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...

kernel: net/sched: act_ct: Only release RCU read lock after ct_ft

A flaw was found in the Linux kernel. A race condition in the actct module, specifically during the flow table lookup, can lead to a Use-After-Free UAF vulnerability. This occurs because a critical lock is released prematurely, allowing a memory object to be freed while still in use. An attacker...

kernel: net/sched: cls_route: fix fastmap use-after-free on filter

A flaw was found in the Linux kernel's net/sched: clsroute component. A race condition exists in the route4 classifier's fastmap cache, where a reader can re-cache a pointer to a filter that has already been freed by a writer. This can lead to a use-after-free condition, allowing subsequent packe...

CVE-2026-90248

A flaw was found in the Linux kernel's network scheduler component net/sched: clsapi. A race condition exists in the tcnewtfilter function during the insertion of a new protocol. If a process loses a race to insert a protocol, its error handling path may incorrectly remove an active network...

CVE-2026-90058

A flaw was found in the Linux kernel's networking scheduler net/sched. A local unprivileged user with CAPNETADMIN capabilities within a user namespace could provide a crafted size table to a deficit scheduler, such as DRR or ETS, with a small quantum. This manipulation can cause the scheduler to...
