CVE-2025-68741

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> scsi: qla2xxx: Fix improper freeing of purex item<br /> <br /> In qla2xxx_process_purls_iocb(), an item is allocated via<br /> qla27xx_copy_multiple_pkt(), which internally calls<br /> qla24xx_alloc_purex_item().<br /> <br /> The qla24xx_alloc_purex_item() function may return a pre-allocated item<br /> from a per-adapter pool for small allocations, instead of dynamically<br /> allocating memory with kzalloc().<br /> <br /> An error handling path in qla2xxx_process_purls_iocb() incorrectly uses<br /> kfree() to release the item. If the item was from the pre-allocated<br /> pool, calling kfree() on it is a bug that can lead to memory corruption.<br /> <br /> Fix this by using the correct deallocation function,<br /> qla24xx_free_purex_item(), which properly handles both dynamically<br /> allocated and pre-allocated items.
