kernel: net/sched: taprio: fix use-after-free in advance_sched() on schedule switch

A flaw was found in the Linux kernel's networking scheduler, specifically within the taprio module. When the system attempts to switch schedules, a use-after-free vulnerability occurs in the advancesched function. This happens because a pointer to an old schedule entry is still used after the...

ROS-20260923-73-0004

The vulnerability of the advancesched function in the net/sched/schtaprio.c module of the Linux operating system’s traffic management subsystem is related to the dereferencing of a pointer with an expired validity period. Exploiting this vulnerability could allow an attacker to compromise the...

The vulnerability of the advance_sched() function in the net/sched/sch_taprio.c module of the network scheduling subsystem in the Linux operating system allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

CVE-2026-53011: Use After Free

In the Linux kernel, the following vulnerability has been resolved: net/sched: taprio: fix use-after-free in advancesched on schedule switch In advancesched, when shouldchangeschedules returns true, switchschedules is called to promote the admin schedule to oper. switchschedules queues the old op...

CVE-2025-38087: Use After Free

In the Linux kernel, the following vulnerability has been resolved: net/sched: fix use-after-free in tapriodevnotifier Since taprio’s tapriodevnotifier isn’t protected by an RCU read-side critical section, a race with advancesched can lead to a use-after-free. Adding rcureadlock inside...
