Description

In the Linux kernel, the following vulnerability has been resolved:

crypto: tegra - Add missing CRYPTO_ALG_ASYNC

The tegra crypto driver failed to set the CRYPTO_ALG_ASYNC on its
asynchronous algorithms, causing the crypto API to select them for users
that request only synchronous algorithms. This causes crashes (at
least). Fix this by adding the flag like what the other drivers do.
Also remove the unnecessary CRYPTO_ALG_TYPE_* flags, since those just
get ignored and overridden by the registration function anyway.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.

Weaknesses

Reachable Assertion

The product contains an assert() or similar statement that can be triggered by an attacker, which leads to an application exit or other behavior that is more severe than necessary. Learn more on MITRE.
