Doc Type: If docs needed, set a value
Doc Text:
A double-free flaw was found in u32_set_parms in net/sched/cls_u32.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.

Description Alex 2023-07-24 14:28:28 UTC 
A flaw in the Linux Kernel found. A use-after-free vulnerability in the Linux kernel's net/sched: cls_u32 component can be exploited to achieve local privilege escalation. If tcf_change_indev() fails, u32_set_parms() will immediately return an error after incrementing or decrementing the reference counter in tcf_bind_filter(). If an attacker can control the reference counter and set it to zero, they can cause the reference to be freed, leading to a use-after-free vulnerability.
