In the Linux kernel, the following vulnerability has been resolved: scsi: target: core: Fix integer overflow in UNMAP bounds check sbc_execute_unmap() checks LBA + range does not exceed the device capacity, but does not guard against LBA + range wrapping around on 64-bit overflow. Add an overflow check matching the pattern already used for WRITE_SAME in the same file.

CVE-2026-1160148.1 ALT37.1%
——11open62541 1.5.0 before 1.5.7 contains an integer overflow in UA_DataType_fromStructureDescription() that wraps the 16-bit memSize field for large custom structure definitions. A malicious OPC UA server can supply DataType definitions via UA_Client_getRemoteDataTypes(), causing decodeBinaryStructure() to overflow the heap, crashing clients or enabling code execution.1dCVE-2026-1155057.6 ALT10.7%
——3libsmb2 before 6.3 contains integer overflow vulnerabilities in the DCE/RPC NDR decoder in lib/dcerpc.c that allow heap out-of-bounds reads and writes. A malicious SMB server or machine-in-the-middle on unsigned connections can send crafted NetrShareEnum replies with wrapping actual_count or max_count values when clients call smb2_share_enum_async(), corrupting heap memory.2dCVE-2026-1153876.2 MED1.4%
——0Wasmtime before 36.0.16, 37.0.0 before 48.0.3, and 49.0.0 before 49.0.1 contains a denial of service vulnerability in wasmtime-wasi that allows guest WASI programs to panic the host via overflowing filesystem timestamps. Attackers can pass atim or mtim values whose sub-second field overflows the seconds field to path_filestat_set_times, fd_filestat_set_times, set-times, or set-times-at, crashing the host.3dCVE-2026-1146455.2 MED5.8%
——2A 32-bit integer wraparound in the MongoDB C Driver's Windows-only Kerberos/SSPI authentication code can cause an undersized heap buffer to be allocated when an excessively long credential value is supplied in the client's connection configuration. A party able to control that client-side configuration, in conjunction with the affected authentication mechanism, can cause the driver to write outside the bounds of the allocated buffer. This may result in corruption of client process memory and denial of service of the client application. The issue affects only client builds compiled with the Windows-native authentication backend.2dCVE-2026-103634—14.7%
——4Out-of-bounds read and write in the Count-Min sketch deserialization of Apache DataSketches C++ (repo: datasketches-cpp).
count_min_sketch::deserialize() did not include the preamble in its input size check, so a truncated sketch could cause a read of up to 16 bytes past the end of the input. In addition, the table size was computed from the serialized number of buckets and number of hash functions in 32-bit arithmetic. A crafted sketch could make it wrap to zero, so that the sketch deserialized with an empty table, and later updates and estimate queries read and wrote outside the heap allocation. This can corrupt heap memory, causing a crash and potentially enabling further exploitation.
This issue affects Apache DataSketches C++: from 4.1.0 before 5.3.0. Only applications that deserialize Count-Min sketches from untrusted sources are affected.
Users are recommended to upgrade to version 5.3.0, which fixes this issue.3dCVE-2026-11026410.0 CRÍ62.6%
——19An issue has been discovered in GitLab CE/EE affecting all versions from 7.0 before 18.11.13, 19.0 before 19.0.10, 19.1 before 19.1.9, 19.2 before 19.2.9, 19.3 before 19.3.6, 19.4 before 19.4.3, and 19.5 before 19.5.1 that, under certain conditions, could have allowed an unauthenticated user to execute arbitrary code on the GitLab server due to integer overflow when compiling a specially crafted regular expression.3d
