The vulnerability of the do_register_framebuffer() function in the fbdev/core/fbmem.c file of the Linux kernel allows a attacker to compromise the integrity and accessibility of the protected information.

The vulnerability of the doregisterframebuffer function in the fbdev/core/fbmem.c file of the Linux kernel relates to writing beyond the buffer boundaries. Exploiting this vulnerability allows an attacker to compromise the integrity and accessibility of the protected information...

SUSE CVE-2025-38312

In the Linux kernel, the following vulnerability has been resolved: fbdev: core: fbcvt: avoid division by 0 in fbcvthperiod In fbfindmodecvt, iff mode-refresh somehow happens to be 0x80000000, cvt.frefresh will become 0 when multiplying it by 2 due to overflow. It's then passed to fbcvthperiod,...

CVE-2025-38312 fbdev: core: fbcvt: avoid division by 0 in fb_cvt_hperiod()

In the Linux kernel, the following vulnerability has been resolved: fbdev: core: fbcvt: avoid division by 0 in fbcvthperiod In fbfindmodecvt, iff mode-refresh somehow happens to be 0x80000000, cvt.frefresh will become 0 when multiplying it by 2 due to overflow. It's then passed to fbcvthperiod,...

CVE-2025-38312

CVE-2025-38312 concerns the Linux kernel fbdev path: fbcvt. In fb_find_mode_cvt(), if mode->refresh equals 0x80000000, cvt.f_refresh overflows when doubled, and is subsequently used as a divider in fb_cvt_hperiod(), causing a division by zero and potential kernel oops. The vulnerability is res...

PT-2025-29032

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The Linux kernel contains a flaw within the fbdev core and fbcvt functionality that could lead to a kernel oops due to a division by zero error. This occurs in the fb cvt hperiod...

CVE-2021-47338: Use After Free

In the Linux kernel, the following vulnerability has been resolved: fbmem: Do not delete the mode that is still in use The execution of fbdeletevideomode is not based on the result of the previous fbconmodedeleted. As a result, the mode is directly deleted, regardless of whether it is still in us...

Linux kernel fbcon.c file out-of-bounds read vulnerability

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. An out-of-bounds read vulnerability exists in versions of Linux kernel prior to 6.2.12, which stems from assigning only the first vc in setcon2fbmap in...

CVE-2023-38409

An issue was discovered in setcon2fbmap in drivers/video/fbdev/core/fbcon.c in the Linux kernel before 6.2.12. Because an assignment occurs only for the first vc, the fbconregisteredfb and fbcondisplay arrays can be desynchronized in fbconmodedeleted the con2fbmap points at the old fbinfo...
