Name of the Vulnerable Software and Affected Versions
Linux kernel versions prior to 5.0.6
Description
The issue is related to a NULL pointer dereference in the
drop sysctl table() function in the Linux kernel, specifically in fs/proc/proc sysctl.c, and is connected to the put links command. This could allow an attacker to gain unauthorized access to protected information.Recommendations
For Linux kernel versions prior to 5.0.6, update to version 5.0.6 or later to resolve the issue.
As a temporary workaround, consider restricting access to the
drop sysctl table() function and the put links command until a patch is available.Correção
