Descripción
*** Pendiente de traducción *** 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.
Impacto
