcome relies heavily on the contents of the buffer tail and the adjacent heap chunk. |

| [This CNA information record relates to multiple CVEs; the
text explains which aspects/vulnerabilities correspond to which CVE.]
The directory and Rock Ridge / SUSP walk in libfsimage's iso9660 driver
derives several lengths directly from attacker-controlled on-disk fields
without validating them:
* The directory loop itself assumes a good record length. This is
CVE-2026-42494.
* The calculation of the System Use area may underflow. This is
CVE-2026-42495.
* The Rock Ridge extension loop assumes a good (inner) record length.
This is CVE-2026-62423.
* The Rock Ridge NM record processing assumes a good entry length.
This is CVE-2026-62424.
* The Rock Ridge CE record processing assumes a good size and offset.
This is CVE-2026-62425. |
| A flaw was found in the GNU Binutils (Binary Utilities) linker. This vulnerability, a heap-buffer-overflow read (CWE-125), occurs when the linker processes a specially crafted 32-bit XCOFF (Extended Common Object File Format) object file. An attacker could exploit this by providing a malicious file, leading to an out-of-bounds read of memory. This can result in information disclosure, potentially revealing sensitive heap data, and a Denial of Service (DoS) due to the linker crashing. |
| Integer Underflow (Wrap or Wraparound) vulnerability in erlang otp erlang/otp (erts modules), erlang otp erts (erts modules) allows Forced Integer Overflow, Excessive Allocation. This vulnerability is associated with program files erts/emulator/beam/external.c, emulator/beam/external.c.
The BIT_BINARY_EXT tag (77) handler in the External Term Format (ETF) decoder accepts an encoding with both length and trailing-bits fields set to zero. The subsequent computation of the bitstring size underflows an unsigned integer, producing a value of roughly 2^64 that is then passed as a memory allocation size. The allocator aborts the entire node with a message such as "Cannot allocate 2305843009213693951 bytes of memory (of type binary)".
The crash is a VM-level abort, not an Erlang-level exception. It cannot be intercepted by supervision trees, by try/catch, or by passing the [safe] option to binary_to_term/2 (which only restricts atom creation and does not perform structural validation of binary encodings).
Any application that decodes ETF from untrusted sources via binary_to_term/1,2 or enif_binary_to_term() is exposed. The Erlang distribution protocol also decodes incoming terms through the same code path, but distribution is expected to run on trusted networks per the OTP Secure Coding Guidelines (DSG-011).
This issue affects OTP from OTP 27.0 before OTP 29.0.4, OTP 28.5.0.4 and OTP 27.3.4.15, corresponding to erts from 15.0 before 17.0.4, 16.4.0.4 and 15.2.7.11. |
| ardupilot through Plane-4.6.3 was found to contain an out-of-bounds read issue in libraries/GCS_MAVLink/GCS_serial_control.cpp in GCS_MAVLINK::handle_serial_control(). |
| Out-of-bounds read, Reachable assertion vulnerability in Samsung Open Source Escargot allows Overread Buffers, Input Data Manipulation.

| RabbitMQ is a messaging and streaming broker. Prior to 4.2.6, RabbitMQ AMQP 0-9-1 allows an existing consumer to keep receiving messages after OAuth token expiry or connection.update_secret refresh to reduced scopes because existing consumers are not canceled or reauthorized at delivery time after the channel user state changes. This issue is fixed in version 4.2.6. |
| Denial-of-service (DoS) vulnerability due to a stack buffer overflow in the http_gdpr_decrypt function of the Mercusys MB115-4G device's web interface. An unauthenticated attacker could exploit this vulnerability by sending a specially crafted request to the /cgi/login endpoint, causing memory corruption and the httpd process to crash, resulting in a denial of service for the web administration service. |
| Insufficient validation of untrusted input in Media in Google Chrome on Windows prior to 150.0.7871.125 allowed a remote attacker who had compromised the renderer process to obtain potentially sensitive information from process memory via a crafted HTML page. (Chromium security severity: High) |
