high Tenable Cloud Security Plugin ID 461139

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - In the Linux kernel, the following vulnerability has been resolved: fbcon: Make sure modelist not set on
 unregistered console It looks like attempting to write to the "store_modes" sysfs node will run afoul of
 unregistered consoles: UBSAN: array-index-out-of-bounds in drivers/video/fbdev/core/fbcon.c:122:28 index
 -1 is out of range for type 'fb_info *[32]' ... fbcon_info_from_console+0x192/0x1a0
 drivers/video/fbdev/core/fbcon.c:122 fbcon_new_modelist+0xbf/0x2d0 drivers/video/fbdev/core/fbcon.c:3048
 fb_new_modelist+0x328/0x440 drivers/video/fbdev/core/fbmem.c:673 store_modes+0x1c9/0x3e0
 drivers/video/fbdev/core/fbsysfs.c:113 dev_attr_store+0x55/0x80 drivers/base/core.c:2439 static struct
 fb_info *fbcon_registered_fb[FB_MAX]; ... static signed char con2fb_map[MAX_NR_CONSOLES]; ... static
 struct fb_info *fbcon_info_from_console(int console) ... return fbcon_registered_fb[con2fb_map[console]];
 If con2fb_map contains a -1 things go wrong here. Instead, return NULL, as callers of
 fbcon_info_from_console() are trying to compare against existing "info" pointers, so error handling should
 kick in correctly. (CVE-2025-38198)

Solution

Update the linux library and its related packages to version 6.1.147-1 or later.
