Description
This security bulletin contains information about 1 security vulnerability.
1) Use after free (CVE-ID: CVE-2019-10125)
The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.
An issue was discovered in aio_poll() in fs/aio.c in the Linux kernel through 5.0.4. A file may be released by aio_poll_wake() if an expected event is triggered immediately (e.g., by the close of a pair of pipes) after the return of vfs_poll(), and this will cause a use-after-free.
Remediation
Install update from vendor's website.
