CVE-2020-7459

CVE-2020-7459 affects FreeBSD 12.x and 11.x UDB network drivers (smsc(4), muge(4), cdceem(4)). The issue is a missing length validation in multiple USB network drivers that allows a malicious USB device to write beyond the end of an allocated network packet buffer, potentially enabling kernel or ...

Denial Of Service (DoS)

kernel is vulnerable to denial of service DoS. The vulnerability exists as a flaw was found in the way the Linux kernel handled VLAN 0 frames with the priority tag set. When using certain network drivers, an attacker on the local network could use this flaw to cause a denial of service...

Privilege Escalation

kernel is vulnerable to privilege escalation. The vulnerability exists as multiple NULL pointer dereferences were found in various Linux kernel network drivers. These drivers were missing checks for terminal validity, which could allow privilege escalation...

Memory corruption

In the Linux kernel before 5.3.11, there is a use-after-free bug that can be caused by a malicious USB device in the drivers/net/can/usb/mcbausb.c driver, aka CID-4d6636498c41...

Null pointer dereference

drivers/net/wireless/intel/iwlwifi/pcie/trans.c in the Linux kernel 5.2.14 does not check the allocworkqueue return value, leading to a NULL pointer dereference...

CVE-2019-12819

An issue was discovered in the Linux kernel before 5.0. The function mdiobusregister in drivers/net/phy/mdiobus.c calls putdevice, which will trigger a fixedmdiobusinit use-after-free. This will cause a denial of service...
