EUVDB-ID: #VU25813
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2020-9383
CWE-ID:
CWE-125 - Out-of-bounds read
Exploit availability: No
DescriptionThe vulnerability allows a local user to gain access to potentially sensitive information.
The vulnerability exists due to a boundary condition within the set_fdc() function in drivers/block/floppy.c file in Linux kernel due to the FDC index is not checked for errors before assigning it. A local user can use a specially crafted application to trigger out-of-bounds read error and read contents of memory on the system.

EUVDB-ID: #VU25814
Risk: Low
CVSSv3.1:
CVE-ID: CVE-2020-2732
CWE-ID:
CWE-200 - Information Exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to potentially sensitive information.
The vulnerability exists due to incomplete implementation of vmx_check_intercept on Intel processors in KVM in Linux kernel, which leads to I/O or MSR interception bitmaps are not checked. A remote attacker with access to guest operating system (e.g. L2 guest) can trick the L0 hypervisor into accessing sensitive information on the L1 hypervisor.
