CVE-2026-99107

In the Linux kernel, the following vulnerability has been resolved: ntfs: fix incorrect MFT record pointer passed to ntfsattrrecordresize ntfsnewattrflags() passes the wrong MFT record to ntfsattrrecordresize(). When the attribute is in an extent record, ctx->mrec points to the extent but the function receives the base record pointer m, causing incorrect size calculations in memmove. Fix by passing ctx->mrec (the actual MFT record containing the attribute) instead of m (the base MFT record) to ntfsattrrecordresize().
