Linux · Linux Kernel · CVE-2025-37807
**Name of the Vulnerable Software and Affected Versions**
Linux kernel (affected versions not specified)
**Description**
A memory leak issue has been identified in the Linux kernel, specifically in the bpf (Berkeley Packet Filter) module. The issue arises due to the non-8-byte aligned storage of percpu pointers in the htab elem set ptr() function. This causes the kmemleak detector to fail to identify the memory leak, resulting in an unreferenced object. The problem can be reproduced using the bpf selftest by enabling the CONFIG DEBUG KMEMLEAK config, adding a getchar() before skel destroy in test hash map(), and running the test progs.
**Recommendations**
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
