CVE-2026-64160: Linux Kernel

Critical severity, CVSS 9.8. EPSS: 0.6% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: netfs: Fix potential for tearing in ->remote_i_size and ->zero_point Fix potential tearing in using ->remote_i_size and ->zero_point by copying i_size_read() and i_size_write() and using the same seqcount as for i_size. We need to make sure that netfslib and the filesystems that use it always hold i_lock whilst updating any of the sizes to prevent i_size_seqcount from getting corrupted.

Affected products

• Linux Linux Kernel: from 5.18, before 7.0.11 (fixed in 7.0.11); version 7.1 only
