CVE-2026-16692 1 Ibm 1 I 2026-08-14 6.5 Medium
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to cause a denial of service due to a stack-based buffer overflow.
CVE-2026-71969 1 Op-tee 1 Op-tee Os 2026-08-14 6.7 Medium
OP-TEE OS through 4.10.0, fixed in commit 7b8b494, contains a buffer underwrite vulnerability in the RSA NOPAD encrypt and decrypt operations within the mbedTLS software backend and SE050 hardware driver that allows a malicious Trusted Application to corrupt secure-world heap memory by supplying an input length exceeding the RSA modulus size. When src_len exceeds rsa_len, the subtraction expression wraps to a large unsigned value, causing a subsequent memcpy to write attacker-controlled data before the destination buffer in S-EL1 secure-world heap memory.
CVE-2026-70632 1 Ffmpeg 1 Ffmpeg 2026-08-14 7.8 High
FFmpeg versions from 4.4 up to, but not including, 9.0 contain an out-of-bounds heap write vulnerability in the native GoPro CineForm HD (CFHD) decoder that allows remote attackers to corrupt heap memory by supplying a crafted AVI file during stream probing. The cfhd_decode() function fails to enforce the non-Bayer logical output-width invariant in the transform-type-2 reconstruction path, causing horiz_filter_clip() to write oversized 16-bit sample rows far beyond the allocated output frame buffer, which can be escalated to arbitrary code execution via overwrite of a live cleanup callback pointer.
CVE-2026-70628 1 Ffmpeg 1 Ffmpeg 2026-08-14 7.8 High
FFmpeg versions from 0.5 up to, but not including, 9.0 contain a signed integer overflow vulnerability in the DVB subtitle parser in libavcodec/dvbsub_parser.c that allows attackers to trigger a heap buffer overflow by supplying a crafted WTV file. The overflow causes the bounds-check guard expression to wrap to INT_MIN, bypassing the PARSE_BUF_SIZE comparison and invoking memcpy() with attacker-controlled data into a heap buffer, resulting in an out-of-bounds heap write and potential memory corruption or code execution.
CVE-2026-70461 2 Rsync Project, Samba 2 Rsync, Rsync 2026-08-14 8.2 High
rsync 3.2.5 before 3.5.0 contains a heap out-of-bounds write vulnerability that allows remote unauthenticated attackers to write one attacker-controlled byte past the end of a heap allocation by supplying a crafted files-from entry. Attackers can trigger the vulnerability against a read-only rsync daemon module by providing a files-from entry containing both an interior and trailing backslash, causing the add_implied_include() function to under-count the trailing backslash when sizing the destination buffer.
CVE-2026-70458 2 Rsync Project, Samba 2 Rsync, Rsync 2026-08-14 8.2 High
rsync 3.0.0 before 3.5.0 contains an out-of-bounds write vulnerability that allows attackers to corrupt memory by triggering HLINK_BUMP processing on file entries with the FLAG_HLINKED flag set while the hard-link preservation option is inactive. Attackers can exploit the missing F_SUM field in the file_struct layout to access memory past the end of the allocated structure, corrupting adjacent heap or stack data.
CVE-2026-70457 2 Rsync Project, Samba 2 Rsync, Rsync 2026-08-14 6.5 Medium
rsync 3.2.3 before 3.5.0 contains an out-of-bounds write in parse_size_arg() where the return value of snprintf() is used directly as an index into a .bss-segment array without bounds checking. When snprintf truncates the formatted size string, the return value equals the number of characters that would have been written including the truncated portion, and this value may exceed the array length. The subsequent indexed write targets memory outside the intended array bounds, corrupting .bss memory.
CVE-2026-70456 2 Rsync Project, Samba 2 Rsync, Rsync 2026-08-14 8.2 High
rsync 3.0.1 before 3.5.0 contains an out-of-bounds write vulnerability in the read_args() function that allows a malicious sender to corrupt adjacent heap memory by sending a crafted argument list. When the argument count causes the argv allocation to be exactly full, the trailing NULL terminator is written one slot beyond the allocation boundary, corrupting adjacent heap memory.
CVE-2026-60094 1 Vinchin 2 Backup & Recovery, Vinchin Backup And Recovery 2026-08-14 6.5 Medium
Vinchin Backup & Recovery through 9.0.0.86562 contains a heap buffer overflow vulnerability that allows unauthenticated remote attackers to cause process crash or memory corruption by sending a malformed TCP packet with an unchecked body_len field to the agentlink_server service. Attackers can craft a malicious packet that passes an attacker-controlled length directly to recv(), triggering a heap overflow of up to approximately 4 GiB and resulting in process crash or potential memory corruption.
CVE-2026-5857 1 Contiki-ng 1 Contiki-ng 2026-08-14 8.1 High
Contiki-NG's MQTT client parse_publish_vhdr() in os/net/app-layer/mqtt/mqtt.c sets topic_len_received=1 before checking topic_len against the 64-byte limit, so an over-length topic returns early but leaves the flag set. On the next TCP segment, tcp_input() re-invokes the parser with topic_received==0, and the persisted topic_len_received==1 skips the length-reading block containing the guard, falling through directly to a memcpy() that uses the unvalidated 16-bit topic_len as the copy length. The 65-byte topic[] destination overruns into adjacent struct fields including the payload_chunk pointer, which subsequent MQTT code dereferences, giving a compromised or attacker-controlled broker an arbitrary-pointer-write primitive. Contiki-NG's MQTT implementation has no TLS support so the connection is plaintext. Impact ranges from information disclosure and denial of service to remote code execution on embedded targets without memory protection.
CVE-2026-53792 2 Rsync Project, Samba 2 Rsync, Rsync 2026-08-14 6.5 Medium
rsync before 3.5.0 contains an out-of-bounds read vulnerability in the sender-side block matching logic that allows a malicious receiver to trigger memory access before the start of an allocated buffer by sending a crafted checksum block with a length of zero. Attackers can send a specially crafted checksum set containing a zero-length block to cause a negative offset calculation during delta computation, resulting in an out-of-bounds read of file data buffer memory on the sender side.
CVE-2026-43629 2 Ggml, Ggml-org 2 Llama.cpp, Llama.cpp 2026-08-14 8.1 High
llama.cpp builds b4882 through b9058 contain a heap buffer overflow vulnerability in the KV cache state restore path where the state_read_data() function computes write size without overflow checking, allowing attackers with write access to the slot_save_path directory to corrupt heap memory. Attackers can craft malicious state files where cell_count multiplication overflows or exceeds tensor buffer allocation to write attacker-controlled bytes past buffer boundaries, potentially resulting in heap metadata corruption, model weight corruption, or arbitrary code execution via function pointer overwrite.
CVE-2026-29035 1 Civetweb Project 1 Civetweb 2026-08-14 6.5 Medium
CivetWeb (commit 4a4f0c95) contains a heap and stack buffer overflow vulnerability in the read_websocket() function that allows unauthenticated remote attackers to corrupt memory by sending compressed WebSocket frames when both USE_ZLIB and MG_EXPERIMENTAL_INTERFACES are defined. Attackers can negotiate permessage-deflate during the WebSocket handshake and send a crafted frame with the RSV1 bit set, causing the server to write a 4-byte zlib sync trailer out-of-bounds past the allocated buffer, leading to heap metadata corruption, denial of service, or potential code execution.
CVE-2021-47781 1 Cmder 1 Cmder 2026-08-14 9.8 Critical
Cmder Console Emulator 1.3.18 contains a buffer overflow vulnerability that allows attackers to trigger a denial of service condition through a maliciously crafted .cmd file. Attackers can create a specially constructed .cmd file with repeated characters to overwhelm the console emulator's buffer and crash the application.
CVE-2026-13196 2026-08-14 N/A
Nozomi Networks Labs identified a CWE-787: Out-of-bounds Write vulnerability in the process-image management functionality of KUNBUS piControl in version 2.6.2 that allows a local authenticated attacker with device configuration access to write attacker-controlled data outside the bounds of the process-image buffer and corrupt adjacent kernel memory, resulting in kernel memory corruption and denial of service, by supplying crafted device configuration data and crafted input through the piControl character device.

IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local authenticated attacker to generate a stack-based buffer overflow in the Native IBM i JSSE provider, caused by improper bounds checking during TLS session establishment. A local attacker could overflow a fixed-length buffer and execute arbitrary code on the system or cause the JVM process to crash.
CVE-2026-18086 1 Ibm 1 I 2026-08-14 4.5 Medium
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a local attacker to execute arbitrary code or cause a denial of service due to improper bounds checking.
CVE-2026-17502 1 Ibm 1 I 2026-08-14 8.6 High
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote attacker to cause a denial of service due to an out-of-bounds write.
CVE-2026-53202 1 Linux 1 Linux Kernel 2026-08-14 7.8 High
In the Linux kernel, the following vulnerability has been resolved: accel/ivpu: Fix signed integer truncation in IPC receive Fix potential buffer overflow where firmware-supplied data_size is cast to signed int before being used in min_t(). Large unsigned values (>= 0x80000000) become negative, causing unsigned wraparound and oversized memcpy operations that can overflow the stack buffer. Change min_t(int, ...) to min() as both values are unsigned and can be handled by min() without explicit cast.
CVE-2026-17223 1 Ibm 1 I 2026-08-14 8.8 High
IBM i 7.6, 7.5, 7.4, and 7.3 could allow a remote authenticated attacker to execute arbitrary code due to a buffer overflow.
