kernel security update
安全等级: High
公告ID: KylinSec-SA-2024-1242
发布日期: 2024年1月19日
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)
