CVE-2026-20786
Description
A flaw was found in the Intel NPU Driver. This vulnerability, an out-of-bounds read, could allow a local attacker with low privileges to cause a denial of service (DoS). A denial of service means the system or application becomes unavailable to legitimate users. The flaw can be exploited by an unprivileged, authenticated user through local access without requiring user interaction or special knowledge. Successful exploitation primarily impacts the availability of the system, making it unresponsive or unusable.
Statement
Red Hat products are not affected by this vulnerability as they do not ship the Intel NPU Driver. Community packages in Fedora and EPEL are tracked separately.
Mitigation
No mitigation is needed for Red Hat products as they are not affected.
Understanding the Weakness (CWE)
Confidentiality
Technical Impact: Read Memory
An attacker could get secret values such as cryptographic keys, PII, memory addresses, or other information that could be used in additional attacks.
Confidentiality
Technical Impact: Bypass Protection Mechanism
Out-of-bounds memory could contain memory addresses or other information that can be used to bypass ASLR and other protection mechanisms in order to improve the reliability of exploiting a separate weakness for code execution.
Availability
Technical Impact: DoS: Crash, Exit, or Restart
An attacker could cause a segmentation fault or crash by causing memory to be read outside of the bounds of the buffer. This is especially likely when the code reads a variable amount of data and assumes that a sentinel exists to stop the read operation, such as a NUL in a string.
Other
Technical Impact: Varies by Context
The read operation could produce other undefined or unexpected results.
