CVSS: 6.4EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39503 – netfilter: ipset: Fix race between namespace cleanup and gc in the list:set type
https://notcve.org/view.php?id=CVE-2024-39503
In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: Fix race between namespace cleanup and gc in the list:set type Lion Ackermann reported that there is a race condition between namespace cleanup in ipset and the garbage collection of the list:set type. The namespace cleanup can destroy the list:set type of sets while the gc of the set type is waiting to run in rcu cleanup. The latter uses data from the destroyed set which thus leads use after free. The patch contains the following parts: - When destroying all sets, first remove the garbage collectors, then wait if needed and then destroy the sets. - Fix the badly ordered "wait then remove gc" for the destroy a single set case. - Fix the missing rcu locking in the list:set type in the userspace test case. - Use proper RCU list handlings in the list:set type. The patch depends on c1193d9bbbd3 (netfilter: ipset: Add list flush to cancel_gc). • https://git.kernel.org/stable/c/c7f2733e5011bfd136f1ca93497394d43aa76225 https://git.kernel.org/stable/c/a24d5f2ac8ef702a58e55ec276aad29b4bd97e05 https://git.kernel.org/stable/c/c2dc077d8f722a1c73a24e674f925602ee5ece49 https://git.kernel.org/stable/c/653bc5e6d9995d7d5f497c665b321875a626161c https://git.kernel.org/stable/c/b93a6756a01f4fd2f329a39216f9824c56a66397 https://git.kernel.org/stable/c/97f7cf1cd80eeed3b7c808b7c12463295c751001 https://git.kernel.org/stable/c/970709a67696b100a57b33af1a3d75fc34b747eb https://git.kernel.org/stable/c/c0761d1f1ce1d5b85b5e82bbb714df12d • CWE-416: Use After Free •
CVSS: 6.7EPSS: 0%CPEs: 7EXPL: 0CVE-2024-39502 – ionic: fix use after netif_napi_del()
https://notcve.org/view.php?id=CVE-2024-39502
In the Linux kernel, the following vulnerability has been resolved: ionic: fix use after netif_napi_del() When queues are started, netif_napi_add() and napi_enable() are called. If there are 4 queues and only 3 queues are used for the current configuration, only 3 queues' napi should be registered and enabled. The ionic_qcq_enable() checks whether the .poll pointer is not NULL for enabling only the using queue' napi. Unused queues' napi will not be registered by netif_napi_add(), so the .poll pointer indicates NULL. But it couldn't distinguish whether the napi was unregistered or not because netif_napi_del() doesn't reset the .poll pointer to NULL. So, ionic_qcq_enable() calls napi_enable() for the queue, which was unregistered by netif_napi_del().

CVSS: 4.7EPSS: 0%CPEs: 8EXPL: 0CVE-2024-39501 – drivers: core: synchronize really_probe() and dev_uevent()
https://notcve.org/view.php?id=CVE-2024-39501
In the Linux kernel, the following vulnerability has been resolved: drivers: core: synchronize really_probe() and dev_uevent() Synchronize the dev->driver usage in really_probe() and dev_uevent(). These can run in different threads, what can result in the following race condition for dev->driver uninitialization: Thread #1: ========== really_probe() { ... probe_failed: ... device_unbind_cleanup(dev) { ... dev->driver = NULL; // <= Failed probe sets dev->driver to NULL ... } ... } Thread #2: ========== dev_uevent() { ... if (dev->driver) // If dev->driver is NULLed from really_probe() from here on, // after above check, the system crashes add_uevent_var(env, "DRIVER=%s", dev->driver->name); ... } really_probe() holds the lock, already. So nothing needs to be done there. dev_uevent() is called with lock held, often, too. But not always. What implies that we can't add any locking in dev_uevent() itself. So fix this race by adding the lock to the non-protected path. • https://git.kernel.org/stable/c/239378f16aa1ab5c502e42a06359d2de4f88ebb4 https://git.kernel.org/stable/c/bb3641a5831789d83a58a39ed4a928bcbece7080 https://git.kernel.org/stable/c/13d25e82b6d00d743c7961dcb260329f86bedf7c https://git.kernel.org/stable/c/760603e30bf19d7b4c28e9d81f18b54fa3b745ad https://git.kernel.org/stable/c/ec772ed7cb21b46fb132f89241682553efd0b721 https://git.kernel.org/stable/c/08891eeaa97c079b7f95d60b62dcf0e3ce034b69 https://git.kernel.org/stable/c/a42b0060d6ff2f7e59290a26d5f162a3c6329b90 https://git.kernel.org/stable/c/95d03d369ea647b89e950667f1c3363ea • CWE-362: Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition') •
