The vulnerability of the fbcon_do_set_font() function in the drivers/video/fbdev/core/fbcon.c driver for kernel-based frame buffer devices in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the fbcondosetfont function in the drivers/video/fbdev/core/fbcon.c driver for kernel-based graphics buffer devices in the Linux operating system is related to improper memory release. Exploiting this vulnerability could allow an attacker to compromise the confidentiality,...

The vulnerability of the fbcon_set_font() function in the drivers/video/fbdev/core/fbcon.c driver code of the Linux kernel’s frame buffer device driver allows a attacker to cause a system failure.

The vulnerability of the fbconsetfont function in the drivers/video/fbdev/core/fbcon.c driver for kernel-based graphics buffer devices in the Linux operating system is related to integer overflow or cyclic shift vulnerabilities. Exploiting this vulnerability could allow an attacker to cause a...

CVE-2022-50404 fbdev: fbcon: release buffer when fbcon_do_set_font() failed

In the Linux kernel, the following vulnerability has been resolved: fbdev: fbcon: release buffer when fbcondosetfont failed syzbot is reporting memory leak at fbcondosetfont 1, for commit a5a923038d70 "fbdev: fbcon: Properly revert changes when vcresize failed" missed that the buffer might be new...

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 a failure to free a buffer when the fbcondosetfont function fails, which could lead to a memory leak...

kernel: fbcon: shift-out-of-bounds in fbcon_set_font()

A flaw was found in the Framebuffer Console fbcon in the Linux Kernel. When providing a font-width and font-height greater than 32 to the fbconsetfont, since there are no checks in place, a shift-out-of-bounds occurs, leading to undefined behavior and possible denial of service...

The vulnerability of the fbcon_set_font() function in the drivers/video/fbdev/core/fbcon.c file of the Linux kernel allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the fbconsetfont function in the drivers/video/fbdev/core/fbcon.c file of the Linux kernel is related to integer overflow due to the lack of control over valid boundaries. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and...
