CVE-2025-70293 1 Denx 1 U-boot 2026-09-02 9.8 Critical
An issue was discovered in Denx U-Boot before 2026.04. An integer overflow vulnerability exists in function ext4fs_get_bgdtable, the size calculation can lead to under allocation and this underallocated buffer will be used in memcpy() which could lead to arbitrary code execution, a denial of service, or other unspecified impacts.
CVE-2026-84268 1 Redhat 1 Enterprise Linux 2026-09-02 8.8 High
A flaw was found in the SFTP backend in gvfs. When mounting a share and reading a file, a malicious SFTP server can cause read_reply() to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the allocated buffer size, causing the operation to write past the intended boundaries. This issue allows a malicious server to corrupt adjacent heap memory in the gvfsd-sftp process, resulting in a denial of service as the process aborts upon detecting the heap corruption or potentially allowing arbitrary code execution.
CVE-2026-75538 1 Erlang 3 Erlang/otp, Erlang\/otp, Otp 2026-09-01 N/A
An attacker that connects to an open Erlang TCP port that uses the inet driver with {packet,4} mode can use a signed overflow in an incorrect packet length calculation to overflow the receive buffer into the VM allocator area and beyond up to about 2 GB. This would easily trash the allocated block's allocator metadata footer, and the next block, if any, and most likely cause the BEAM VM to crash. Utilizing this with precision enough to achieve Remote Code Execution would be extremely unfeasible. This issue affects OTP from OTP 17.0 before OTP 27.3.4.17, from OTP 28.0 before OTP 28.5.0.6, and from OTP 29.0 before OTP 29.0.6, corresponding to erts from 6.0 before 15.2.7.13, from 16.0 before 16.4.0.6, and from 17.0 before 17.0.6. Whether OTP before OTP 17.0, corresponding to erts before 6.0, is affected is unknown.
CVE-2026-84269 1 Redhat 1 Enterprise Linux 2026-09-01 6.5 Medium
A flaw was found in the AFP backend in gvfs. When mounting a share, a malicious AFP server can cause the DSI read path to process a length that exceeds the size requested by the client. The function does not verify the server-provided length against the pre-sized reply buffer, causing the operation to access past the intended boundaries. This issue allows a malicious server to overflow a heap buffer and crash the gvfsd-afp process, resulting in a denial of service.
CVE-2026-49429 1 Freebsd 1 Freebsd 2026-09-01 7.8 High
The ZFS_IOC_USERSPACE_MANY ioctl, used by zfs-userspace(8), truncated a 64-bit output buffer size to a 32-bit integer for the kernel allocation, but used the original 64-bit size as the buffer limit when writing records. A local user with the "userused" delegated ZFS permission can trigger a kernel heap overflow via the ZFS_IOC_USERSPACE_MANY ioctl, potentially escalating privileges.
CVE-2026-49430 1 Freebsd 1 Freebsd 2026-09-01 7.8 High
The ZFS_IOC_RECV_NEW ioctl, in the heal receive path, similarly truncated a 64-bit payload size to a 32-bit integer for allocation, then used the original 64-bit size as the length for a byteswap operation. A local user with the "receive" delegated ZFS permission can trigger kernel memory corruption via ZFS_IOC_RECV_NEW by sending a crafted receive stream in heal mode.
CVE-2026-82820 2 Flvmeta, Noirotm 2 Flvmeta, Flvmeta 2026-09-01 4.3 Medium
A vulnerability was found in FLVMeta up to 1.2.2. Affected is the function amf_string_new of the file src/amf.c of the component AMF String Processing. The manipulation of the argument length results in heap-based buffer overflow. The attack can be launched remotely. The exploit has been made public and could be used. The patch is identified as f412a33b9a84c2d1a9dee145a868feddbf64879e. A patch should be applied to remediate this issue. The project maintainer doubts the security impact: "While I acknowledged the bugs and provided fixes, I have yet to see any way to exploit these alleged vulnerabilities."
CVE-2022-27666 5 Debian, Fedoraproject, Linux and 2 more 24 Debian Linux, Fedora, Linux Kernel and 21 more 2026-09-01 7.8 High
A heap buffer overflow flaw was found in IPsec ESP transformation code in net/ipv4/esp4.c and net/ipv6/esp6.c. This flaw allows a local attacker with a normal user privilege to overwrite kernel heap objects and may cause a local privilege escalation threat.
CVE-2026-80703 1 Linux 1 Linux Kernel 2026-09-01 5.5 Medium
In the Linux kernel, the following vulnerability has been resolved: drm/amdkfd: Fix missing authorization check in KFD_IOC_DBG_TRAP_DISABLE Prevent unauthorized termination of active GPU debug sessions. Previously, users with /dev/kfd access could terminate another process's debug session without proper ownership or ptrace authorization. (cherry picked from commit 4db4c5ffd5585b72622ecf6ffedf2da258ee23f5)

CVE-2026-82591 1 Assimp 1 Assimp 2026-08-31 5.3 Medium
A security vulnerability has been detected in Open Asset Import Library Assimp up to 6.0.2. The impacted element is the function MD5Importer::MakeDataUnique of the file code/AssetLib/MD5/MD5Loader.cpp. The manipulation of the argument iNewIndex leads to heap-based buffer overflow. The attack can only be performed from a local environment. The identifier of the patch is bf9dabb617c46e5133dac65cca6bff177917afcb. Applying a patch is the recommended action to fix this issue.

CVE-2026-58081 1 Freebsd 1 Freebsd 2026-08-31 9.8 Critical
Several encoding modules, including HZ, UTF-7, VIQR, and ZW, did not properly check the size of the caller-supplied output buffer before writing converted characters. An application that uses iconv(3) to convert untrusted input to or from one of the affected encodings may be vulnerable to buffer overflows if it uses one of the affected encoding modules.
