Additional information
NVDhttps://nvd.nist.gov/vuln/detail/CVE-2022-4379
CWEhttps://cwe.mitre.org/data/definitions/416.html

A use-after-free vulnerability was found in __nfs42_ssc_open() in fs/nfs/nfs4file.c in the Linux kernel. This flaw allows an attacker to conduct a remote denial

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
