Description
In the Linux kernel, the following vulnerability has been resolved: scsi: hpsa: Fix possible memory leak in hpsa_init_one() The hpda_alloc_ctlr_info() allocates h and its field reply_map. However, in hpsa_init_one(), if alloc_percpu() failed, the hpsa_init_one() jumps to clean1 directly, which frees h and leaks the h->reply_map. Fix by calling hpda_free_ctlr_info() to release h->replay_map and h instead free h directly.

Executive Summary

This vulnerability is a possible memory leak in the Linux kernel's hpsa driver. Specifically, in the function hpsa_init_one(), if the alloc_percpu() call fails, the code jumps to a cleanup section that frees some allocated memory (h) but neglects to free a related field (h->reply_map), causing a memory leak. The fix involves properly freeing both h->reply_map and h to prevent the leak.

Impact Analysis

The impact of this vulnerability is a potential memory leak in the Linux kernel's hpsa driver. Over time, this could lead to increased memory usage and possibly degrade system performance or stability if the leak occurs repeatedly.
