CVE-2026-31734

CVE-2026-31734 (Linux kernel sched_ext) has been fixed. The issue was a false negative where is_bpf_migration_disabled() could be incorrect on systems without CONFIG_PREEMPT_RCU, causing migration_disabled == 1 to be treated as truly migration-disabled even for the current task. The BPF prolog no...

In the Linux kernel, the following vulnerability has been resolved: schedext: Fix isbpfmigrationdisabled false negative on non-PREEMPTRCU Since commit 8e4f0b1ebcf2 "bpf: use rcureadlockdontmigrate for trampoline.c", the BPF prolog bpfprogenter calls migratedisable only when CONFIGPREEMPTRCU is...

Linux kernel 安全漏洞

The Linux kernel is the core of the open-source operating system Linux, developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from false negatives in the migration disable check under the PREEMPTRCU configuration. This could lea...

CVE-2023-53215

CVE-2023-53215 affects the Linux kernel sched/fair component. The issue occurs when the load balancer tries to migrate a task that is migration-disabled to its current CPU, triggering a warning in set_task_cpu() during balance. The root cause is how the new_dst_cpu is selected from env->dst_gr...
