CLEAR_GLOBAL leaks both the find reference and the reference previously stashed in v3d->global_perfmon by the SET_GLOBAL ioctl that configured it. 3. Destroying a perfmon that is the current global perfmon leaks the reference stashed by the SET_GLOBAL ioctl. Release each of these references explicitly. The Linux kernel CVE team has assigned CVE-2026-53141 to this issue. Affected and fixed versions =========================== Issue introduced in 6.14 with commit c6eabbab359c156669e10d5dec3e71e80ff09bd2 and fixed in 6.18.36 with commit 3e1947573140a57119294f0bff39ee18d93f23e1 Issue introduced in 6.14 with commit c6eabbab359c156669e10d5dec3e71e80ff09bd2 and fixed in 7.0.13 with commit ed2eaf3b7b1820b690e4b896d344e00027526a25 Issue introduced in 6.14 with commit c6eabbab359c156669e10d5dec3e71e80ff09bd2 and fixed in 7.1 with commit 6bf7e2affc6e62da7add393d7f352d4040f5bc27 Please see https://www.kernel.org for a full list of currently supported kernel versions by the kernel community. Unaffected versions might change over time as fixes are backported to older supported kernel versions. The official CVE entry at https://cve.org/CVERecord/?id=CVE-2026-53141 will be updated if fixes are backported, please check that for the most up to date information about this issue. Affected files ============== The file(s) affected by this issue are: drivers/gpu/drm/v3d/v3d_perfmon.c Mitigation ========== The Linux kernel CVE team recommends that you update to the latest stable kernel version for this, and many other bugfixes. Individual changes are never tested alone, but rather are part of a larger kernel release. Cherry-picking individual commits is not recommended or supported by the Linux kernel community at all. If however, updating to the latest release is impossible, the individual changes to resolve this issue can be found at these commits: https://git.kernel.org/stable/c/3e1947573140a57119294f0bff39ee18d93f23e1 https://git.kernel.org/stable/c/ed2eaf3b7b1820b690e4b896d344e00027526a25 https://git.kernel.org/stable/c/6bf7e2affc6e62da7add393d7f352d4040f5bc27
