7.8 HIGH — CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H

Description

In the Linux kernel, the following vulnerability has been resolved: net/sched: act_gate: snapshot parameters with RCU on replace The gate action can be replaced while the hrtimer callback or dump path is walking the schedule list. Convert the parameters to an RCU-protected snapshot and swap updates under tcf_lock, freeing the previous snapshot via call_rcu(). When REPLACE omits the entry list, preserve the existing schedule so the effective state is unchanged.

Affected configurations

• linux linux kernel (>= 5.8.1 < 5.10.253) • linux linux kernel (>= 5.11 < 6.1.167) • linux linux kernel (>= 6.2 < 6.6.130) • linux linux kernel (>= 6.7 < 6.12.78) • linux linux kernel (>= 6.13 < 6.18.18) • linux linux kernel (>= 6.19 < 6.19.8) • linux linux kernel 5.8 • linux linux kernel 7.0
