CVE-2015-5707

Publication date 3 August 2015

Last updated 24 July 2024

Ubuntu priority

Medium

Why this priority?

Integer overflow in the sg_start_req function in drivers/scsi/sg.c in the Linux kernel 2.6.x through 4.x before 4.1 allows local users to cause a denial of service or possibly have unspecified other impact via a large iov_count value in a write request.

From the Ubuntu Security Team

It was discovered that an integer overflow error existed in the SCSI generic (sg) driver in the Linux kernel. A local attacker with write permission to a SCSI generic device could use this to cause a denial of service (system crash) or potentially escalate their privileges.

kamal

As per BenH's notes, the fdc81f45 fix requires import_iovec() from bc917be8 (v4.1-rc1), so set the 'break' SHA for that to bc917be8.
