CVE-2022-50391
Last modified
CVE-2022-50391 is a medium-severity vulnerability rated 5.5/10 on the CVSS scale. In the Linux kernel, the following vulnerability has been resolved: mm/mempolicy: fix memory leak in set_mempolicy_home_node system call When encountering any vma in the range with policy other than MPOL_BIND or MPOL_PREFERRED_MANY, an error is returned without issuing a mpol_put on the policy just allocated with mpol_dup(). This allows arbitrary users to leak kernel memory.. EPSS estimates a 0.14% chance of exploitation in the next 30 days.
