An issue was discovered in ksmbd in the Linux kernel 5.15 through 5.19 before 5.19.2. fs/ksmbd/smb2pdu.c omits a kfree call in certain smb2_handle_negotiate error conditions, aka a memory leak.
The product does not sufficiently track and release allocated memory after it has been used, making the memory unavailable for reallocation and reuse.
