Kerentanan Missing Release of Memory after Effective Lifetime pada linux kernel. Skor CVSS 3.1 5.5 (Medium) menurut NVD.

Deskripsi (NVD)

In the Linux kernel, the following vulnerability has been resolved: ubifs: Fix memory leak in do_rename If renaming a file in an encrypted directory, function fscrypt_setup_filename allocates memory for a file name. This name is never used, and before returning to the caller the memory for it is not freed. When running kmemleak on it we see that it is registered as a leak. The report below is triggered by a simple program 'rename' that renames a file in an encrypted directory: unreferenced object 0xffff888101502840 (size 32): comm "rename", pid 9404, jiffies 4302582475 (age 435.735s) backtrace: __kmem_cache_alloc_node __kmalloc fscrypt_setup_filename do_rename ubifs_rename vfs_rename do_renameat2 To fix this we can remove the call to fscrypt_setup_filename as it's not needed.
