CVE-2023-54326

CVE-2023-54326 — Linux kernel (misc: pci_endpoint_test) — A race exists where freeing IRQs after the test device is removed can allow IRQs to arrive while memory already freed, leading to an oops in the IRQ handler. The advisory states the issue is solved by freeing the device IRQs before removin...

CVE-2023-54322

CVE-2023-54322 (Linux kernel, arm64) : The vulnerability arises in stack trace filtering where filter_irq_stacks() is supposed to drop irq-entry related frames, but on arm64 the irq entry point (gic_handle_irq) is not present when CONFIG_FUNCTION_GRAPH_TRACER is not enabled. This can cause uninte...

CVE-2023-54288 wifi: mac80211: fortify the spinlock against deadlock by interrupt

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: fortify the spinlock against deadlock by interrupt In the function ieee80211txdequeue there is a particular locking sequence: begin: spinlock&local-queuestopreasonlock; qstopped = local-queuestopreasonsq;...

CVE-2023-54288

The CVE-2023-54288 entry pertains to the Linux kernel’s wifi mac80211 stack. A deadlock risk arises in ieee80211_tx_dequeue() due to a race between spin_lock and spin_unlock around queue_stop_reason_lock when an asynchronous interrupt occurs, potentially re-locking the same spinlock. This can lea...
