Description
The vulnerability allows a local attacker to cause a denial of service.
The vulnerability exists due to an infinite loop in bond_header_parse() when parsing packet headers in a stack of two bonding devices. A local attacker can trigger packet processing in this configuration to cause a denial of service.
The issue occurs because device recursion can remain bounded to the hierarchy top, leading to repeated parsing instead of reaching the final leaf parse method.
Remediation
Install security update from vendor's repository.
