| Type | Privilege escalation |
| Description | An issue has been discovered in the Linux kernel up to version 5.11.12 that can be abused by unprivileged local users to escalate privileges. The issue is with how BPF JIT compilers for some architectures compute branch displacements when generating machine code. This can be abused to craft anomalous machine code and execute it in the Kernel mode, where the control flow is hijacked to execute unsafe code. |
