CVE-2026-43240

A flaw was found in the Linux kernel's x86/kexec component. When a second-stage kernel is booted with a memory-limiting command, the Integrity Measurement Architecture IMA kexec buffer may be located outside the accessible memory range. This can lead to a kernel panic, effectively causing a Denia...

CVE-2026-43129

A flaw was found in the Linux kernel's Integrity Measurement Architecture IMA subsystem. When a second-stage kernel is booted via kexec with a memory-limiting command line, the IMA measurement buffer from the previous kernel may fall outside the new kernel's addressable memory. This out-of-bounds...

CVE-2026-43240

CVE-2026-43240 concerns the Linux kernel (x86/kexec) where a second-stage kernel booted with a memory-limiting parameter (mem=…) may place the IMA kexec buffer outside the accessible RAM, causing a kernel panic. The vulnerability arises from a missing range validation for the carried IMA measurem...
