CVE-2026-98369

The Linux kernel is affected by a vulnerability in the xfrm subsystem where xfrm_trans_reinject was converted from a tasklet to a workqueue. Because workqueue workers run in process context, they fail to enter an RCU read-side critical section, causing RCU lockdep warnings when invoking finish ca...

CVE-2026-98342

The Linux kernel dmaengine component contains a vulnerability where dma_device_release() unlinks a device using list_del_RCU() and subsequently frees it without ensuring a grace period. This allows concurrent RCU readers in dma_issue_pending_all() to access the device after it has been freed, pot...

CVE-2026-98320

The Linux kernel is affected by a vulnerability in the netfilter flowtable component. The root cause is that nf_ct_put() releases the ct->ext area immediately, which allows the datapath to potentially refer to the incorrect conntrack due to rcu typesafe semantics. To resolve this, the kernel m...

CVE-2026-98243

A vulnerability exists in the Linux kernel 's dma-buf/dma-fence component. A previous patch intended to prevent a NULL pointer dereference by testing the ops pointer instead of the signaled bit inadvertently removed RCU protection for many dma_fence implementations. This loss of protection can le...
