In the Linux kernel, the following vulnerability has been resolved: scsi: qla2xxx: Fix crash when I/O abort times out While performing CPU hotplug, a crash with the following stack was seen: Call Trace: qla24xxprocessresponsequeue+0x42a/0x970 qla2xxx qla2x00startnvmemq+0x3a2/0x4b0 qla2xxx...

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 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...

CVE-2026-31480

CVE-2026-31480 concerns a Linux kernel deadlock in CPU hotplug when tracing with osnoise. The vulnerability arises from a lock-ordering issue: a mutex_lock on interface_lock is taken while osnoise_sleep() and subsequent actions hold cpu hotplug state, followed by cpus_read_lock(), which can cause...
