CVE-2020-25704 [MEDIUM] Linux kernel vulnerabilities
Title: Linux kernel vulnerabilities
Summary: Several security issues were fixed in the Linux kernel.
It was discovered that the console keyboard driver in the Linux kernel
contained a race condition. A local attacker could use this to expose
sensitive information (kernel memory). (CVE-2020-25656)
Minh Yuan discovered that the tty driver in the Linux kernel contained race
conditions when handling fonts. A local attacker could possibly use this to
expose sensitive information (kernel memory). (CVE-2020-25668)
Bodong Zhao discovered a use-after-free in the Sun keyboard driver
implementation in the Linux kernel. A local attacker could use this to
cause a denial of service or possibly execute arbitrary code.

A use after free in the Linux kernel infiniband hfi1 driver in versions prior to 5.10-rc6 was found in the way user calls Ioctl after open dev file and fork. A local user could use this flaw to crash the system.
A flaw use after free in the Linux kernel infiniband hfi1 driver was found in the way user calls Ioctl after open dev file and fork. A local user could use this flaw to crash the system.
Statement: This flaw is rated as having a Moderate impact because the issue can only be triggered by an authorized local user with access to a system with specific hardware present.
Mitigation: To mitigate this issue, prevent the module hfi1 from being loaded. Please see https://access.redhat.com/solutions/41278 for i
