CVE-2024-46673 Information

Description

In the Linux kernel the following vulnerability has been resolved:

scsi: aacraid: Fix double-free on probe failure

aac_probe_one() calls hardware-specific init functions through the aac_driver_ident::init pointer all of which eventually call down to aac_init_adapter().

If aac_init_adapter() fails after allocating memory for aac_dev::queues it frees the memory but does not clear that member.

After the hardware-specific init function returns an error aac_probe_one() goes down an error path that frees the memory pointed to by aac_dev::queues resulting.in a double-free.
