In the Linux kernel, the following vulnerability has been resolved: erofs: fix memory leak of LZMA global compressed deduplication When stressing microLZMA EROFS images with the new global compressed deduplication feature enabled (`-Ededupe`), I found some short-lived temporary pages weren't properly released, which could slowly cause unexpected OOMs hours later.
