CVE-2026-76471 1 Cisco 2 Nx-os Software, Unified Computing System Manager 2026-10-11 9.8 Critical
A vulnerability in the NX-API feature of Cisco NX-OS Software could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device.  The vulnerability is due to insufficient input validation of data that is sent to the NX-API. An attacker could exploit this vulnerability by sending a crafted HTTP request to the NX-API of an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes, which could result in a reload of the device and a DoS condition.
CVE-2026-107161 2 Cyrusimap, Redhat 6 Cyrus-sasl, Enterprise Linux, Hardened Images and 3 more 2026-10-10 7.5 High
A heap-based buffer overflow flaw was found in Cyrus SASL. The add_to_challenge() function in the DIGEST-MD5 plugin computes the size of the buffer needed for a challenge/response field before DIGEST-MD5 quoting is applied, but does not recompute that size when quoting (escaping special characters) makes the value longer. The under-sized buffer is then passed to strcat(), causing a heap-based out-of-bounds write whose size depends on attacker-controlled input. A malicious or on-path DIGEST-MD5 (or HTTP Digest) server can trigger this flaw in a connecting client by supplying a crafted challenge field, such as realm or nonce, most likely resulting in a crash of the client application.
CVE-2026-96396 1 Canva 1 Affinity 2026-10-09 4.9 Medium
The Affinity by Canva application for macOS before 3.3.1 (October 2026 release) did not safely calculate the size of an image buffer when generating QuickLook thumbnails and previews of Affinity document files, leading to an integer overflow and a heap-based buffer overflow. A threat actor could craft an Affinity document that, when displayed or previewed by a user in Finder, could corrupt heap memory and cause the thumbnail or preview extension to crash.
CVE-2026-46569 1 Tuxera 1 Ntfs-3g 2026-10-09 7.7 High
In NTFS-3G before 2026.7.7, a heap buffer overflow exists in ntfs_ib_copy_tail(), in libntfs-3g/index.c, that allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image. The overflow is triggered by extending a directory, e.g., by creating a file.
CVE-2022-2849 2 Fedoraproject, Vim 2 Fedora, Vim 2026-10-09 7.8 High
Heap-based Buffer Overflow in GitHub repository vim/vim prior to 9.0.0220.
CVE-2026-105842 2 Lrzsz Project, Uwe Ohse 2 Lrzsz, Lrzsz 2026-10-09 6.4 Medium
lrzsz before 0.13.0 contains a heap-based buffer overflow vulnerability in procheader() of the lrz receive utility when copying overlong sender-supplied filenames into Pathname. Malicious ZMODEM senders can supply filenames up to 8192 bytes, overflowing the buffer via sprintf() in pipe mode or strcpy() to corrupt heap memory and crash lrz.
CVE-2026-106177 1 Hp Inc 4 Hp Sure Click Enterprise, Hp Wolf Pro Security, Hp Wolf Pro Security Edition and 1 more 2026-10-09 6.4 Medium
A kernel buffer overflow vulnerability in HP Sure Click versions prior to 4.4.33 may allow local privilege escalation or arbitrary code execution. HP has released version 4.4.33 to address this vulnerability.
CVE-2026-106547 1 Hdfgroup 1 Hdf5 2026-10-09 7.8 High
A heap-based buffer overflow in H5VM_array_fill() in src/H5VM.c in HDF5 before 2.2.0 lets a remote attacker cause an application crash and possibly execute arbitrary code with a crafted HDF5 file. When a dataset's unallocated chunks are read, H5D__fill_init() fills the fill-value buffer from datatype and dataspace metadata in the file. If that metadata is inconsistent with the buffer's allocated size, the write goes past the end of the buffer. The attacker can control the content written through the fill value stored in the file.
CVE-2026-103010 1 Progressive Robot 1 Hmailserver 2026-10-09 7.8 High
Heap-based buffer overflow in the legacy Blowfish decryption routine (BlowFishEncryptor::DecryptFromString) in Progressive Robot hMailServer 6.0.0 through 6.3.3 on Windows allows a local interactive user with no hMailServer credentials to write bytes of their choosing past the end of a 255-byte heap buffer in the hMailServer service process, which runs as LocalSystem by default. The user does this by passing a long hexadecimal string to the COM method Utilities.BlowfishDecrypt, which checked no authentication. The routine converted hexadecimal input of any length into a fixed 255-byte buffer before decrypting it in place. The result is a denial of service (service crash), and possibly code execution with the privileges of the service account.
CVE-2026-15028 1 Redhat 4 Cost Management On Premise, Enterprise Linux, Hummingbird and 1 more 2026-10-09 3.9 Low
A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive. The issue occurs during the parsing of a PAX extended header containing a malformed SUN.holesdata sparse-file attribute. Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system.
CVE-2022-0213 2 Debian, Vim 2 Debian Linux, Vim 2026-10-08 6.6 Medium

CVE-2020-35493 4 Broadcom, Fedoraproject, Gnu and 1 more 9 Brocade Fabric Operating System Firmware, Fedora, Binutils and 6 more 2026-10-08 5.5 Medium
A flaw exists in binutils in bfd/pef.c. An attacker who is able to submit a crafted PEF file to be parsed by objdump could cause a heap buffer overflow -> out-of-bounds read that could lead to an impact to application availability. This flaw affects binutils versions prior to 2.34.
