Name of the Vulnerable Software and Affected Versions Linux kernel (affected versions not specified)

Description The issue is related to a memory leak in the erofs component of the Linux kernel, specifically with the LZMA global compressed deduplication feature enabled. When stressing microLZMA EROFS images, short-lived temporary pages are not properly released, which could slowly cause unexpected out-of-memory (OOM) errors hours later.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
