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 attr_off in
UpdateResidentValue against data_off In do_action()'s UpdateResidentValue case (fslog.c:3307),
lrh->attr_off and lrh->redo_len come from the on-disk LRH. When they satisfy aoff + dlen <
attr->res.data_off, the assignment attr->res.data_size = cpu_to_le32(aoff + dlen - data_off); underflows
to ~4 GiB (e.g. 0xFFFFFFF9 when aoff=0x10, dlen=1, data_off=0x18). Subsequent code that reads
attr->res.data_size to walk the resident attribute payload would then read up to 4 GiB past the 1024-byte
MFT record allocation. The existing mi_enum_attr() defense in fs/ntfs3/record.c:287 catches the corrupted
data_size on the next attribute walk and fails the mount, but only on the path that walks all attributes.
A read site that picks an attribute by name and reads its data_size without re-validating is not covered.
Validate aoff against data_off and asize at the source. Reproduced under UML+KASAN on mainline
8d90b09e6741 via pr_warn-only probe: with aoff=0x10 and data_off=0x18, the post-assignment data_size is
0xfffffff9 (mount then fails at -22 from mi_enum_attr). [[email protected]: clang-
formatted the changes] (CVE-2026-72195)

Solution

Update the sys-kernel/cchost-kernel-6_12 library and its related packages to version 19216.655.6 or later.
