nDPI 5.1.0 contains a memory access issue in the DNS dissector and serializer deserialization code. Specially crafted network input can cause byte-buffer addresses at odd offsets to be cast to uint16_t or wider integer pointers and directly dereferenced without alignment checks. This results in undefined behavior and can cause process termination in UBSan-instrumented builds or on strict-alignment architectures, leading to denial of service.

CVE-2026-93925—38.6%
——12Stack-based buffer overflow, Incorrect bitwise shift of integer vulnerability in Apache Thrift C++ THeaderProtocol.
This issue affects Apache Thrift: before 0.25.0.
Users are recommended to upgrade to version 0.25.0, which fixes the issue.18dCVE-2026-50726.5 MED23.5%
——7A bitwise shift vulnerability in Zephyr's PTP subsystem allows a remote attacker to cause undefined behavior and potential system crashes. An attacker sends a crafted PTP_MSG_MANAGEMENT message to set an unvalidated negative log_announce_interval value in the port's data set. When a subsequent PTP_MSG_ANNOUNCE message is processed, port_timer_set_timeout_random computes a timeout as NSEC_PER_SEC >> -log_seconds; if the attacker-supplied value is sufficiently negative (e.g., -127), the shift amount exceeds the 64-bit integer width, triggering undefined behavior in C. This can cause a system crash via a compiler-generated illegal instruction trap on some architectures, or produce an erroneous zero timeout leading to resource starvation loops or other logical errors.5dCVE-2026-44266.5 MED46.8%
——14A flaw was found in libarchive. An Undefined Behavior vulnerability exists in the zisofs decompression logic, caused by improper validation of a field (`pz_log2_bs`) read from ISO9660 Rock Ridge extensions. A remote attacker can exploit this by supplying a specially crafted ISO file. This can lead to incorrect memory allocation and potential application crashes, resulting in a denial-of-service (DoS) condition.49dCVE-2023-528107.8 HIG16.8%
——5In the Linux kernel, the following vulnerability has been resolved:
fs/jfs: Add check for negative db_l2nbperpage
l2nbperpage is log2(number of blks per page), and the minimum legal
value should be 0, not negative.
In the case of l2nbperpage being negative, an error will occur
when subsequently used as shift exponent.
Syzbot reported this bug:
UBSAN: shift-out-of-bounds in fs/jfs/jfs_dmap.c:799:12
shift exponent -16777216 is negative78dCVE-2016-98428.8 HIG92.4%
——28The inflateMark function in inflate.c in zlib 1.2.8 might allow context-dependent attackers to have unspecified impact via vectors involving left shifts of negative integers.98d
