CVE-2025-37963

Full vulnerability record from the local CVENow database.

Description

In the Linux kernel, the following vulnerability has been resolved: arm64: bpf: Only mitigate cBPF programs loaded by unprivileged users Support for eBPF programs loaded by unprivileged users is typically disabled. This means only cBPF programs need to be mitigated for BHB. In addition, only mitigate cBPF programs that were loaded by an unprivileged user. Privileged users can also load the same program via eBPF, making the mitigation pointless.

Además, solo se deben mitigar los programas cBPF cargados por un usuario sin privilegios.
