Advisory Release Date: 2023-05-25 17:42 Pacific
Advisory Updated Date: 2023-06-05 17:57 Pacific
Severity:
Important
Issue Overview:
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 of service. (CVE-2022-4379)
In the Linux kernel through 6.3.1, a use-after-free in Netfilter nf_tables when processing batch requests can be abused to perform arbitrary read and write operations on kernel memory. Unprivileged local users can obtain root privileges. This occurs because anonymous sets are mishandled. (CVE-2023-32233)
