kernel: smc91x: fix broken irq-context in PREEMPT_RT

A locking context bug was found in the Linux kernel's smc91x Ethernet driver on PREEMPTRT kernels. The smcspecialtrylock function disables IRQs but smcspecialunlock does not properly restore IRQs on PREEMPTRT. This mismatch causes RCU read unlock to fail in devqueuexmit, triggering a "workqueue...

The vulnerability of the rcu_scale_writer() function in the kernel/rcu/rcuscale.c module of the synchronization subsystem in Linux multi-threaded kernel systems allows a hacker to cause a service failure.

The vulnerability of the rcuscalewriter function in the kernel/rcu/rcuscale.c module of the synchronization subsystem in Linux multi-threaded kernel systems is related to the absence of initialization of the buffer. Exploiting this vulnerability can allow an attacker to cause a service failure...

kernel: net/sched: act_api: use RCU with deferred freeing for action lifecycle

A flaw was found in the Linux kernel's networking scheduler. A race condition, which is a problem that occurs when multiple operations try to access the same resource at the same time, exists when network filter operations are run concurrently. This can lead to a Use-After-Free UAF vulnerability,...
