Vulnerability from cvelistv5
Published

Severity ?
7.8 (High) - CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: forcedeth: fix UAF of txrx_stats in nv_remove nv_remove() frees the per-CPU txrx_stats before unregister_netdev(). Until unregister completes, ndo_get_stats64, the NAPI/xmit data path, and nv_close()/drain may still access txrx_stats, leading to a use-after-free. Free the stats only after unregister_netdev().

\"scenarios\": [{\"lang\": \"en\", \"value\": \"AV:L - The UAF is opened in nv_remove() during local PCI/driver teardown (sysfs unbind, module unload, or hot-unplug); although NAPI/xmit and stats readers can run concurrently on still-registered netdev traffic, there is no standalone remote path into nv_remove itself.\\nAC:L - Once teardown starts, unregister_netdev() deterministically calls nv_close()\\u2192nv_drain_tx(), which increments freed txrx_stats when TX skbs remain, and an attacker can also drive the race by timing unbind against stats polling or packet I/O they control.\\nPR:L - Privileged teardown opens the window, but unprivileged peers can supply the concurrent netdev access (rtnetlink/sysfs stats via nv_get_stats64, and RX/TX on the still-up interface) that performs the UAF; per CNA driver-removal UAF precedent and the higher-severity tiebreak, PR:L.\\nUI:N - No separate victim action is required beyond routine driver removal or module unload on a live interface; monitoring daemons and network traffic can hit the freed stats automatically during the unregister window without user cooperation.\\nS:U - Impact is kernel heap corruption and crash/privilege escalation within the host kernel security authority; it does not cross VM, hypervisor, IOMMU, or container sandbox boundaries.\\nC:H - The bug is a kmalloc-backed per-CPU UAF: nv_get_stats64 reads freed nv_txrx_stats counters via per_cpu_ptr(), and once the slab is reallocated an attacker can obtain arbitrary kernel memory disclosure.\\nI:H - Freed txrx_stats are updated from NAPI/xmit and nv_drain_tx() via __this_cpu_inc/add on attacker-influenced traffic, enabling heap grooming and controlled writes through the dangling per-CPU pointer for code execution.\\nA:H - Use-after-free dereferences of txrx_stats during netdev teardown reliably cause kernel oops/panic (as in the fix description), and even unsuccessful exploitation still crashes the system when concurrent RX/TX or drain paths touch freed memory.\"}]}], \"affected\": [{\"repo\": \"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git\", \"vendor\": \"Linux\", \"product\": \"Linux\", \"versions\":
