## Overview

In the Linux kernel, the following vulnerability has been resolved:

proc: use the same treatment to check proc_lseek as ones for proc_read_iter et.al

Check pde->proc_ops->proc_lseek directly may cause UAF in rmmod scenario. 
It's a gap in proc_reg_open() after commit 654b33ada4ab("proc: fix UAF in
proc_get_inode()").  Followed by AI Viro's suggestion, fix it in same
manner.

## Affected

- `linux_kernel >= 6.0, < 6.1.148`
- `linux_kernel >= 6.2, < 6.6.102`
- `linux_kernel >= 6.7, < 6.12.42`
- `linux_kernel >= 6.13, < 6.15.10`
- `linux_kernel >= 6.16, < 6.16.1`
- `debian_linux = 11.0`

## Remediation

Upgrade past the affected range:

- `linux_kernel 6.16.1`
