CVE-2022-47929

CVE-2022-47929 is a Linux kernel vulnerability: a NULL pointer dereference in the traffic control subsystem (affecting qdisc_graft in net/sched/sch_api.c) that allows an unprivileged user to trigger a denial of service (system crash) via crafted tc qdisc/class configurations. Exploitation is loca...

Linux kernel code vulnerabilities

Linux kernel, the kernel used by the Linux Foundation's open source operating system Linux, is vulnerable to a denial-of-service attack in versions of Linux kernel prior to 6.1.6. In affected versions of the Linux kernel, a NULL pointer dereference error in the flow control subsystem allows an...

CVE-2022-47929

In the Linux kernel before 6.1.6, a NULL pointer dereference bug in the traffic control subsystem allows an unprivileged user to trigger a denial of service system crash via a crafted traffic control configuration that is set up with "tc qdisc" and "tc class" commands.
