| CVE-2022-50490(opens NVD record) | High | 7.1 | In the Linux kernel, the following vulnerability has been resolved: bpf: Propagate error from htab_lock_bucket() to userspace In __htab_map_lookup_and_delete_batch() if htab_lock_bucket() returns -EBUSY, it will go to next bucket. Going to next bucket may not only skip the elements in current bucket silently, but also incur out-of-bound memory access or expose kernel memory to userspace if current bucket_cnt is greater than bucket_size or zero. Fixing it by stopping batch operation and returning -EBUSY when htab_lock_bucket() fails, and the application can retry or skip the busy batch as needed. | Oct 4, 2025 |

| CVE-2022-50483(opens NVD record) | High | 7.5 | In the Linux kernel, the following vulnerability has been resolved: net: enetc: avoid buffer leaks on xdp_do_redirect() failure Before enetc_clean_rx_ring_xdp() calls xdp_do_redirect(), each software BD in the RX ring between index orig_i and i can have one of 2 refcount values on its page. We are the owner of the current buffer that is being processed, so the refcount will be at least 1. If the current owner of the buffer at the diametrically opposed index in the RX ring (i.o.w, the other half of this page) has not yet called kfree(), this page's refcount could even be 2. enetc_page_reusable() in enetc_flip_rx_buff() tests for the page refcount against 1, and [ if it's 2 ] does not attempt to reuse it. But if enetc_flip_rx_buff() is put after the xdp_do_redirect() call, the page refcount can have one of 3 values. It can also be 0, if there is no owner of the other page half, and xdp_do_redirect() for this buffer ran so far that it triggered a flush of the devmap/cpumap bulk queue, and the consumers of those bulk queues also freed the buffer, all by the time xdp_do_redirect() returns the execution back to enetc. This is the reason why enetc_flip_rx_buff() is called before xdp_do_redirect(), but there is a big flaw with that reasoning: enetc_flip_rx_buff() will set rx_swbd->page = NULL on both sides of the enetc_page_reusable() branch, and if xdp_do_redirect() returns an error, we call enetc_xdp_free(), which does not deal gracefully with that. In fact, what happens is quite special. The page refcounts start as 1. enetc_flip_rx_buff() figures they're reusable, transfers these rx_swbd->page pointers to a different rx_swbd in enetc_reuse_page(), and bumps the refcount to 2. When xdp_do_redirect() later returns an error, we call the no-op enetc_xdp_free(), but we still haven't lost the reference to that page. A copy of it is still at rx_ring->next_to_alloc, but that has refcount 2 (and there are no concurrent owners of it in flight, to drop the refcount). What really kills the system is when we'll flip the rx_swbd->page the second time around. With an updated refcount of 2, the page will not be reusable and we'll really leak it. Then enetc_new_page() will have to allocate more pages, which will then eventually leak again on further errors from xdp_do_redirect(). The problem, summarized, is that we zeroize rx_swbd->page before we're completely done with it, and this makes it impossible for the error path to do something with it. Since the packet is potentially multi-buffer and therefore the rx_swbd->page is potentially an array, manual passing of the old pointers between enetc_flip_rx_buff() and enetc_xdp_free() is a bit difficult. For the sake of going with a simple solution, we accept the possibility of racing with xdp_do_redirect(), and we move the flip procedure to execute only on the redirect success path. By racing, I mean that the page may be deemed as not reusable by enetc (having a refcount of 0), but there will be no leak in that case, either. Once we accept that, we have something better to do with buffers on XDP_REDIRECT failure. Since we haven't performed half-page flipping yet, we won't, either (and this way, we can avoid enetc_xdp_free() completely, which gives the entire page to the slab allocator). Instead, we'll call enetc_xdp_drop(), which will recycle this half of the buffer back to the RX ring. | Oct 4, 2025 |

| CVE-2025-39948(opens NVD record) | Critical | 9.8 | In the Linux kernel, the following vulnerability has been resolved: ice: fix Rx page leak on multi-buffer frames The ice_put_rx_mbuf() function handles calling ice_put_rx_buf() for each buffer in the current frame. This function was introduced as part of handling multi-buffer XDP support in the ice driver. It works by iterating over the buffers from first_desc up to 1 plus the total number of fragments in the frame, cached from before the XDP program was executed. If the hardware posts a descriptor with a size of 0, the logic used in ice_put_rx_mbuf() breaks. Such descriptors get skipped and don't get added as fragments in ice_add_xdp_frag. Since the buffer isn't counted as a fragment, we do not iterate over it in ice_put_rx_mbuf(), and thus we don't call ice_put_rx_buf(). Because we don't call ice_put_rx_buf(), we don't attempt to re-use the page or free it. This leaves a stale page in the ring, as we don't increment next_to_alloc. The ice_reuse_rx_page() assumes that the next_to_alloc has been incremented properly, and that it always points to a buffer with a NULL page. Since this function doesn't check, it will happily recycle a page over the top of the next_to_alloc buffer, losing track of the old page. Note that this leak only occurs for multi-buffer frames. The ice_put_rx_mbuf() function always handles at least one buffer, so a single-buffer frame will always get handled correctly. It is not clear precisely why the hardware hands us descriptors with a size of 0 sometimes, but it happens somewhat regularly with "jumbo frames" used by 9K MTU. To fix ice_put_rx_mbuf(), we need to make sure to call ice_put_rx_buf() on all buffers between first_desc and next_to_clean. Borrow the logic of a similar function in i40e used for this same purpose. Use the same logic also in ice_get_pgcnts(). Instead of iterating over just the number of fragments, use a loop which iterates until the current index reaches to the next_to_clean element just past the current frame. Unlike i40e, the ice_put_rx_mbuf() function does call ice_put_rx_buf() on the last buffer of the frame indicating the end of packet. For non-linear (multi-buffer) frames, we need to take care when adjusting the pagecnt_bias. An XDP program might release fragments from the tail of the frame, in which case that fragment page is already released. Only update the pagecnt_bias for the first descriptor and fragments still remaining post-XDP program. Take care to only access the shared info for fragmented buffers, as this avoids a significant cache miss. The xdp_xmit value only needs to be updated if an XDP program is run, and only once per packet. Drop the xdp_xmit pointer argument from ice_put_rx_mbuf(). Instead, set xdp_xmit in the ice_clean_rx_irq() function directly. This avoids needing to pass the argument and avoids an extra bit-wise OR for each buffer in the frame. Move the increment of the ntc local variable to ensure its updated *before* all calls to ice_get_pgcnts() or ice_put_rx_mbuf(), as the loop logic requires the index of the element just after the current frame. Now that we use an index pointer in the ring to identify the packet, we no longer need to track or cache the number of fragments in the rx_ring. | Oct 4, 2025 |
| CVE-2025-39945(opens NVD record) | High | 7.8 | In the Linux kernel, the following vulnerability has been resolved: cnic: Fix use-after-free bugs in cnic_delete_task The original code uses cancel_delayed_work() in cnic_cm_stop_bnx2x_hw(), which does not guarantee that the delayed work item 'delete_task' has fully completed if it was already running. Additionally, the delayed work item is cyclic, the flush_workqueue() in cnic_cm_stop_bnx2x_hw() only blocks and waits for work items that were already queued to the workqueue prior to its invocation. Any work items submitted after flush_workqueue() is called are not included in the set of tasks that the flush operation awaits. This means that after the cyclic work items have finished executing, a delayed work item may still exist in the workqueue. This leads to use-after-free scenarios where the cnic_dev is deallocated by cnic_free_dev(), while delete_task remains active and attempt to dereference cnic_dev in cnic_delete_task(). A typical race condition is illustrated below: CPU 0 (cleanup) | CPU 1 (delayed work callback) cnic_netdev_event() | cnic_stop_hw() | cnic_delete_task() cnic_cm_stop_bnx2x_hw() | ... cancel_delayed_work() | /* the queue_delayed_work() flush_workqueue() | executes after flush_workqueue()*/ | queue_delayed_work() cnic_free_dev(dev)//free | cnic_delete_task() //new instance | dev = cp->dev; //use Replace cancel_delayed_work() with cancel_delayed_work_sync() to ensure that the cyclic delayed work item is properly canceled and that any ongoing execution of the work item completes before the cnic_dev is deallocated. Furthermore, since cancel_delayed_work_sync() uses __flush_work(work, true) to synchronously wait for any currently executing instance of the work item to finish, the flush_workqueue() becomes redundant and should be removed. This bug was identified through static analysis. To reproduce the issue and validate the fix, I simulated the cnic PCI device in QEMU and introduced intentional delays — such as inserting calls to ssleep() within the cnic_delete_task() function — to increase the likelihood of triggering the bug. | Oct 4, 2025 |

Schematically we can have something like this: CPU0 CPU1 zram_slot_lock() zs_free(handle) zram_slot_lock() zram_slot_lock() zs_free(handle) zram_slot_lock() compress compress handle = zs_malloc() handle = zs_malloc() zram_slot_lock zram_set_handle(handle) zram_slot_lock zram_slot_lock zram_set_handle(handle) zram_slot_lock Either CPU0 or CPU1 zsmalloc handle will leak because zs_free() is done too early. In fact, we need to reset zram entry right before we set its new handle, all under the same slot lock scope. | Oct 4, 2025 |
| CVE-2025-39939(opens NVD record) | High | 7.8 | In the Linux kernel, the following vulnerability has been resolved: iommu/s390: Fix memory corruption when using identity domain zpci_get_iommu_ctrs() returns counter information to be reported as part of device statistics; these counters are stored as part of the s390_domain. The problem, however, is that the identity domain is not backed by an s390_domain and so the conversion via to_s390_domain() yields a bad address that is zero'd initially and read on-demand later via a sysfs read. These counters aren't necessary for the identity domain; just return NULL in this case. This issue was discovered via KASAN with reports that look like: BUG: KASAN: global-out-of-bounds in zpci_fmb_enable_device when using the identity domain for a device on s390. | Oct 4, 2025 |

| CVE-2023-53506(opens NVD record) | High | 7.8 | In the Linux kernel, the following vulnerability has been resolved: udf: Do not bother merging very long extents When merging very long extents we try to push as much length as possible to the first extent. However this is unnecessarily complicated and not really worth the trouble. Furthermore there was a bug in the logic resulting in corrupting extents in the file as syzbot reproducer shows. So just don't bother with the merging of extents that are too long together. | Oct 1, 2025 |
