https://notcve.org/view.php?id=CVE-2025-38351
19 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: KVM: x86/hyper-v: Skip non-canonical addresses during PV TLB flush In KVM guests with Hyper-V hypercalls enabled, the hypercalls HVCALL_FLUSH_VIRTUAL_ADDRESS_LIST and HVCALL_FLUSH_VIRTUAL_ADDRESS_LIST_EX allow a guest to request invalidation of portions of a virtual TLB. For this, the hypercall parameter includes a list of GVAs that are supposed to be invalidated. However, when non-canonical GVAs are passed, there is currently no filtering ... • https://git.kernel.org/stable/c/260970862c88b4130e9e12be023c7e2c2d37a966 •

CVE-2025-38350 – net/sched: Always pass notifications when child class becomes empty
https://notcve.org/view.php?id=CVE-2025-38350
19 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: net/sched: Always pass notifications when child class becomes empty Certain classful qdiscs may invoke their classes' dequeue handler on an enqueue operation. This may unexpectedly empty the child qdisc and thus make an in-flight class passive via qlen_notify(). Most qdiscs do not expect such behaviour at this point in time and may re-activate the class eventually anyways which will lead to a use-after-free. The referenced fix commit attemp... • https://git.kernel.org/stable/c/1034e3310752e8675e313f7271b348914008719a •

CVE-2025-38349 – eventpoll: don't decrement ep refcount while still holding the ep mutex
https://notcve.org/view.php?id=CVE-2025-38349
18 Jul 2025 — In the Linux kernel, the following vulnerability has been resolved: eventpoll: don't decrement ep refcount while still holding the ep mutex Jann Horn points out that epoll is decrementing the ep refcount and then doing a mutex_unlock(&ep->mtx); afterwards. That's very wrong, because it can lead to a use-after-free. That pattern is actually fine for the very last reference, because the code in question will delay the actual call to "ep_free(ep)" until after it has unlocked the mutex. But it's wrong for the m... • https://git.kernel.org/stable/c/58c9b016e12855286370dfb704c08498edbc857a •
