The vulnerability of the sch_reboot() function in the adm.cgi script of the Wavlink AC3000 (WL-WN533A8) router’s microprogramming system allows a hacker to execute arbitrary commands.

The vulnerability of the schreboot function in the adm.cgi script of the Wavlink AC3000 WL-WN533A8 router’s microprogramming system is related to the lack of measures taken to manage data at the control level. Exploiting this vulnerability allows a remote attacker to execute arbitrary commands by...

DEBIAN-CVE-2024-57996

In the Linux kernel, the following vulnerability has been resolved: netsched: schsfq: don't allow 1 packet limit The current implementation does not work correctly with a limit of 1. iproute2 actually checks for this and this patch adds the check in kernel as well. This fixes the following...

In the Linux kernel, the following vulnerability has been resolved: netsched: schsfq: don't allow 1 packet limit The current implementation does not work correctly with a limit of 1. iproute2 actually checks for this and this patch adds the check in kernel as well. This fixes the following...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: sched: schcake: Fixed the logic for accounting bulk flows in order to ensure host fairness. In schcake, we keep track of the number of active bulk flows per host. This is done when running in the dst/src host fairness mode, which...

CVE-2024-53164

In the Linux kernel, the following vulnerability has been resolved: net: sched: fix ordering of qlen adjustment Changes to sch-q.qlen around qdisctreereducebacklog need to happen before a call to said function because otherwise it may fail to notify parent qdiscs when the child is about to become...

The vulnerability of the sch_ets component in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the schets component in the Linux operating system’s kernel is related to a memory corruption in the etsqdiscchange function. Exploiting this vulnerability can allow an attacker to cause a service failure...

The vulnerability of the cakedestroy() function in the sch_cake component of the Linux operating system allows a malicious actor to escalate their privileges or cause service failures.

The vulnerability of the cakedestroy function in the schcake component of the Linux operating system’s kernel is related to the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to increase their privileges or cause service interruptions...

DEBIAN-CVE-2024-46828

In the Linux kernel, the following vulnerability has been resolved: sched: schcake: fix bulk flow accounting logic for host fairness In schcake, we keep track of the count of active bulk flows per host, when running in dst/src host fairness mode, which is used as the round-robin weight when...

CVE-2024-46800

A use-after-free vulnerability was found in the Linux kernel. If netemdequeue enqueues a packet to inner qdisc and that qdisc returns NETXMITSTOLEN, the packet is dropped but qdisctreereducebacklog is not called to update the parent's q.qlen. Mitigation Mitigation for this issue is either not...

CVE-2024-46800 sch/netem: fix use after free in netem_dequeue

In the Linux kernel, the following vulnerability has been resolved: sch/netem: fix use after free in netemdequeue If netemdequeue enqueues packet to inner qdisc and that qdisc returns NETXMITSTOLEN. The packet is dropped but qdisctreereducebacklog is not called to update the parent's q.qlen,...

SUSE CVE-2024-36978

In the Linux kernel, the following vulnerability has been resolved: net: sched: schmultiq: fix possible OOB write in multiqtune q-bands will be assigned to qopt-bands to execute subsequent code logic after kmalloc. So the old q-bands should not be used in kmalloc. Otherwise, an out-of-bounds writ...

UBUNTU-CVE-2021-47598

In the Linux kernel, the following vulnerability has been resolved: schcake: do not call cakedestroy from cakeinit qdiscs are not supposed to call their own destroy method from init, because core stack already does that. syzbot was able to trigger use after free: DEBUGLOCKSWARNONlock-magic != loc...

SUSE CVE-2022-3586

A flaw was found in the Linux kernel's networking code. A use-after-free was found in the way the schsfb enqueue function used the socket buffer SKB cb field after the same SKB had been enqueued and freed into a child qdisc. This flaw allows a local, unprivileged user to crash the system, causing...
