UBUNTU-CVE-2020-14304

A memory disclosure flaw was found in the Linux kernel's ethernet drivers, in the way it read data from the EEPROM of the device. This flaw allows a local user to read uninitialized values from the kernel memory. The highest threat from this vulnerability is to confidentiality...

PT-2020-20856

Name of the Vulnerable Software and Affected Versions macOS versions prior to 10.15.6 Description The issue involves an out-of-bounds read that can be addressed with improved input validation. A local user may be able to cause unexpected system termination or read kernel memory. Recommendations F...

CVE-2020-15137

All versions of HoRNDIS are affected by an integer overflow in the RNDIS packet parsing routines. A malicious USB device can trigger disclosure of unrelated kernel memory to userspace applications on the host, or can cause the kernel to crash. Kernel memory disclosure is especially likely on 32-b...

CVE-2020-15137 Integer overflow in HoRNDIS

All versions of HoRNDIS are affected by an integer overflow in the RNDIS packet parsing routines. A malicious USB device can trigger disclosure of unrelated kernel memory to userspace applications on the host, or can cause the kernel to crash. Kernel memory disclosure is especially likely on 32-b...

CVE-2020-15137

CVE-2020-15137 affects HoRNDIS — an integer overflow in HoRNDIS::receivePacket of the RNDIS packet parser. The vulnerability allows a malicious USB device to disclose kernel memory to userspace on the host (more likely on 32-bit kernels) or cause a kernel crash (more likely on 64-bit kernels) via...

CVE-2020-15137: Integer Overflow or Wraparound

All versions of HoRNDIS are affected by an integer overflow in the RNDIS packet parsing routines. A malicious USB device can trigger disclosure of unrelated kernel memory to userspace applications on the host, or can cause the kernel to crash. Kernel memory disclosure is especially likely on 32-b...
