kernel: net/sched: cls_fw component can be exploited as result of failure in tcf_change_indev function

A use-after-free vulnerability was found in fwsetparms in net/sched/clsfw.c in network scheduler sub-component in the Linux Kernel. This issue occurs due to a missing sanity check during cleanup at the time of failure, leading to a misleading reference. This may allow a local attacker to gain loc...

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...
