This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation. ### From the Ubuntu Security Team It was discovered that an integer overflow existed in the Binder implementation of the Linux kernel, leading to a buffer overflow. A local attacker could use this to escalate privileges. ## Status Show unmaintained releases | Package | Ubuntu Release | Status | | --- | --- | --- | | linux | 20.04 LTS focal | Not affected | |
