Status: ModifiedMedium (4.9)—
Severity4.9Medium · CVSS 3.1
Exploitation probability0.69 %higher than 52% of CVEs
Active exploitationNonot in the CISA catalog
Public exploitNot knownno public code found

In Bluetooth, there is a possible out of bounds read due to a use after free. This could lead to remote information disclosure with heap information written to the log with System execution privileges needed. User interaction is not needed for exploitation.
