Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from driver data not being set when vmclockptpregister fails, resulting in uninitialized data being accessed duri...

CVE-2025-21814: NULL Pointer Dereference

In the Linux kernel, the following vulnerability has been resolved: ptp: Ensure info-enable callback is always set The ioctl and sysfs handlers unconditionally call the -enable callback. Not all drivers implement that callback, leading to NULL dereferences. Example of affected drivers: ptps390.c,...

CVE-2025-21822: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ptp: vmclock: Set driver data before its usage If vmclockptpregister fails during probing, vmclockremove is called to clean up the ptp clock and misc device. It uses devgetdrvdata to access the vmclock state. However the driver...
