CVE-2026-64039
In the Linux kernel, the following vulnerability has been resolved:
drm/msm/snapshot: fix dumping of the unaligned regions
The snapshotting code internally aligns data segment to 16 bytes. This
works fine for DPU code (where most of the regions are aligned), but
fails for snapshotting of the DSI data (because DSI data region is
shifted by 4 bytes). Fix the code by removing length alignment and by
accurately printing last registers in the region. While reworking the
code also fix the 16x memory overallocation in
msm_disp_state_dump_regs().

CSIRTS triage
- What
- Multiple kernel flaws including NTFS file system out-of-bounds read, AMD processor floating point unit data exposure, and AMD Zen 2 operation cache isolation failure.
- Who is affected
- Systems running affected Linux kernel versions; local attackers on systems with NTFS mounted or AMD processors.
- Urgency
- Moderate to high — local attackers can gain privilege escalation and information disclosure; apply patches promptly.
- Action
- Apply kernel security updates provided by distribution maintainer.
