20     +When kptr_restrict is set to (1), kernel pointers printed using the %pK
21     +format specifier will be replaced with 0's unless the user has CAP_SYSLOG
22     +and effective user and group ids are equal to the real ids. This is
23     +because %pK checks are done at read() time rather than open() time, so
24     +if permissions are elevated between the open() and the read() (e.g via
25     +a setuid binary) then %pK will not leak kernel pointers to unprivileged
26     +users. Note, this is a temporary solution only. The correct long-term
27     +solution is to do the permission checks at open() time. Consider removing
28     +world read permissions from files that use %pK, and using dmesg_restrict
29     +to protect against uses of %pK in dmesg(8) if leaking kernel pointer
30     +values to unprivileged users is a concern.

32     +When kptr_restrict is set to (2), kernel pointers printed using
