kernel security update
安全等级: Medium
公告ID: KylinSec-SA-2023-2291
发布日期: 2023年10月20日
关联CVE: CVE-2023-39189 CVE-2023-39193
The Linux Kernel, the operating system core itself.
Security Fix(es):
A flaw was found in the Netfilter subsystem in the Linux kernel. The nfnl_osf_add_callback function did not validate the user mode controlled opt_num field. This flaw allows a local privileged (CAP_NET_ADMIN) attacker to trigger an out-of-bounds read, leading to a crash or information disclosure.(CVE-2023-39189)
