Description
In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix buffer overrun Klocwork warning: Buffer Overflow - Array Index Out of Bounds Driver uses fc_els_flogi to calculate size of buffer. The actual buffer is nested inside of fc_els_flogi which is smaller. Replace structure name to allow proper size calculation.

Executive Summary

This vulnerability is a buffer overrun (buffer overflow) in the Linux kernel's qla2xxx SCSI driver. The driver uses the fc_els_flogi structure to calculate the size of a buffer, but the actual buffer nested inside fc_els_flogi is smaller than expected. This mismatch can lead to an array index out of bounds, causing a buffer overflow. The fix involved replacing the structure name to ensure the proper size calculation of the buffer.

Impact Analysis

A buffer overflow vulnerability can potentially allow an attacker to overwrite memory, which may lead to system crashes, data corruption, or execution of arbitrary code with kernel privileges. This can compromise system stability and security.
