CVE-2026-93395: Integer Underflow (Wrap or Wraparound)

A missing lower-bound validation in the bsonnewfrombuffer 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...

CVE-2026-89028

MikroTik RouterOS before 7.24 contains a heap memory corruption vulnerability in the userspace SMB daemon that allows remote attackers to corrupt adjacent heap memory by supplying a crafted uniPwdLen value in the SMB1 SessionSetupAndX handler. An attacker can send a malformed SMB1 request with a...

CVE-2026-89028

MikroTik RouterOS versions before 7.24 are affected by a heap memory corruption vulnerability in the userspace SMB daemon. The root cause is an integer underflow triggered by a crafted uniPwdLen field in the SMB1 SessionSetupAndX handler, which causes an oversized copy length to be used when copy...
