Description
This security bulletin contains information about 1 security vulnerability.
1) Out-of-bounds read (CVE-ID: CVE-2010-5332)
The vulnerability allows a local user to perform denial of service (DoS) attack.
The vulnerability exists due to a boundary condition in drivers/net/mlx4/port.c when searching for a free entry in either mlx4_register_vlan() or mlx4_register_mac(), and there is no free entry. The loop terminates without updating the local variable free thus causing out of array bounds access. A local user can perform denial of service attack.
