Описание
In rcu_cblist_dequeue of rcu_segcblist.c, there is a possible use-after-free due to improper locking. This could lead to local escalation of privilege in the kernel with System execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-222091980References: Upstream kernel
A use-after-free flaw was found in the Linux kernel’s io_uring (in fs/io_uring.c) when improper locking happens. This flaw allows a local user to crash or potentially escalate their privileges on the system.
Отчет
At this time, no Red Hat Enterprise Linux products ship with support for this feature. There is an outstanding feature request for io_uring to be included with Red Hat Enterprise Linux 9.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options does not meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
