Linux kernel 缓冲区错误漏洞

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 openEuler-22.03-LTS, which originates from an out-of-bounds kernel write to memory when a font with malicious data is set vi...

OESA-2022-1748 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: Using the ioctl function to modify the vcfont.height value through PIOFONT can cause the KASAN: vmalloc-out-of-bounds in sysimageblit problem. Requires tty group permissions to access the device file /dev/tty1.CVE-2021-33656...

CVE-2022-2153

A flaw was found in the Linux kernel’s KVM when attempting to set a SynIC IRQ. This issue makes it possible for a misbehaving VMM to write to SYNIC/STIMER MSRs, causing a NULL pointer dereference. This flaw allows an unprivileged local attacker on the host to issue specific ioctl calls, causing a...
