Veracode Vulnerability DatabaseVERACODE:23903Denial Of Service (DoS)
EPSS
Percentile
90.6%
The kernel vulnerable to denial of service (DoS). The Parallels Virtuozzo Containers team reported the RHSA-2009:1243 update introduced two flaws in the routing implementation. If an attacker was able to cause a large enough number of collisions in the routing hash table (via specially-crafted packets) for the emergency route flush to trigger, a deadlock could occur. Secondly, if the kernel routing cache was disabled, an uninitialized pointer would be left behind after a route lookup, leading to a kernel panic.
