CVE-2026-53282

The CVE-2026-53282 issue affects the Linux kernel’s x86/kexec purgatory code used by kexec-tools. The root cause was the purgatory path looking above the top of the stack to locate a return address for a kjump even in non-kjump kexec, which could trigger a fault/crash. A commit fixed the actual k...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Fixed the issue where the PF driver crashed during kexec kernel booting. During a kexec reboot, the hardware is not power-cycle, so the AF state from the old kernel can persist into the new kernel. When the AF and P...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: powerpc/kexec: Enable SMT before waking offline CPUs. If SMT is disabled or a partial SMT state is enabled, when a new kernel image is loaded for kexec, the following warning is observed upon reboot: kexec: Waking offline cpu 228...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: The imagetkexecbuffer function does not check whether the ima-kexec-buffer of the previous kernel lies outside the addressable memory range. This can lead to a kernel panic if the new kernel is booted with the mem=X argument, and...
