Amazon Linux 2023 Security Advisory: ALAS2023LIVEPATCH-2023-005
Advisory Released Date: 2023-06-12
Advisory Updated Date: 2023-06-13
Severity:
Important
Issue Overview:
In the Linux kernel through 6.2.7, fs/ntfs3/inode.c has an invalid kfree because it does not validate MFT flags before replaying logs. (CVE-2022-48425)
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)
