Summary
In the NR RRC component, improper handling of messages received before authentication causes a data abort that can crash the affected software, resulting in a denial of service. The provided facts do not specify how an attacker reaches the bug, so no access path is stated.
Written by anthropic/claude-haiku-5.5 from the sources below. Verify against them.

What would change the score
- Would score about 55 if added to CISA KEV
- Would score about 50 if CISA's SSVC rates exploitation active
- Would score about 22 if advisories confirm default setups are exposed
