| CVE-2026-56788 | 2 Rtklib, Tomojitakasu | 2 Rtklib, Rtklib | 2026-06-27 | 4.4 Medium |
| RTKLIB through 2.4.3 contains an out-of-bounds read vulnerability in getcodepri function when processing unrecognized RINEX observation codes, allowing attackers to trigger denial of service. Crafted RINEX files with unknown observation types cause negative array indexing into the codepris table, resulting in reliable crashes and potential memory disclosure of adjacent global data. | ||||
| CVE-2026-46601 | 1 Golang | 1 Image | 2026-06-27 | 7.5 High |
| The webp decoder can panic when processing a VP8 chunk with dimensions that do not match the canvas size. | ||||
| CVE-2026-54341 | 1 Dragonflydb | 1 Dragonfly | 2026-06-26 | 7.5 High |
| Dragonfly is an in-memory data store built for modern application workloads. Prior to 1.39.0, a crafted RESTORE payload triggers an out-of-bounds read in DragonflyDB's listpack collection loaders, crashing the entire server process (SIGSEGV). Because DragonflyDB requires no authentication by default and RESTORE is a normal keyspace command, an unauthenticated remote attacker can crash the server with a single ~24-byte command — a remote, repeatable denial of service. This vulnerability is fixed in 1.39.0. | ||||
| 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-2026-30040 | 1 Faststone | 1 Faststone Image Viewer | 2026-06-26 | 6.5 Medium |
| A heap overflow in the FSViewer.exe process of FastStone Image Viewer v8.3 allows attackers to cause a execute arbitrary code in the context of the current process via supplying a crafted JPEG 2000 (JP2) file. | ||||
| CVE-2026-45257 | 1 Freebsd | 1 Freebsd | 2026-06-26 | 7.8 High |
| The KTLS receive path decrypted each record in place, assuming that the mbufs holding received data were anonymous and safe to modify. This assumption does not hold for data placed on a socket by sendfile(2), which can reference file-backed memory directly through non-anonymous M_EXTPG pages or EXT_SFBUF mbufs. When the sender transmits such data over a loopback connection without enabling KTLS on the transmit side, the file-backed mbufs reach the receiver's decryption path unchanged. Decrypting a record in place then overwrites the backing file's page cache instead of a private copy of the data. An unprivileged local user who can read a file can overwrite its contents with data of their choosing by sending the file over a loopback connection on which they have enabled KTLS receive. The write modifies the page cache directly, so it bypasses file flags such as schg and is written back to disk. By overwriting a setuid binary or other trusted file, a local user can escalate privileges, potentially gaining full control of the affected system. | ||||
| CVE-2026-57454 | 1 Vim | 1 Vim | 2026-06-26 | 6.1 Medium |
| Vim is an open source, command line text editor. From 9.2.0320 until 9.2.0679, a crafted undo or swap file can store a virtual-text property whose offset and length point outside the line's property data. When Vim restores or displays such a line it converts the offset into a pointer and reads the virtual text without bounds checking, causing an out-of-bounds read that can crash Vim or disclose adjacent heap memory. This vulnerability is fixed in 9.2.0679. | ||||
| CVE-2026-57880 | 1 Geovision Inc. | 1 Gv-lpclpc2011 2211 | 2026-06-26 | 9.8 Critical |
| An unauthenticated stack-based buffer overflow vulnerability exists in ssvr in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when parsing RTSP Digest authentication fields. A remote attacker may exploit this vulnerability by sending a crafted RTSP request containing overly long authentication data, resulting in memory corruption, denial of service, or potentially arbitrary code execution. | ||||
| CVE-2026-57881 | 1 Geovision Inc. | 1 Gv-lpclpc2011 2211 | 2026-06-26 | 9.8 Critical |
| An unauthenticated stack-based buffer overflow vulnerability exists in vlsvr in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient length validation when processing remote login data. A remote attacker may exploit this vulnerability by sending crafted login data with overly long input, resulting in memory corruption, denial of service, or potentially arbitrary code execution. | ||||
| CVE-2026-57878 | 1 Geovision Inc. | 1 Gv-lpclpc2011 2211 | 2026-06-26 | 9.8 Critical |
| An unauthenticated stack-based buffer overflow vulnerability exists in thttpd in GeoVision GV-LPC2011 and GV-LPC2211 V1.12 and earlier. The vulnerability is caused by insufficient bounds checking when processing web request parameters in a specific request path. A remote attacker may exploit this vulnerability by sending a crafted HTTP request with overly long input, resulting in memory corruption, denial of service, or potentially arbitrary code execution. | ||||
| 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-2026-12340 | 1 Wolfssl | 1 Wolfssl | 2026-06-26 | 7.5 High |
| Out-of-bounds heap read during SM2/SM3 certificate signature verification. When parsing a certificate with an SM3wSM2 signature, the Subject Key Identifier computation reads the trailing 65 bytes of the public key without checking that the key is at least that long. A public key shorter than 65 bytes results in an out-of-bounds heap read, leading to a potential crash (denial of service); there is no out-of-bounds write. Note this only affects builds with SM2 support (--enable-sm2 or --enable-all). | ||||
| 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-2025-26240 | 1 Jazzcore | 1 Python-pdfkit | 2026-06-26 | 8.4 High |
