CVE-2026-64508

CVE-2026-64508 relates to a Linux kernel vulnerability in BPF JIT memory reuse. The issue arises when the BPF JIT allocator reuses space for new programs, potentially letting indirect jumps reuse stale branch predictions. Fix implemented: flush indirect branch predictors on JIT memory reuse via a...

CVE-2026-64439

CVE-2026-64439: In the Linux kernel, the krb5 AEAD path could free a buffer while an async AEAD worker still held a pointer, causing a use-after-free (KASAN). The fix filters out async AEAD implementations at allocation time in krb5_aead_encrypt()/krb5_aead_decrypt() and corresponding rfc3961_sim...

CVE-2026-64429

CVE-2026-64429 : In the Linux kernel, the gpio eic-sprd driver used a sleeping lock during irq startup (spin_lock_irqsave) which could be invoked from an irq_startup path, leading to a sleeping function in an invalid context on PREEMPT_RT. The fix converts the Spreadtrum EIC controller lock to a ...

CVE-2026-64374 sched/rt: Have RT_PUSH_IPI be default off for non PREEMPT_RT

In the Linux kernel, the following vulnerability has been resolved: sched/rt: Have RTPUSHIPI be default off for non PREEMPTRT RT migration is done aggressively. When a CPU schedules out a high priority RT task for a lower priority task, it will look to see if there's any RT tasks that are waiting...

CVE-2026-64374

CVE-2026-64374 concerns the Linux kernel’s RT scheduling path. The vulnerability stems from making RT_PUSH_IPI default off for non-PREEMPT_RT configurations, which could affect RT migration when high-priority RT tasks are scheduled across CPUs. The mechanism normally pulls RT tasks between CPUs u...
