CVE-2026-46087
Description
A flaw was found in the Linux kernel's Data Access MONitor (DAMON) subsystem. When the damon_start() function fails during the damon_stat_start() operation, the system does not properly release the allocated memory context. This oversight leads to a memory leak, where previously allocated memory becomes permanently unreachable. Over time, this can result in resource exhaustion, potentially impacting system stability and performance.

Technical Impact: DoS: Resource Consumption (Other); DoS: Resource Consumption (Memory); DoS: Resource Consumption (CPU)
An attacker that can influence the allocation of resources that are not properly released could deplete the available resource pool and prevent all other processes from accessing the same type of resource. Frequently-affected resources include memory, CPU, disk space, power or battery, etc.
