SUSE CVE-2024-45818

The hypervisor contains code to accelerate VGA memory accesses for HVM guests, when the virtual VGA is in "standard" mode. Locking involved there has an unusual discipline, leaving a lock acquired past the return from the function that acquired it. This behavior results in a problem when emulatin...

In the Linux kernel, the following vulnerability has been resolved: smb: client: fix potential deadlock when releasing mids All releasemid callers seem to hold a reference of @mid so there is no need to call krefput&mid-refcount, releasemid under @server-midlock spinlock. If they don't, then an...

kernel: wifi: rt2x00: restart beacon queue when hardware reset

A flaw was found in the Linux kernel. When a hardware reset is triggered, all registers are reset, so all queues are forced to stop in the hardware interface. However, mac80211 will not automatically stop the queue. If the beacon queue is not manually stopped, it will be deadlocked and unable to...
