CVE-2019-19051
Published: 18 November 2019
A memory leak in the i2400m_op_rfkill_sw_toggle() function in drivers/net/wimax/i2400m/op-rfkill.c in the Linux kernel before 5.3.11 allows attackers to cause a denial of service (memory consumption), aka CID-6f3ef5c25cc7.
From the Ubuntu Security Team
It was discovered that the Intel WiMAX 2400 driver in the Linux kernel did not properly deallocate memory in certain situations. A local attacker could use this to cause a denial of service (kernel memory exhaustion).
