Title
net: seeq: Fix use after free vulnerability in ether3 Driver Due to Race Condition
Summary
In the Linux kernel, the following vulnerability has been resolved: net: seeq: Fix use after free vulnerability in ether3 Driver Due to Race Condition In the ether3_probe function, a timer is initialized with a callback function ether3_ledoff, bound to &prev(dev)->timer. Once the timer is started, there is a risk of a race condition if the module or device is removed, triggering the ether3_remove function to perform cleanup. The sequence of operations that may lead to a UAF bug is as follows: CPU0 CPU1 | ether3_ledoff ether3_remove | free_netdev(dev); | put_devic | kfree(dev); | | ether3_outw(priv(dev)->regs.config2 |= CFG2_CTRLO, REG_CONFIG2); | // use dev Fix it by ensuring that the timer is canceled before proceeding with the cleanup in ether3_remove.

A remote peer can keep the LED timer armed via received frames, but local access is required to reach the vulnerable free.\nAC:L - The attacker controls both sides of the race \u2014 traffic on the interface arms the 20 ms LED timer, and `ether3_close()` never cancels it, so a pending timer at `free_netdev()` time is essentially deterministic rather than a tight window. Heap grooming to reallocate the freed netdev is likewise under attacker control.\nPR:L - An unprivileged local user can drive the TX/RX paths that arm the timer and can spray the kernel heap to reclaim the freed `alloc_etherdev()` chunk, matching this CNA\u0027s scoring of the identical timer-not-cancelled-in-remove bug class. No capability check gates the attacker-controlled half of the race.\nUI:N - No victim action is needed beyond the driver teardown itself; once the timer is pending, the use-after-free fires automatically from softirq context roughly 20 ms later with no user involvement.\nS:U - The corruption is confined to kernel slab memory and kernel control flow \u2014 the same security authority that contains the flaw. There is no hypervisor, IOMMU, or sandbox boundary crossed.\nC:H - The callback reads `private-\u003edev`, `priv(dev)-\u003eseeq`, and `regs.config2` out of freed memory; once that allocation is reclaimed, the driver operates on attacker- or victim-controlled contents, and the read-modify-write of `config2` plus the pointer-derived MMIO access provide an information-disclosure channel. Kernel use-after-free is scored High.\nI:H - `regs.config2 |= CFG2_CTRLO` writes back into the freed object, and the subsequent `writew()` targets `priv(dev)-\u003eseeq + 0x80` \u2014 an address sourced from freed memory. Reclaiming the allocation turns this into a 16-bit write to an attacker-chosen kernel address from softirq context, a control-flow-hijack-capable primitive.\nA:H - Even without successful reclaim, `ether3_ledoff()` dereferences poisoned/freed pointers and performs an I/O write through a garbage `seeq` pointer, producing an unhandled fault in timer softirq context \u2014 a kernel oops or panic. The freed `timer_list` also leaves the timer subsystem traversing released memory."

Once the timer is\\nstarted, there is a risk of a race condition if the module or device\\nis removed, triggering the ether3_remove function to perform cleanup.\\nThe sequence of operations that may lead to a UAF bug is as follows:\\n\\nCPU0                                    CPU1\\n\\n                      |  ether3_ledoff\\nether3_remove         |\\n  free_netdev(dev);   |\\n  put_devic           |\\n  kfree(dev);         |\\n |  ether3_outw(priv(dev)-\u003eregs.config2 |= CFG2_CTRLO, REG_CONFIG2);\\n                      | // use dev\\n\\nFix it by ensuring that the timer is canceled before proceeding with\\nthe cleanup in ether3_remove.\"}], \"cpeApplicability\": [{\"nodes\": [{\"negate\": false, \"cpeMatch\": [{\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"4.19.323\", \"versionStartIncluding\": \"4.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.4.285\", \"versionStartIncluding\": \"4.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.10.227\", \"versionStartIncluding\": \"4.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"5.15.168\", \"versionStartIncluding\": \"4.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.1.113\", \"versionStartIncluding\": \"4.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.6.54\", \"versionStartIncluding\": \"4.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.10.13\", \"versionStartIncluding\": \"4.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.11.2\", \"versionStartIncluding\": \"4.15\"}, {\"criteria\": \"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*\", \"vulnerable\": true, \"versionEndExcluding\": \"6.12\", \"versionStartIncluding\": \"4.15\"}], \"operator\": \"OR\"}]}], \"providerMetadata\": {\"orgId\": \"416baaa9-dc9f-4396-8d5f-8c081fb06d67\", \"shortName\": \"Linux\", \"dateUpdated\": \"2025-05-04T09:38:59.872Z\"}}}",
