A vulnerability in the irda_bind() function of the Linux Kernel could allow a local attacker to cause a denial of service (DoS) condition on a targeted system.
The vulnerability is due to improper memory operations performed by the affected software when the irda_bind() function, as defined in the net/irda/af_irda.c source code file, is used. An attacker could exploit this vulnerability by repeatedly binding an AF_IRDA socket. A successful exploit could exhaust memory resources, resulting in a DoS condition on the targeted system.
At the time this alert was first published, suggested patches were available; however, Kernel.org had not confirmed the vulnerability.
To exploit this vulnerability, the attacker must have user-level access to the targeted system. This access requirement may reduce the likelihood of a successful exploit.
