CVSS 3.1
5.5 mediumCVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:HCVE-2026-43123
Medium (5.5) in linux linux kernel. EPSS 0.1% chance of exploitation in the next 30 days.
In the Linux kernel, the following vulnerability has been resolved:
fbcon: check return value of con2fb_acquire_newinfo()
If fbcon_open() fails when called from con2fb_acquire_newinfo() then
info->fbcon_par pointer remains NULL which is later dereferenced.
Add check for return value of the function con2fb_acquire_newinfo() to
avoid it.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
