Vulnerability from fkie_nvd - Published: 2026-09-03 13:06 - Updated: 2026-10-30 13:20
Severity
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/amdkfd: Add bounds check for CRAT subtype length
The CRAT parser validates that the subtype header fits within the image,
but does not verify that the advertised subtype length fits. A malformed
CRAT table with an oversized length field causes out-of-bounds reads when
kfd_parse_subtype() casts the header to specific subtype structures.
Add validation that sub_type_hdr + length does not exceed the image
boundary before parsing the subtype contents.
(cherry picked from commit 48e1d1e6e8798aef0312e68d8e586021b5b3cf4d)
