CVE-2026-31707
Description
A flaw was found in the Linux kernel's ksmbd component. A remote attacker could exploit an integer overflow vulnerability when the system processes specially crafted daemon responses. This manipulation of data sizes can bypass internal security checks, leading to memory corruption. Such an issue could potentially allow an attacker to gain unauthorized access or cause system instability.
Understanding the Weakness (CWE)
Integrity,Availability,Confidentiality
Technical Impact: DoS: Crash, Exit, or Restart; Execute Unauthorized Code or Commands; Read Memory; Modify Memory
If the incorrect calculation is used in the context of memory allocation, then the software may create a buffer that is smaller or larger than expected. If the allocated buffer is smaller than expected, this could lead to an out-of-bounds read or write (CWE-119), possibly causing a crash, allowing arbitrary code execution, or exposing sensitive data.
