Comment 2 Petr Mladek 2022-12-15 15:46:26 UTC

The bug was introduced by the commit ae2e1aad3e48 ("drivers/misc/lkdtm/bugs.c: add arithmetic overflow and array bounds checks") back in v5.7-rc1.

It means that affected are SLE15-SP4 and SLE15-SP5 products.

The fix is trivial. I am going to backport it.

Comment 3 Petr Mladek 2022-12-16 14:18:11 UTC

I have added the fix into SLE15-SP4 branch. The SLE15-SP5 branch is going
to get it from there.

Reassigning back to the security team for further tracking.
