CVE-2026-68165

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: validate ranges in damonsetregions DAMON core logic assumes zero length regions don't exist. However, a few DAMON API callers including DAMONSYSFS, DAMONRECLAIM and DAMONLRUSORT allow users to set empty monitoring...

CVE-2026-68164

In the Linux kernel, the following vulnerability has been resolved: mm/damon/core: disallow overlapping input ranges for damonsetregions damonsetregions assumes the input ranges are sorted by the address and don't overlap each other. Hence the assumption was initially to be explicitly validated...

CVE-2026-68165

The CVE affects the Linux kernel DAMON subsystem (mm/damon/core) where damon_set_regions() did not validate zero-length regions created by certain callers (DAMON_SYSFS, DAMON_RECLAIM, DAMON_LRU_SORT). This could trigger WARN_ONCE on CONFIG_DAMON_DEBUG_SANITY and cause a divide-by-zero in damon_me...

CVE-2026-68164

The CVE concerns the Linux kernel DAMON subsystem, specifically the function damon_set_regions() in mm/damon/core. The root cause was that input ranges were assumed to be sorted and non-overlapping, but a prior commit removed validation, allowing overlapping ranges. The consequence can be odd mon...

PT-2026-69564

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A flaw exists in the Linux kernel where the damon set regions function fails to validate that input ranges are sorted by address and do not overlap. This lack of validation can lead to...
