CVE-2026-64075

CVE-2026-64075 is a use-after-free vulnerability in the Linux kernel's fprobe subsystem (part of KProbes tracing). The root cause is that commit 4346ba1604093 rewrote fprobe on the function-graph tracer to use an RCU hash list but forgot to wait for an RCU grace period in unregister_fprobe(), all...

CVE-2026-64073

Summary of CVE-2026-64073 (Linux kernel): A use-after-free in irq_work_single() on PREEMPT_RT was fixed. On PREEMPT_RT, non-HARD irq_work runs in per-CPU kthreads via run_irq_workd(), and irq_work_sync() uses rcuwait() to wait for BUSY==0. After irq_work_single() clears BUSY with atomic_cmpxchg()...

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Make RX SKB per-port The SKB used to assemble packets from fragments in gmacrx is static local, but the Gemini has two ethernet ports, meaning there can be races between the ports on a bad day if a device ...

CVE-2026-64040 cachefiles: Fix error return when vfs_mkdir() fails

In the Linux kernel, the following vulnerability has been resolved: cachefiles: Fix error return when vfsmkdir fails When vfsmkdir fails, the error code is not extracted from the returned error pointer. This causes mkdirerror to be reached with ret=0, which leads to returning ERRPTR0 NULL instead...
