CVE-2026-64245

CVE-2026-64245 is a use-after-free vulnerability in the Linux kernel's fbdev subsystem, specifically in fb_find_mode() within modedb. When mode_option is NULL, it is assigned from mode_option_buf, and a pointer name aliases that buffer. The buffer is then freed via kfree() while name is still der...

AZL-92579 CVE-2026-63826 affecting package kernel for versions less than 6.6.144.1-2

In the Linux kernel, the following vulnerability has been resolved: fbdev: fix use-after-free in storemodes storemodes replaces a framebuffer's modelist with modes from userspace. On success it frees the old modelist with fbdestroymodelist. Two fields still point into that freed list. One pointer...

AZL-92549 CVE-2026-53403 affecting package kernel for versions less than 6.6.144.1-2

In the Linux kernel, the following vulnerability has been resolved: fbdev: Fix fbnewmodelist to prevent null-ptr-deref in fbvideomodetovar info-var, a framebuffer's current mode, is expected to have a matching entry in info-modelist. vartodisplay relies on this and treats a failed fbmatchmode as...

CVE-2026-63826

The CVE-2026-63826 issue affects the Linux kernel fbdev path, where store_modes() frees a framebuffer modelist but leaves stale pointers in fb_display[i].mode and fb_info->mode. The root cause is use-after-free reads when fbcon_mode_deleted() and show_mode() dereference these pointers after fb...

In the Linux kernel, the following vulnerability has been resolved: fbdev: fix use-after-free in storemodes storemodes replaces a framebuffer's modelist with modes from userspace. On success it frees the old modelist with fbdestroymodelist. Two fields still point into that freed list. One pointer...

CVE-2026-53403

The CVE-2026-53403 issue is a Linux kernel framebuffer (fbdev) risk fixed by correcting fb_new_modelist to preserve the current mode in info->var when the modelist is replaced. Root cause: info->var must have a matching entry in info->modelist; if store_modes() or fb_new_modelist() chang...
