CVE-2026-43206

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

Description An out-of-bounds write exists in the kfd event page set() function. The function uses memset to write KFD SIGNAL EVENT LIMIT * 8 bytes without verifying the buffer size parameter. This allows unprivileged userspace to trigger an out-of-bounds kernel memory write by providing a small buffer, which could lead to privilege escalation.

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