CVE-2021-39698 [HIGH] CWE-416 kernel: use-after-free in the file polling implementation
kernel: use-after-free in the file polling implementation
In aio_poll_complete_work of aio.c, there is a possible memory corruption due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-185125206References: Upstream kernel
A vulnerability was found in the Linux kernel’s file polling implementation in kernel/sched/wait.c., which leads to a use-after-free problem. This flaw allows a local user to cause a denial of service (memory corruption or crash) or privilege escalation.
Statement: There was no shipped kernel version that was seen affected by this problem.
Mitigation: Mitigation for this issue is either not available
