An update for kernel is now available for openEuler-20.03-LTS-SP1 Security Advisory openeuler-security@openeuler.org openEuler security committee openEuler-SA-2024-1083 Final 1.0 1.0 2024-01-19 Initial 2024-01-19 2024-01-19 openEuler SA Tool V1.0 2024-01-19 kernel security update An update for kernel is now available for openEuler-20.03-LTS-SP1. The Linux Kernel, the operating system core itself. Security Fix(es): A flaw was found in the Bluetooth subsystem of the Linux kernel. A race condition between the bt_sock_recvmsg() and bt_sock_ioctl() functions could lead to a use-after-free on a socket buffer ("skb"). This flaw allows a local user to cause a denial of service condition or potential code execution.(CVE-2023-51779) An issue was discovered in the Linux kernel before 6.6.8. do_vcc_ioctl in net/atm/ioctl.c has a use-after-free because of a vcc_recvmsg race condition.(CVE-2023-51780) An issue was discovered in the Linux kernel before 6.6.8. atalk_ioctl in net/appletalk/ddp.c has a use-after-free because of an atalk_recvmsg race condition.(CVE-2023-51781) An update for kernel is now available for openEuler-20.03-LTS-SP1. openEuler Security has rated this update as having a security impact of high. A Common Vunlnerability Scoring System(CVSS)base score,which gives a detailed severity rating, is available for each vulnerability from the CVElink(s) in the References section.
