CVE-2022-47946Source: Mitre Source: NIST CVE.ORG Print: PDF
Certain versions of Linux Kernel from Linux contain the following vulnerability:
An issue was discovered in the Linux kernel 5.10.x before 5.10.155. A use-after-free in io_sqpoll_wait_sq in fs/io_uring.c allows an attacker to crash the kernel, resulting in denial of service. finish_wait can be skipped. An attack can occur in some situations by forking a process and then quickly terminating it. NOTE: later kernel versions, such as the 5.15 longterm series, substantially changed the implementation of io_sqpoll_wait_sq.
- CVE-2022-47946 has been assigned by [email protected] to track the vulnerability - currently rated as MEDIUM severity.
CVSS3 Score: 5.5 - MEDIUM
