Hanjie Lin 27a1861d28 RAVENPLAT 2381:OSS vulnerability found in [boot.img]:[linux_kernel] (CVE-2018-6555) Risk:[] [1/1]

PD#OTT-5671

[Problem]
The irda_setsockopt function in net/irda/af_irda.c and later in
drivers/staging/irda/net/af_irda.c in the Linux kernel before 4.17
allows local users to cause a denial of service (ias_object
		use-after-free and system crash) or possibly have unspecified other
impact via an AF_IRDA socket.

[Solution]
The irda_setsockopt() function conditionally allocates memory for a new
self->ias_object or, in some cases, reuses the existing
self->ias_object. Existing objects were incorrectly reinserted into the
LM_IAS database which corrupted the doubly linked list used for the
hashbin implementation of the LM_IAS database. When combined with a
memory leak in irda_bind(), this issue could be leveraged to create a
use-after-free vulnerability in the hashbin list. This patch fixes the
issue by only inserting newly allocated objects into the database.

[Test]
