kernel security update
安全等级: High
公告ID: KylinSec-SA-2023-2339
发布日期: 2023年12月29日
关联CVE: CVE-2023-6546
The Linux Kernel, the operating system core itself.
Security Fix(es):
A race condition was found in the GSM 0710 tty multiplexor in the Linux kernel. This issue occurs when two threads execute the GSMIOC_SETCONF ioctl on the same tty file descriptor with the gsm line discipline enabled, and can lead to a use-after-free problem on a struct gsm_dlci while restarting the gsm mux. This could allow a local unprivileged user to escalate their privileges on the system.(CVE-2023-6546)
