CVE-2026-43469

Summary: CVE-2026-43469 affects the Linux kernel xprtrdma component. The root cause is that rpcrdma_post_recvs() may exit early or fail to create a work request without decrementing ep->re_receiving. This miscount can cause rpcrdma_xprt_drain() to hang, leaving the completion blocked and poten...

CVE-2026-43402

Summary: CVE-2026-43402 affects the Linux kernel where kthread exit paths were consolidated to prevent a use-after-free in the kthread/pid data cleanup, after crashes traced to corrupted RCU function pointers during KUnit tests. The root cause involves a pid hashtable conversion changing structur...

CVE-2026-43358

CVE-2026-43358 affects the Linux kernel's btrfs filesystem. The vulnerability is a missing RCU unlock in the error path of try_release_subpage_extent_buffer(), where rcu_read_lock() should be held before exiting the loop because an rcu_read_unlock() occurs past the loop. The issue was identified ...
