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

Description The issue is related to the Linux kernel's bpf functionality, where uninit memory usages were reported during map lookup and delete operations. The problem arises from the "void *key" passed to the helper, allowing uninit stack memory access for bpf programs with the right privileges. A patch has been applied to mark the stack as initialized using kmsan unpoison memory(), addressing syzbot reports on the uninit "void *key" argument.

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