Detailsinfo

A vulnerability classified as critical has been found in Linux Kernel up to 6.0.9. This affects the function octep_device_setup of the component octeon_ep. The manipulation with an unknown input leads to a memory leak vulnerability. CWE is classifying the issue as CWE-401. The product does not sufficiently track and release allocated memory after it has been used, which slowly consumes remaining memory. This is going to have an impact on availability. The summary by CVE is:

In the Linux kernel, the following vulnerability has been resolved: octeon_ep: fix potential memory leak in octep_device_setup() When occur unsupported_dev and mbox init errors, it did not free oct->conf and iounmap() oct->mmio[i].hw_addr. That would trigger memory leak problem. Add kfree() for oct->conf and iounmap() for oct->mmio[i].hw_addr under unsupported_dev and mbox init errors to fix the problem.
