kernel: net/sched: cls_u32 component reference counter leak if tcf_change_indev() fails

A double-free flaw was found in u32setparms in net/sched/clsu32.c in the Network Scheduler component in the Linux kernel. This flaw allows a local attacker to use a failure event to mishandle the reference counter, leading to a local privilege escalation threat...

The vulnerability of the u32_set_parms() function in the net/sched/cls_u32.c module of the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of data.

The vulnerability of the u32setparms function in the net/sched/clsu32.c module of the Linux operating system is related to incorrect handling of usage counters. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of data...
