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 werent properly released, which could slowly cause
unexpected OOMs hours later.
Lets fix it now (LZ4 and DEFLATE dont have this issue.)
