Detailsinfo

A vulnerability was found in Linux Kernel up to 2.6.36 (Operating System). It has been classified as critical. This affects the function mlx4_register_vlan/mlx4_register_mac of the file drivers/net/mlx4/port.c. The manipulation as part of a Variable leads to a memory corruption vulnerability. CWE is classifying the issue as CWE-119. The product performs operations on a memory buffer, but it can read from or write to a memory location that is outside of the intended boundary of the buffer. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

In the Linux kernel before 2.6.37, an out of bounds array access happened 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.

The weakness was disclosed 07/27/2019. This vulnerability is uniquely identified as CVE-2010-5332 since 07/27/2019. It is possible to initiate the attack remotely.
