Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: fs/ntfs3: bound NTFS_DE view.data_off
 in UpdateRecordData{Root,Allocation} In do_action()'s UpdateRecordDataRoot (fslog.c:3489) and
 UpdateRecordDataAllocation (fslog.c:3697) cases, the memmove destination is `Add2Ptr(e,
 le16_to_cpu(e->view.data_off))`, where e->view.data_off comes from an on-disk NTFS_DE inside an INDEX_ROOT
 or INDEX_BUFFER. Neither case validates view.data_off + dlen against e->size; the existing
 check_if_index_root / check_if_alloc_index helpers walk the entry chain and validate the entry's offset,
 but not its internal view fields. The neighbouring read sites (e.g., fs/ntfs3/index.c when iterating view
 entries) check view.data_off + view.data_size <= e->size. Apply the same bound at the two memmove sites.
 Reproduced under UML+KASAN on mainline 8d90b09e6741 via pr_warn-only probe instrumentation: with
 view.data_off forced to 0xFFFC, the memmove writes 32 bytes past the end of the NTFS_DE. This is similar
 in shape to Pavitra Jha's 2026-05-02 patch "fs/ntfs3: prevent oob in case UpdateRecordDataRoot"
 (<[email protected]>) which proposes calling ntfs3_bad_de_range(); that helper
 does not exist in mainline. This patch uses inline checks. (CVE-2026-64532)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19506.299.116 or later.
