Description OSIDB Bzimport 2025-12-09 01:02:19 UTC 
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.
