CVE-2026-72135: In the Linux kernel, the following vulnerability has been resolved: tpm: Make the TPM character devices non-seekable T

A vulnerability in Linux kernel TPM (Trusted Platform Module, a security chip) character devices allowed attackers to read or write memory outside intended bounds by using positional I/O operations (pread/pwrite) with large offsets, potentially causing crashes or information leaks. The kernel was leaving these devices seekable (able to jump to arbitrary positions) when they should only support sequential access.
