In the Linux kernel, the following vulnerability has been resolved: sched/fair: Clear reldeadline when initializing forked entities A yield-triggered crash can happen when a newly forked schedentity enters the fair class with se-reldeadline unexpectedly set. The failing sequence is: 1. A task is...

kernel: net/sched: Always pass notifications when child class becomes empty

A use-after-free UAF vulnerability was found in the Linux kernel's net/sched subsystem, specifically in the Credit-Based Shaper CBS qdisc implementation schcbs. The vulnerability occurs because the CBS qdisc's reset function qdiscresetqueue only resets its internal queue but fails to reset its...

DEBIAN-CVE-2025-21919

In the Linux kernel, the following vulnerability has been resolved: sched/fair: Fix potential memory corruption in childcfsrqonlist childcfsrqonlist attempts to convert a 'prev' pointer to a cfsrq. This 'prev' pointer can originate from struct rq's leafcfsrqlist, making the conversion invalid and...

CVE-2021-47209

The CVE-2021-47209 issue affects the Linux kernel’s scheduler, specifically sched/fair with the cfs_rq handling. A use-after-free of a cfs_rq occurs when a dying task group is unlinked or partially unlinked while a concurrent timer/race (tg_unthrottle_up via sched_cfs_period_timer) can re-add cfs...

Security Advisory Description An issue was discovered in the Linux kernel before 5.2.6. On NUMA systems, the Linux fair scheduler has a use-after-free in shownumastats because NUMA fault statistics are inappropriately freed, aka CID-16d51a590a8c. CVE-2019-20934 Impact There is no impact; F5...

SUSE CVE-2018-20784

In the Linux kernel before 4.20.2, kernel/sched/fair.c mishandles leaf cfsrq's, which allows attackers to cause a denial of service infinite loop in updateblockedaverages or possibly have unspecified other impact by inducing a high load...

Denial Of Service

Linux kernel is vulnerable to denial of service. Linux fair scheduler has a use-after-free in shownumastats because NUMA fault statistics are inappropriately freed. A flaw was found in the Linux kernels implementation of displaying NUMA statistics, where displaying the scheduler statistics could...
