Advisory Updated Date: 2023-07-19 21:51 Pacific
A use-after-free flaw was found in the Netfilter subsystem of the Linux kernel when processing named and anonymous sets in batch requests, which can lead to performing arbitrary reads and writes in kernel memory. This flaw allows a local user with CAP_NET_ADMIN capability to crash or potentially escalate their privileges on the system. (CVE-2023-3117)
Linux Kernel nftables Out-Of-Bounds Read/Write Vulnerability; nft_byteorder poorly handled vm register contents when CAP_NET_ADMIN is in any user or network namespace (CVE-2023-35001)
Affected Packages:
kernel
Issue Correction:
