CVE-2026-89941: Undefined Security Weakness
In the Linux kernel, the following vulnerability has been resolved: iio: buffer: Make IIO DMA fence release RCU-safe The dmafence documentation states that if a custom release implementation is provided, the dmafence object must be freed in an RCU-safe way. The current iiodmafence implementation...
CVE-2026-89545
CVE-2026-89545 is a use-after-free in the Linux kernel's sunrpc subsystem. The function svc_rqst_free() frees rqstp->rq_argp and rqstp->rq_resp synchronously via kfree(), while the parent rqstp struct is deferred via kfree_rcu(). After svc_exit_thread() removes the thread from the RCU list,...
