| CVE-2026-102639 | 1 Mobilitydb | 1 Mobilitydb | 2026-10-02 | 6.5 Medium |
| MobilityDB version 1.3.0 and earlier contains an out-of-bounds read vulnerability in the MEOS binary and library WKB deserialization logic that allows unprivileged database users to crash the PostgreSQL backend process by supplying a crafted WKB payload with a negative length field. The negative length value wraps to a large unsigned size_t due to missing signed validation, bypasses an overflow-unsafe pointer arithmetic bounds check in wkb_parse_state_check(), and causes memcpy() in text_from_wkb_state() to operate with a corrupted unbounded length, resulting in a remote denial-of-service condition affecting all sessions on the PostgreSQL instance. | ||||
| CVE-2026-77219 | 1 Gnu | 1 Emacs | 2026-10-01 | 7.1 High |
| GNU Emacs before 31.0.91 contains an integer overflow in the PBM/PPM/PGM image loader that allows an attacker to leak heap memory contents by supplying a crafted image with large dimensions and an elevated max color index. The image loader multiplies image dimensions and channel count using signed integer arithmetic; for sufficiently large values, the result wraps to a negative number, bypassing the bounds check and causing the pixel reader to access heap memory past the end of the allocated buffer. The over-read contents are interpreted as pixel color values and rendered on screen. | ||||

| CVE-2026-103222 | 1 Blosc | 1 C-blosc2 | 2026-09-30 | 5.6 Medium |
| A vulnerability was determined in Blosc C-Blosc2 up to 3.3.2. This impacts the function blosclz_decompress of the file blosc/blosclz.c of the component blosclz Decompression. Executing a manipulation can lead to integer overflow. The attack may be launched remotely. A high complexity level is associated with this attack. The exploitability is said to be difficult. Upgrading to version 3.3.3 will fix this issue. This patch is called fe2964d114d97847f56570a0ab2be2c57ccbeedc. The affected component should be upgraded. | ||||

| CVE-2026-46655 | 1 Virtio-win | 1 Kvm-guest-drivers-windows | 2026-09-30 | 7.8 High |
| virtio-win provides Windows paravirtualized drivers for QEMU and KVM. From mm210 until mm320, the Viosock driver permits a low-privilege local process to submit an IOCTL_SELECT request with attacker-controlled VIRTIO_VSOCK_SELECT.Fdss[*].fd_count values that overflow the 32-bit sum used by VIOSockSelect for bounds checking. The wrapped sum can pass the FD_SETSIZE check even though an individual descriptor count is much larger than the expected limit. VIOSockSelectCopyFds then iterates using the unchecked count and writes beyond the allocated pPkt->Fds array in the NonPagedPool kernel heap. Successful exploitation can corrupt kernel memory and enable privilege escalation in a Windows guest running the driver. This issue is fixed in mm320. | ||||
| CVE-2026-74221 | 2 Denx, U-boot | 2 U-boot, U-boot | 2026-09-30 | 8.2 High |
| U-Boot before 2026.10-rc5 contains a buffer overflow in nfs_readlink_reply() function in net/nfs-common.c when processing NFS server responses. A malicious NFS server can send crafted READLINK replies with negative or oversized symlink length values to corrupt memory and crash the bootloader. | ||||

| CVE-2026-74765 | 1 Perl | 1 Net::idn::punycode | 2026-09-29 | 6.5 Medium |
| Net::IDN::Punycode versions before 2.590 for Perl allow an out-of-bounds read via integer overflow of the delta accumulator in encode_punycode. The XS backend keeps the punycode delta, and the digit index derived from it, in a signed int. The accumulation `delta += (m-n) * (h+1)` has no overflow check, so a large enough code point wraps the delta and the digit index leaves the range of the 36-entry digit table. The bound before the final table access tests only for an index above 36, so a negative index passes it, as does 36 itself. Perl strings hold code points beyond the Unicode range, and one such code point overflows the accumulation on its own. Valid input wraps it as well, for example 1927 ASCII letters followed by U+10FFFF. The conversion functions encode a label before they check its length, so a long label reaches the encoder through the documented API. Only the XS backend is affected. Encoding an attacker-supplied string copies a byte from outside the digit table into the encoded result or crashes the process. | ||||

| CVE-2026-88376 | 1 Axiomatic | 1 Bento4 | 2026-09-27 | 7.5 High |
| Bento4 1.6.0.0 contains an integer underflow vulnerability in AP4_AvccAtom::Create() and AP4_HvccAtom::Create(). A specially crafted MP4 file containing an avcC or hvcC atom with a declared size smaller than the atom header size can cause the payload-size calculation to wrap to a large unsigned value. The resulting invalid buffer allocation and copy operations can cause application termination, leading to denial of service. | ||||
| CVE-2026-88372 | 1 Libsndfile Project | 1 Libsndfile | 2026-09-27 | 7.5 High |
| libsndfile 1.2.2 contains an integer overflow vulnerability in mat4_read_header() when parsing crafted MAT4 (MATLAB v4) files. | ||||
| CVE-2026-93395 | 1 Mongodb | 1 C Driver | 2026-09-25 | 5.3 Medium |
| A missing lower-bound validation in the bson_new_from_buffer() function of libbson allows an integer underflow when processing BSON data with a zero-length prefix. The function reads a 32-bit document length from the input buffer but does not verify that the value is at least 5 (the minimum valid BSON document size) before using it in an array index calculation. When the length field is zero, the expression used to check the document's null terminator wraps to UINT32_MAX, causing a heap out-of-bounds read that crashes the process. An unauthorized party who can supply crafted BSON input to an application using this API can cause a denial of service. | ||||
