An issue arises because it calls\nqdisc_tree_reduce_backlog before it reincrements the qlen. If qlen drops\nto zero, but peek returns an skb, the parent's qlen_notify callback will\nbe executed even though codel still has 1 packet on the queue and, thus,\nwill mistakenly deactivate the parent's class causing issues like a wild\nmemory access when qfq has codel as a child:\n\n[ 36.339843][ T370] Oops: general protection fault, probably for non-canonical address 0xfbd59c0000000024:

The flaw corrupts in-kernel QFQ/CoDel scheduler structures and memory within the same kernel security domain; it does not cross VM, container, or IOMMU authority boundaries.\nC:H - False qlen_notify prematurely deactivates QFQ aggregates while packets remain; the fix commit shows KASAN wild-memory-access on poisoned aggregate list nodes in qfq_deactivate_agg(), giving attacker-influenced reads from freed/corrupted scheduler memory.\nI:H - Corrupted aggregate/class linkage leads to invalid hlist operations and inconsistent scheduler state that can be steered with heap layout control, yielding memory corruption primitives usable for arbitrary kernel writes or control-flow hijack.\nA:H - The published oops is a general protection fault from corrupted QFQ state during qdisc teardown, and the same corruption during live packet scheduling can reliably kernel-panic or hang affected hosts."}]}], "affected": [{"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "cc71a757da78dd4aa1b4a9b19cb011833730ccf2", "lessThan": "bb9cfd874ee884117b33e92a002b9a45b48202f4", "versionType": "git"}, {"status": "affected", "version": "eda741fe155ddf5ecd2dd3bfbd4fc3c0c7dbb450", "lessThan": "7a05af7f58566682b73578b72ca8e53a268c43bd", "versionType": "git"}, {"status": "affected", "version": "829c49b6b2ff45b043739168fd1245e4e1a91a30", "lessThan": "eba49fd85995a3851c597fa2d214f8d21736e1d8", "versionType": "git"}, {"status": "affected", "version": "2f9761a94bae33d26e6a81b31b36e7d776d93dc1", "lessThan": "e8c6dbadf139cb14ea6ed14add6ed6e88504dedd", "versionType": "git"}, {"status": "affected", "version": "4d55144b12e742404bb3f8fee6038bafbf45619d", "lessThan": "e4615aa6bb7802944ae790cb4b3ef8c1b7491af3", "versionType": "git"}, {"status": "affected", "version": "342debc12183b51773b3345ba267e9263bdfaaef", "lessThan": "755108bb7a5083e911294c416cfea605dc75632f", "versionType": "git"}, {"status": "affected", "version": "342debc12183b51773b3345ba267e9263bdfaaef", "lessThan": "91e0a793a72374c20ab31a40ccec21373e82e973", "versionType": "git"}, {"status": "affected", "version": "342debc12183b51773b3345ba267e9263bdfaaef", "lessThan": "52f1da34c9f4d5bdc1e8b44242da5c7ba8db85f3", "versionType": "git"}, {"status": "affected", "version": "7a742a9506849d1c1aa71e36c89855ceddc7d58e", "versionType": "git"}, {"status": "affected", "version": "e73c838c80dccb9e4f19becc11d9f3cb4a27d483", "versionType": "git"}, {"status": "affected", "version": "a57fe60ef4cf96bfbb6b58397ec28bdb5a5c6b31", "versionType": "git"}, {"status": "affected", "version": "5.10.241", "lessThan": "5.10.261", "versionType": "semver"}, {"status": "affected", "version": "5.15.190", "lessThan": "5.15.212", "versionType": "semver"}, {"status": "affected", "version": "6.1.135", "lessThan": "6.1.178", "versionType": "semver"}, {"status": "affected", "version": "6.6.88", "lessThan": "6.6.145", "versionType": "semver"}, {"status": "affected", "version": "6.12.24", "lessThan": "6.12.97", "versionType": "semver"}, {"status": "affected", "version": "5.4.297", "lessThan": "5.5", "versionType": "semver"}, {"status": "affected", "version": "6.13.12", "lessThan": "6.14", "versionType": "semver"}, {"status": "affected", "version": "6.14.3", "lessThan": "6.15", "versionType": "semver"}], "programFiles": ["net/sched/sch_codel.c"], "defaultStatus": "unaffected"}, {"repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "vendor": "Linux", "product": "Linux", "versions": [{"status": "affected", "version": "6.15"}, {"status": "unaffected", "version": "0", "lessThan": "6.15", "versionType": "semver"}, {"status": "unaffected", "version": "5.10.261", "versionType": "semver", "lessThanOrEqual": "5.10.*"}, {"status": "unaffected", "version": "5.15.212", "versionType": "semver", "lessThanOrEqual": "5.15.*"}, {"status": "unaffected", "version": "6.1.178", "versionType": "semver", "lessThanOrEqual": "6.1.*"}, {"status": "unaffected", "version": "6.6.145", "versionType": "semver", "lessThanOrEqual": "6.6.*"}, {"status": "unaffected", "version": "6.12.97", "versionType": "semver", "lessThanOrEqual": "6.12.*"}, {"status": "unaffected", "version": "6.18.40", "versionType": "semver", "lessThanOrEqual": "6.18.*"}, {"status": "unaffected", "version": "7.1.5", "versionType": "semver", "lessThanOrEqual": "7.1.*"}, {"status": "unaffected", "version": "7.2", "versionType": "original_commit_for_fix", "lessThanOrEqual": "*"}], "programFiles": ["net/sched/sch_codel.c"], "defaultStatus": "affected"}], "references": [{"url": "https://git.kernel.org/stable/c/bb9cfd874ee884117b33e92a002b9a45b48202f4"}, {"url": "https://git.kernel.org/stable/c/7a05af7f58566682b73578b72ca8e53a268c43bd"}, {"url": "https://git.kernel.org/stable/c/eba49fd85995a3851c597fa2d214f8d21736e1d8"}, {"url": "https://git.kernel.org/stable/c/e8c6dbadf139cb14ea6ed14add6ed6e88504dedd"}, {"url": "https://git.kernel.org/stable/c/e4615aa6bb7802944ae790cb4b3ef8c1b7491af3"}, {"url": "https://git.kernel.org/stable/c/755108bb7a5083e911294c416cfea605dc75632f"}, {"url": "https://git.kernel.org/stable/c/91e0a793a72374c20ab31a40ccec21373e82e973"}, {"url": "https://git.kernel.org/stable/c/52f1da34c9f4d5bdc1e8b44242da5c7ba8db85f3"}], "x_generator": {"engine": "bippy-1.2.0"}, "descriptions": [{"lang": "en", "value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet/sched: sch_codel: Do not call qdisc_tree_reduce_backlog during peek before restoring qlen\n\nWhenever codel drops packets during peek, it calls\nqdisc_tree_reduce_backlog.
