Veracode Vulnerability DatabaseVERACODE:24897Privilege Escalation

Percentile
5.1%
kernel is vulnerable to privilege escalation. The vulnerability exists as it was found that the perf tool, a part of the Linux kernelâs Performance Events implementation, could load its configuration file from the current working directory. If a local user with access to the perf tool were tricked into running perf in a directory that contains a specially-crafted configuration file, it could cause perf to overwrite arbitrary files and directories accessible to that user.
