CVE-2026-23260

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> regmap: maple: free entry on mas_store_gfp() failure<br /> <br /> regcache_maple_write() allocates a new block (&amp;#39;entry&amp;#39;) to merge<br /> adjacent ranges and then stores it with mas_store_gfp().<br /> When mas_store_gfp() fails, the new &amp;#39;entry&amp;#39; remains allocated and<br /> is never freed, leaking memory.<br /> <br /> Free &amp;#39;entry&amp;#39; on the failure path; on success continue freeing the<br /> replaced neighbor blocks (&amp;#39;lower&amp;#39;, &amp;#39;upper&amp;#39;).
