CVE-2026-68424

CVE-2026-68424 affects the Linux kernel MTD virt_concat code. The root cause is a use-after-free: mtd_concat_destroy() frees item->concat, so calling mtd_virt_concat_put_mtd_devices(item->concat) can use freed memory. The fix migrates the call to mtd_virt_concat_put_mtd_devices() to occur b...

CVE-2026-68423 mtd: virt_concat: fix use-after-free in mtd_virt_concat_destroy()

In the Linux kernel, the following vulnerability has been resolved: mtd: virtconcat: fix use-after-free in mtdvirtconcatdestroy mtdconcatdestroy frees item-concat so calling mtdvirtconcatputmtddevicesitem-concat after that leads to a use-after-free. Fix it by moving mtdvirtconcatputmtddevices...

CVE-2026-68423

The vulnerability CVE-2026-68423 concerns the Linux kernel’s MTD subsystem, specifically the virt_concat code path. A use-after-free occurs in mtd_virt_concat_destroy() because mtd_concat_destroy() frees item->concat, after which mtd_virt_concat_put_mtd_devices(item->concat) may be invoked,...
