What is CVE-2026-23260?

A memory leak vulnerability exists in the Linux kernel's regcache_maple_write() function, which is responsible for managing resources when merging adjacent ranges. If the memory allocation function mas_store_gfp() fails, the system fails to free the allocated memory for a new entry, leading to unnecessary memory usage and potential system instability over time. Proper handling of memory allocation failures is critical to prevent resource exhaustion and maintain optimal system performance.
