An update for kernel is now available for openEuler-20.03-LTS-SP3 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2023-1760 Final 1.0 1.0 2023-10-20 Initial 2023-10-20 2023-10-20 openEuler SA Tool V1.0 2023-10-20 kernel security update An update for kernel is now available for openEuler-20.03-LTS-SP3. 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) A flaw was found in the Netfilter subsystem in the Linux kernel. The sctp_mt_check did not validate the flag_count 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-2023-39193) An update for kernel is now available for openEuler-20.03-LTS-SP3. openEuler Security has rated this update as having a security impact of medium.
