QEMU: virtio-net: heap use-after-free in virtio_net_receive_rcu

A use-after-free vulnerability was found in the virtio-net device of QEMU. It could occur when the descriptor's address belongs to the non direct access region, due to numbuffers being set after the virtqueue elem has been unmapped. A malicious guest could use this flaw to crash QEMU, resulting i...

Integer overflow

In Weidmueller Industrial WLAN devices in multiple versions an exploitable denial-of-service vulnerability exists in ServiceAgent functionality. A specially crafted packet can cause an integer underflow, triggering a large memcpy that will access unmapped or out-of-bounds memory. An attacker can...

PT-2021-8275 · Linux +2 · Linux Kernel +2

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to the GTDT driver in the Linux kernel. When the driver probe fails due to invalid firmware properties, it unmaps the interrupt that it mapped earlier. However, it...

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to the mt76 driver, specifically the mt7615 component, where the first pointer in the txp needs to be unmapped to prevent DMA mapping entries from leaking...

An issue was discovered in the Linux kernel 3.11 through 5.10.16 as used by Xen. To service requests to the PV backend the driver maps grant references provided by the frontend. In this process errors may be encountered. In one case an error encountered earlier might be discarded by later processing resulting in the caller assuming successful mapping and hence subsequent operations trying to access space that wasn't mapped. In another case internal state would be insufficiently updated preventing safe recovery from the error. This affects drivers/block/xen-blkback/blkback.c.
