Vulnerability identifier: #VU63766

CSH Severity: High

CVSS v4: 8.5 [CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N]

CVE-ID: CVE-2021-22600

CWE-ID: CWE-415

Exploitation vector: Local access

Exploit availability: The vulnerability is being exploited in the wild

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

The vulnerability exists due to a boundary error in the packet_set_ring() function in net/packet/af_packet.c. A local user can pass specially crafted data to the application, trigger double free error and escalate privileges on the system.

Note, the vulnerability is being actively exploited in the wild against Android users.
