NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel package and not the kernel package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

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.
