Description SMASH SMASH 2024-01-23 16:47:48 UTC 
An issue was discovered in ksmbd in the Linux kernel before 6.6.10. smb2_get_data_area_len in fs/smb/server/smb2misc.c can cause an smb_strndup_from_utf16 out-of-bounds access because the relationship between Name data and CreateContexts data is mishandled.
