Kernel: denial of service in atm_tc_enqueue in net/sched/sch_atm.c due to type confusion

A denial of service flaw was found in atmtcenqueue in net/sched/schatm.c in the Linux kernel. This issue may allow a local attacker to cause a denial of service due to type confusion. Non-negative numbers could indicate a TCACTSHOT condition rather than valid classification results...

The vulnerability of the `cbs_init()` function in the `net/sched/sch_cbs.c` module of the Linux operating system allows a hacker to cause a service failure.

The vulnerability of the cbsinit function in the net/sched/schcbs.c module of the Linux operating system is related to the assignment of a null pointer. Exploiting this vulnerability could allow an attacker to cause a service failure...

CVE-2021-33630

A NULL pointer dereference flaw was found in the Linux kernel's network scheduler. This issue occurs when offloading is enabled, the cbs instance is not added to the list. The code also incorrectly handles the case when offload is disabled without removing the qdisc. This could allow a local user...
