CVE-2026-93099

This CVE affects the Linux kernel fs/resctrl subsystem, specifically the Resource Director Technology (RDT) filesystem. The vulnerability is a Use-After-Free (UAF) in worker threads mbm_handle_overflow() and cqm_handle_limbo() . The root cause is that these workers may be blocked waiting for cpus...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: scsi: qla2xxx: Fixed a crash that occurred when I/O abort times out. During CPU hotplug, a crash was observed with the following stack: Call Trace: qla24xxprocessresponsequeue+0x42a/0x970 qla2xxx qla2x00startnvmemq+0x3a2/0x4b0...

Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerability has been resolved: sched/scs: The task stack state is reset in bringupcpu. When a CPU is hot-plugged, the idle task on that CPU calls several layers of C code before finally leaving the kernel. When KASAN is in use, a “poisoned” shadow is left behi...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerabilities have been resolved: hrtimers: Timers queued after CPUHPAPHRTIMERSDYING are forced to be migrated away from the dying CPU to any online target. This is done to avoid delaying bandwidth timer handling tasks related to CPU hotplug progress. However,...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: “riscv”: prevents corruption of pt regs for secondary idle threads. The top of the kernel thread stack should be reserved for pt regs. However, this is not the case for the idle threads of the secondary boot harts. Their stacks...

Linux Distros Unpatched Vulnerability : CVE-2026-89460

"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - s390/cpumcf: Handle CPU hotplug via prepare/dead callbacks The command 'perf stat -e cycles -- ' crashes the kernel when CPUs are hotplug added during that run...

CVE-2026-89460

A flaw was found in the Linux kernel. A local user can trigger a kernel panic by running the perf stat command while CPUs are being hotplugged. This occurs because the system fails to properly allocate CPU event structures for newly online CPUs, leading to a null pointer dereference. Successful...

CVE-2026-89769

A flaw was found in the Linux kernel's NXP PIT Programmable Interrupt Timer clocksource driver. When the CPU hotplug setup fails after an interrupt request IRQ has been successfully registered, the error handling does not properly free the IRQ. This oversight results in a leaked IRQ line and a...
