CVE-2025-38519
|
| Sažetak |
In the Linux kernel, the following vulnerability has been resolved:
mm/damon: fix divide by zero in damon_get_intervals_score()
The current implementation allows having zero size regions with no special
reasons, but damon_get_intervals_score() gets crashed by divide by zero
when the region size is zero.
[ 29.403950] Oops: divide error: 0000 [#1] SMP NOPTI
This patch fixes the bug, but does not disallow zero size regions to keep
the backward compatibility since disallowing zero size regions might be a
breaking change for some users.
In addition, the same crash can happen when intervals_goal.access_bp is
zero so this should be fixed in stable trees as well. |
