CVE-2026-72310 1 Linux 1 Linux Kernel 2026-08-15 N/A
In the Linux kernel, the following vulnerability has been resolved: smb: client: fix overflow in passthrough ioctl bounds check smb2_ioctl_query_info() validates the PASSTHRU_FSCTL response payload before copying it to userspace. The payload offset and length both come from 32-bit fields. The bounds check currently adds OutputOffset and qi.input_buffer_length directly, so the addition can wrap in 32-bit arithmetic before the result is compared against the response buffer length. A malicious server can use a large OutputOffset and a small OutputCount to make the wrapped sum pass the bounds check. The later copy_to_user() then reads from io_rsp + OutputOffset, outside the response buffer. Use size_add() for the offset plus length check so overflow is treated as out of bounds.
CVE-2026-72225 1 Linux 1 Linux Kernel 2026-08-15 N/A
In the Linux kernel, the following vulnerability has been resolved: jbd2: fix integer underflow in jbd2_journal_initialize_fast_commit() jbd2_journal_initialize_fast_commit() validates journal capacity by checking (journal->j_last - num_fc_blks < JBD2_MIN_JOURNAL_BLOCKS). Both j_last and num_fc_blks are unsigned, so when num_fc_blks exceeds j_last the subtraction wraps to a large value, bypassing the bounds check. The resulting underflow corrupts j_last, j_fc_first, and j_free, leading to journal abort. Fix by checking num_fc_blks against j_last before the subtraction, returning -EFSCORRUPTED.
CVE-2026-72226 1 Linux 1 Linux Kernel 2026-08-15 N/A
In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: prevent TVLV OOB check overflow A TT unicast TVLV contains the number of VLANs stored in it. This number is an u16 and gets multiplied by the size of the struct batadv_tvlv_tt_vlan_data (8 bytes). The size can therefore overflow the u16 used to store the tt_vlan_len. All additional safety checks to prevent out-of-bounds access of the TVLV buffer are invalid due to this overflow. Using size_t prevents this overflow and ensures that the safety checks compare against the actual buffer requirements.
CVE-2026-72060 1 Linux 1 Linux Kernel 2026-08-15 N/A
In the Linux kernel, the following vulnerability has been resolved: net: ethernet: ti: icssg: guard PA stat lookups icssg_ndo_get_stats64() unconditionally calls emac_get_stat_by_name() with FW PA stat names regardless of whether the PA stats block is present on the hardware. emac_get_stat_by_name() already guards the PA stats lookup with `if (emac->prueth->pa_stats)`; when that pointer is NULL the lookup falls through to netdev_err() and returns -EINVAL. Because ndo_get_stats64 is polled regularly by the networking stack this produces thousands of log entries of the form: icssg-prueth icssg1-eth end0: Invalid stats FW_RX_ERROR A secondary consequence is that the int(-EINVAL) return value is implicitly widened to a near-ULLONG_MAX unsigned value when accumulated into the __u64 fields of rtnl_link_stats64, silently corrupting the rx_errors, rx_dropped and tx_dropped counters reported by `ip -s link`. Every other PA-aware code path in the driver is already guarded with the same `if (emac->prueth->pa_stats)` check. Apply the same guard here.
CVE-2026-73645 1 Openzeppelin 1 Openzeppelin Confidential Contracts 2026-08-14 N/A
OpenZeppelin Confidential Contracts is an experimental library for developing applications on the Zama fhEVM. Prior to 0.3.1, the ERC7984 contract tracked confidential total supply with an euint64 value, and an overflowing internal _mint operation could fail silently. The wrap and onTransferReceived functions in contracts/token/ERC7984/extensions/ERC7984ERC20Wrapper.sol did not handle that failure, so a user could transfer the underlying token without receiving the corresponding confidential wrapped token. With the default rate(), the wrapper fills after approximately 18.4 trillion tokens, and subsequent wrapping requests can cause loss of funds. This issue is fixed in version 0.3.1.
CVE-2026-62816 1 Microsoft 20 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 17 more 2026-08-14 8.8 High
Heap-based buffer overflow in Reliable Multicast Transport Driver (RMCAST) allows an unauthorized attacker to execute code over an adjacent network.
CVE-2026-65814 1 Microsoft 20 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 17 more 2026-08-14 7.8 High
Heap-based buffer overflow in Windows Storage Port Driver allows an authorized attacker to elevate privileges locally.
CVE-2026-70638 2 Ggml, Ggml-org 2 Llama.cpp, Llama.cpp 2026-08-14 7.8 High
llama.cpp builds b1886 through b7445 contain an integer overflow vulnerability in the LLaMA-Android JNI wrapper where the new_1batch() function multiplies sizeof(llama_seq_id) by an attacker-controlled n_seq_max parameter without overflow validation, causing heap buffer allocation to wrap and allocate insufficient memory. Attackers can exploit this by providing a crafted n_seq_max value through a malicious model file or JNI call to trigger heap corruption and achieve denial of service or arbitrary code execution on Android applications using the LLaMA-Android binding.
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-2026-70462 2 Rsync Project, Samba 2 Rsync, Rsync 2026-08-14 6.5 Medium
rsync 3.1.0 before 3.5.0 contains a signed integer overflow vulnerability in the I/O timeout implementation that allows attackers to permanently disable connection timeouts by injecting MSG_IO_TIMEOUT messages carrying non-positive (zero or negative) values. Attackers can craft malicious MSG_IO_TIMEOUT messages that cause the timeout variable to wrap to a non-positive value, preventing the timeout check from firing and enabling idle or stalled connections to hold daemon slots indefinitely, leading to resource exhaustion.
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-2026-43627 2 Ggml, Ggml-org 2 Llama.cpp, Llama.cpp 2026-08-14 7.8 High
llama.cpp builds b1283 through b9058 contain an integer overflow vulnerability in the llama_batch_init() function where unchecked multiplications in malloc() calls can wrap past INT32_MAX when computing allocation sizes. Attackers can pass specially crafted parameters to trigger integer overflow, causing heap corruption and potentially achieving arbitrary code execution through subsequent batch operations that write past allocated buffer boundaries.
