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.

"value": "AV:L - The free side is a local operation (module unload or sysfs driver unbind on the ecard bus); Acorn podules are not runtime hot-pluggable, so there is no physical or remote path that triggers `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."

"value": "In the Linux kernel, the following vulnerability has been resolved:\n\nnet: seeq: Fix use after free vulnerability in ether3 Driver Due to Race Condition\n\nIn the ether3_probe function, a timer is initialized with a callback\nfunction ether3_ledoff, bound to \u0026prev(dev)-\u003etimer. 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."

"value": "AV:L - The free side is a local operation (module unload or sysfs driver unbind on the ecard bus); Acorn podules are not runtime hot-pluggable, so there is no physical or remote path that triggers `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."
