CVE-2022-50646 Details
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.
A memory leak vulnerability has been identified in the Linux kernel's SCSI HPSA driver. The issue arises in the 'hpsa_init_one()' function, where the 'hpda_alloc_ctlr_info()' function allocates a controller structure and its 'reply_map' field. If 'alloc_percpu()' fails, 'hpsa_init_one()' skips to a cleanup section that frees the controller structure but not the 'reply_map', leading to a memory leak. This vulnerability affects several versions of the Linux kernel.
The vulnerability has been fixed in the Linux kernel. Users should upgrade to a version that includes the fix.
