Vulnerability from fkie_nvd - Published: 2024-08-21 07:15 - Updated: 2024-09-13 13:29
Severity ?
5.5 (Medium) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: nommu: fix memory leak in do_mmap() error path The preallocation of the maple tree nodes may leak if the error path to "error_just_free" is taken. Fix this by moving the freeing of the maple tree nodes to a shared location for all error paths.
