Rocky Linux 8 [CIQ] Security Update: bpftool / bpftool-debuginfo / kernel / kernel-abi-stablelists / etc Multiple Vulnerabilities (crlsa-2026_72468)

The Rocky Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the CIQ crlsa-202672468 advisory. kernel: fbcon: Set fbdisplayi-mode to NULL when the mode is released CVE-2025-40323 kernel: ext4: fix e4b bitmap inconsistency reports CVE-2026-45942...

kernel: fbcon: Set fb_display[i]->mode to NULL when the mode is released

A use-after-free vulnerability was identified in the Linux kernel framebuffer console fbcon subsystem. During framebuffer unregistration, the kernel freed the memory for a display mode but did not clear the corresponding fbdisplayi-mode pointer. Subsequent framebuffer ioctl operations could then...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: fbcon: The old font data is always restored in fbcondosetfont. The commit a5a923038d70 fbdev: fbcon: Properly revert changes when vcresize fails started restoring old font data upon failure of vcresize. However, this only applies...

Astra Linux – Vulnerability in Linux

A buffer overflow attack in fbcon in the Linux kernel before version 5.9.7 could be exploited by local attackers to read privileged information or potentially cause the kernel to crash. This issue is identified as CID-3c4e0dff2095. This vulnerability arises because the KDFONTOPCOPY function in...
