Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

Integer overflow in the _ctl_do_mpt_command function in drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel 2.6.38 and earlier might allow local users to gain privileges or cause a denial of service (memory corruption) via an ioctl call specifying a crafted value that triggers a heap-based buffer overflow.

Mitigation

Install update from vendor's website.

Vulnerable software versions
