The vulnerability of the recv_work() function in the drivers/block/nbd.c module of the Linux kernel’s block devices driver allows a hacker to cause a service failure.
The vulnerability of the recvwork function in the drivers/block/nbd.c module of the Linux block devices driver leads to mutual locking. Exploiting this vulnerability can allow an attacker to cause a service failure...
CVE-2026-24054
Kata Containers Runtime (kata-containers) versions prior to 3.26.0 are affected. When a container image is malformed or has no layers, containerd bind-mounts an empty snapshotter directory for the container rootfs; the Kata runtime then mounts rootfs and may detect it as a block device, causing t...
