CVE-2026-66374 Jul 25, 00:28 HIGH PATCH This Week

Remote code execution in Knot Resolver versions prior to 6.4.1 stems from a heap-based buffer overflow triggered along the DNS-over-QUIC (DoQ) receive path, allowing a remote unauthenticated attacker to corrupt heap memory by sending malformed QUIC-transported DNS traffic to an exposed resolver. Because the flaw lives in the query-receiving code, any Knot Resolver instance that has DoQ listening is reachable over the network without credentials. Publicly available exploit code exists (a dedicated 'knot-doq' proof-of-concept was published), and the issue was disclosed via oss-security; it is not listed in CISA KEV, so there is no confirmation of active exploitation yet.

Apache Thrift C++ library's THeaderTransport::readString() fails to properly validate info-header length, allowing an out-of-bounds read. An attacker sending a specially crafted Thrift message can trigger this to read beyond the buffer, potentially leaking sensitive memory contents.

Heap out-of-bounds write in FFmpeg's native PNG and APNG encoders (all versions through 8.1.2) allows remote attackers who can supply a crafted PNG image to cause deterministic heap corruption and a potential arbitrary code execution primitive. The root cause is `add_exif_profile_size()` underestimating the required output buffer when multiple EXIF IFD entries share a large value payload - canonical serialization expands the deduplicated entries back to full size, causing `png_write_chunk()` to write tens of thousands of bytes past the allocated boundary. No public exploit exists and EPSS places exploitation probability at 0.55%, but VulnCheck reports the heap corruption is deterministic, elevating the eventual RCE risk.

Denial of service (with potential memory corruption) in select Hikvision network cameras - specifically the DS-2CD and DS-2DE series - lets remote unauthenticated attackers crash or destabilize a device by sending specially crafted packets that trigger a heap buffer overflow. The flaw carries a CVSS 7.7 (AV:N/PR:N) and, per the supplied CVSS vector, high integrity and availability impact, though the vendor advisory characterizes the primary observable effect as device malfunction. No public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV.

Memory corruption in Zephyr RTOS v4.3.0 and v4.4.0 lets any device acting as the I2C bus master corrupt an adjacent target device through the unauthenticated MCTP-over-I2C+GPIO target binding. By selecting the data pseudo-register and writing a byte before sending the length register, an attacker triggers a write through an unallocated (NULL) mctp_pktbuf pointer, and a separate write-then-check bug permits a one-byte heap overflow past data[255]; both yield memory corruption or a hard fault.

Affected versions span rsyslog 7.5.4 through 8.2605.x; the fix is included in 8.2606.0. No public exploit code or active exploitation has been confirmed, but the crash was independently reproduced over both TCP and UDP on Debian 12 with rsyslog 8.2302.0, and the corrective PR (#6991) was merged publicly before coordinated disclosure completed.

Stack out-of-bounds read/write in the Linux kernel i2c-stub driver allows a local user with access to /dev/i2c-* to corrupt kernel stack memory by issuing an I2C_SMBUS ioctl with an oversized block length. The i2c-stub driver's stub_xfer() implements .smbus_xfer directly, bypassing the I2C_SMBUS_BLOCK_MAX (32-byte) length validation applied in the generic i2c_smbus_xfer_emulated() path, meaning data->block[0] values above 32 are accepted and used as a loop bound, reading or writing past the end of the 34-byte union i2c_smbus_data.block buffer onto the kernel stack. No public exploit has been identified at time of analysis and EPSS is 0.17%, but the KASAN trace in the description confirms the crash path is reachable.

Heap buffer overflow in libvips' tiffload operation (versions ≤ 8.18.1) lets an attacker who supplies a crafted TIFF image trigger memory corruption during decode. The flaw stems from libvips incorrectly determining the channel/component count of a JPEG- or JPEG2000-encoded tile embedded in a TIFF, so the pixel buffer is sized from the TIFF photometric metadata while more components are written from the codec. No public exploit has been identified at time of analysis; the issue is fixed in 8.18.2.

The vendor's CVSS vector claims full confidentiality and integrity impact (C:H/I:H) in addition to availability, hinting at possible code execution beyond the DoS described, though the advisory text only states device malfunction. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.

Denial of service (with potential memory corruption) in select Hikvision network cameras - specifically the DS-2CD and DS-2DE series - lets remote unauthenticated attackers crash or destabilize a device by sending specially crafted packets that trigger a heap buffer overflow. The flaw carries a CVSS 7.7 (AV:N/PR:N) and, per the supplied CVSS vector, high integrity and availability impact, though the vendor advisory characterizes the primary observable effect as device malfunction. No public exploit identified at time of analysis, and the vulnerability is not listed in CISA KEV.

CRITICAL PATCH Act Now

Denial of service in FreeRDP servers (versions <=3.27.1) allows unauthenticated remote attackers to crash the service by forging a malicious encrypted client random during RDP Standard Security negotiation. Because the server publishes its RSA public key, an attacker can craft a ciphertext whose decrypted plaintext spans the full RSA modulus (up to 256 bytes for RSA-2048), overflowing a fixed 32-byte heap buffer in crypto_rsa_common() by roughly 224 attacker-controlled bytes before any authentication occurs. No public exploit identified at time of analysis, and the flaw is not listed in CISA KEV; the fix landed in FreeRDP 3.28.0.
