The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper validation of SIB type when processing a NR system Information message in Modem component. A remote attacker can pass specially crafted data to the application and perform a denial of service (DoS) attack.


10) Information disclosure (CVE-ID: CVE-2021-35080)

The vulnerability allows a local appliction to gain access to potentially sensitive information.

The vulnerability exists due to excessive data output by the application in KERNEL component. A local appliction can gain unauthorized access to sensitive information on the system.


11) Memory leak (CVE-ID: CVE-2021-35078)

The vulnerability allows a remote attacker to perform DoS attack on the target system.

The vulnerability exists due to memory leak while parsing server certificate chain in Data Modem component. A remote attacker can force the application to leak memory and perform denial of service attack.


12) Reachable Assertion (CVE-ID: CVE-2021-35073)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to improper validation of rank restriction field in Modem component. A remote attacker can pass a specially crafted data and cause a denial of service.


13) Improper Validation of Array Index (CVE-ID: CVE-2021-35072)

The vulnerability allows a local application to escalate privileges on the system.

The vulnerability exists due to a boundary error in RFA component when processing external DIAG command. A local application can trigger buffer overflow and execute arbitrary code with elevated privileges.

14) Time-of-check Time-of-use (TOCTOU) Race Condition (CVE-ID: CVE-2021-35090)

The vulnerability allows a local application to escalate privileges on the system.

The vulnerability exists due to TOC TOU race condition when updating address mappings within KERNEL component. A local appliction can send specially crafted data and execute arbitrary code with elevated privileges.
