CVE-2026-48706 1 Envoyproxy 1 Envoy 2026-06-26 5.9 Medium
Envoy is an open source edge and service proxy designed for cloud-native applications. From 1.34.0 until 1.35.13, 1.36.9, 1.37.5, and 1.38.3, a vulnerability exists in Envoy's TCP StatsD sink (TcpStatsdSink), where the thread-local flusher buffer can be overflowed by exceptionally long statistic names (e.g., >16KiB). During formatting, TcpStatsdSink reserves a single contiguous memory slice of 16KiB (FLUSH_SLICE_SIZE_BYTES). If formatting a single metric exceeds the remaining capacity, the flusher initiates a buffer rotation but incorrectly continues to allocate another fixed 16KiB slice. If an attacker can trigger a statistic name longer than 16KiB—for example, by sending an HTTP or gRPC request with an extremely long request path (:path) that is recorded by the grpc_stats filter configured with stats_for_all_methods: true—the flusher will attempt to copy the metric name using memcpy operations beyond the allocated heap buffer boundaries. This leads to a heap write overflow, which can cause immediate denial-of-service (process crash) or potential remote code execution (RCE). This vulnerability is fixed in 1.35.13, 1.36.9, 1.37.5, and 1.38.3.
CVE-2026-11834 2 Tp-link, Tp Link 7 Archer C20 V5, Archer C20 V6, Archer Mr200 V07 and 4 more 2026-06-26 N/A
A command injection vulnerability has been identified in the DHCP option processing logic in multiple TP-Link router models, due to insufficient validation of externally supplied DHCP option data. An adjacent attacker may exploit this vulnerability by supplying crafted DHCP responses, potentially resulting in unauthorized command execution during device initialization or provisioning workflows. This typically occurs when the device is in a factory-default or unconfigured state. Successful exploitation may allow an adjacent, unauthenticated attacker to execute arbitrary commands with elevated privileges, potentially leading to full compromise of the affected device and unauthorized administrative control.
CVE-2026-46602 1 Golang 1 Image 2026-06-26 7.5 High
The TIFF decoder does not set a limit on the size of tiles in tiled images, permitting a malicious or corrupt image containing a very large tile to cause unbounded memory consumption.
CVE-2026-55892 1 Vim 1 Vim 2026-06-26 5.5 Medium
Vim is an open source, command line text editor. Prior to 9.2.0662, the dump_prefixes() function in src/spell.c walks a spell-file prefix trie iteratively with a depth counter while dumping the prefixes that apply to a word. The counter is bounded only by the trie structure itself; it is never checked against the size of the fixed MAXWLEN-element stack arrays it indexes (prefix[], arridx[], curi[]). A crafted .spl file, loaded when the user dumps the word list, can drive the descent arbitrarily deep, so the function writes past the end of those arrays. This is a stack out-of-bounds write that corrupts the call frame and crashes the editor. This vulnerability is fixed in 9.2.0662.
CVE-2026-40711 1 Dell 1 Container Storage Modules 2026-06-26 8 High
Dell Dell Container Storage Modules, version(s) csi-powerstore v2.16.0, csi-unity v2.16.0, csi-powerflex v2.16.0, csi-powermax v2.16.0, contain(s) an Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability. A high privileged attacker with remote access could potentially exploit this vulnerability, leading to Command execution.
CVE-2026-57453 1 Vim 1 Vim 2026-06-26 6.5 Medium
Vim is an open source, command line text editor. From 9.1.1784 until 9.2.0678, when the bundled zip plugin autoload/zip.vim falls back to PowerShell to browse, read, extract, update or delete entries in a zip archive, it builds the PowerShell command by inserting archive entry names that are quoted only for the shell, not for PowerShell. A crafted entry name can break out of the intended string context and cause PowerShell to execute arbitrary commands with the privileges of the user running Vim, triggered by opening, viewing or extracting the archive. This vulnerability is fixed in 9.2.0678.
CVE-2026-9717 1 Schneider-electric 2 Powerlogic P7, Powerlogic P7 Firmware 2026-06-26 7.2 High
CWE-78 Neutralization of Special Elements used in an OS Command ('OS Command Injection') vulnerability exists that could allow unauthorized execution of commands with elevated privileges, impacting system integrity, confidentiality, and availability when a privileged authenticated user interacts with a vulnerable network-exposed service.
CVE-2026-52992 1 Linux 1 Linux Kernel 2026-06-26 7.8 High
In the Linux kernel, the following vulnerability has been resolved: fs/adfs: validate nzones in adfs_validate_bblk() Reject ADFS disc records with a zero zone count during boot block validation, before the disc record is used. When nzones is 0, adfs_read_map() passes it to kmalloc_array(0, ...) which returns ZERO_SIZE_PTR, and adfs_map_layout() then writes to dm[-1], causing an out-of-bounds write before the allocated buffer. adfs_validate_dr0() already rejects nzones != 1 for old-format images. Add the equivalent check to adfs_validate_bblk() for new-format images so that a crafted image with nzones == 0 is rejected at probe time. Found by syzkaller.
CVE-2026-53136 1 Linux 1 Linux Kernel 2026-06-26 7.8 High
In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: Clamp VBIOS HDMI retimer register count to array size [Why & How] The VBIOS integrated info tables (v1_11 and v2_1) contain HdmiRegNum and Hdmi6GRegNum fields that are used as loop bounds when copying retimer I2C register settings into fixed-size arrays (dp*_ext_hdmi_reg_settings[9] and dp*_ext_hdmi_6g_reg_settings[3]). These u8 fields are not validated before use, so a malformed VBIOS can specify values up to 255, causing an out-of-bounds heap write during driver probe. Clamp each register count to the destination array size using min_t() before the copy loops, in both get_integrated_info_v11() and get_integrated_info_v2_1(). (cherry picked from commit 5a7f0ef90195940c54b0f5bb85b87da55f038c69)
CVE-2026-53195 1 Linux 1 Linux Kernel 2026-06-26 7.8 High
In the Linux kernel, the following vulnerability has been resolved: USB: serial: io_ti: fix heap overflow in build_i2c_fw_hdr() build_i2c_fw_hdr() allocates a fixed-size buffer of (16*1024 - 512) + sizeof(struct ti_i2c_firmware_rec) bytes, then copies le16_to_cpu(img_header->Length) bytes into it without validating that Length fits within the available space after the firmware record header. img_header->Length is a __le16 from the firmware file and can be up to 65535. check_fw_sanity() validates the total firmware size but not img_header->Length specifically. Fix by rejecting images where img_header->Length exceeds the available destination space.
CVE-2026-55693 1 Vim 1 Vim 2026-06-26 7.8 High
Vim is an open source, command line text editor. Prior to 9.2.0653, the tree_count_words() function in src/spellfile.c fills in the word-count fields of a spell-file word trie by walking it iteratively with a depth counter. The counter is bounded only by the trie structure itself; it is never checked against the size of the fixed MAXWLEN-element stack arrays it indexes (arridx[], curi[], wordcount[]). A crafted .spl/.sug file pair, loaded when the user invokes spell suggestion, can drive the descent arbitrarily deep, so the function writes past the end of those arrays. This is a stack out-of-bounds write that corrupts the call frame and crashes the editor. This vulnerability is fixed in 9.2.0653.
CVE-2026-55958 1 Wolfssl 1 Wolfssl 2026-06-26 7.5 High
Out-of-bounds write in the Renesas TSIP TLS 1.3 transcript buffer. In tsip_StoreMessage() the capacity check guarding the fixed message bag (MSGBAG_SIZE) sets an error code but fails to return, so execution falls through to an XMEMCPY that writes past the end of the buffer once the accumulated TLS 1.3 handshake transcript exceeds MSGBAG_SIZE (8 KB), corrupting adjacent heap state and potentially causing a remote denial of service crash. The bag is sized to hold a normal handshake, so this is reached only by an unusually large but valid certificate chain, or by a malicious or man-in-the-middle server sending an oversized handshake message to a client that does not strictly verify the chain. This only affects builds using the Renesas TSIP TLS port (WOLFSSL_RENESAS_TSIP_TLS) as a TLS 1.3 client on Renesas MCUs with TSIP hardware enabled, and is rated High within those builds. All other configurations are unaffected.
CVE-2026-6681 1 Wolfssl 1 Wolfssl 2026-06-26 5.3 Medium
The PKCS#7 decode path ignores the caller-supplied output buffer size (outputSz), allowing decoded content to be written past the bounds of the provided buffer. This affects wolfSSL 5.9.0 and earlier and was fixed in the 5.9.1 release.
CVE-2026-6679 1 Wolfssl 1 Wolfssl 2026-06-26 7.5 High
A heap buffer overflow could occur in the DTLS 1.3 ACK serialization path before the connecting peer is authenticated. The buffer overflow was due to an integer truncation when computing the length of the ACK record-number list, causing an undersized buffer to be allocated and then overrun. This affects builds using DTLS 1.3 and wolfSSL version 5.9.0 and earlier. A fix was added to the 5.9.1 release.
CVE-2026-8797 1 Nec 1 Expressupdate Agent For Windows 2026-06-26 N/A
An access control deficiency vulnerability exists in ExpressUpdate Agent for Windows. If a malicious user gains access to the product, arbitrary code could be executed with SYSTEM privileges.
CVE-2026-6325 1 Wolfssl 1 Wolfssl 2026-06-26 7.5 High
Out-of-bounds write in SetSuitesHashSigAlgo when processing an oversized signature algorithms list, allowing a write past the bounds of the destination buffer.
