CVE-2026-68165

A flaw was found in the Linux kernel's Data Access MONitor DAMON core logic. A local user could exploit this by providing invalid, zero-length memory region ranges through DAMON's application programming interface API callers. This improper input validation can lead to a divide-by-zero error,...

EUVD-2026-55551

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-2026-68165

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...

EUVD-2026-55550

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-2026-68164

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...

CVE-2026-64458

A flaw was found in the Linux kernel's Data Access MONitor DAMON subsystem. A local user with write permissions to the system file system sysfs can exploit this vulnerability by configuring extreme zero or excessively high monitoring intervals. This improper handling of interval values can lead t...

CVE-2026-64239

A flaw was found in the Linux kernel's Data Access Monitor DAMON system file system sysfs component. A local user could exploit a timing issue during the refresh of DAMON region directories, leading to a use-after-free vulnerability. This could result in memory corruption, potentially causing...
