In the complete callback\nems_usb_read_bulk_callback(), the URBs are processed and resubmitted. In\nems_usb_close() the URBs are freed by calling\nusb_kill_anchored_urbs(&dev->rx_submitted).\n\nHowever, this does not take into account that the USB framework unanchors\nthe URB before the complete function is called. This means that once an\nin-URB has been completed, it is no longer anchored and is ultimately not\nreleased in ems_usb_close().\n\nFix the memory leak by anchoring the URB in the\nems_usb_read_bulk_callback() to the dev->rx_submitted anchor.(CVE-2026-23058)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nlocking/rtmutex: Skip remove_waiter() when waiter is not enqueued\n\nsyzbot triggered the following splat in remove_waiter() via\nFUTEX_CMP_REQUEUE_PI:\n\n KASAN: null-ptr-deref in range [0x0000000000000a88-0x0000000000000a8f]\n class_raw_spinlock_constructor\n remove_waiter+0x159/0x1200 kernel/locking/rtmutex.c:1561\n rt_mutex_start_proxy_lock+0x103/0x120\n futex_requeue+0x10e4/0x20d0\n __x64_sys_futex+0x34f/0x4d0\n\ntask_blocks_on_rt_mutex() does not arm the waiter upon deadlock detection,\nleaving waiter->task nil, where 3bfdc63936dd (\"rtmutex: Use waiter::task instead\nof current in remove_waiter()\") made this fatal.\n\nFurthermore, rt_mutex_start_proxy_lock() should not be calling into remove_waiter()\nupon a successfully grabbing the rtmutex. 1a1fb985f2e2 (\"futex: Handle early deadlock\nreturn correctly\"), moved the remove_waiter() out of __rt_mutex_start_proxy_lock()\n(where 'ret' was only ever 0 or < 0) into the wrapper. Tighten this check to\naccount for try_to_take_rt_mutex().(CVE-2026-53163)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nUSB: serial: omninet: fix memory corruption with small endpoint\n\nMake sure that the bulk-out buffers are at least as large as the\nhardcoded transfer size to avoid user-controlled slab corruption should\na malicious device report a smaller endpoint max packet size than\nexpected.(CVE-2026-63928)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nsecurity/keys: fix missed RCU read section on lookup\n\nNicholas Carlini reports that the keyring code calls assoc_array_find()\nin find_key_to_update() without holding the RCU read lock, while the\nassoc_array_gc() code really is designed around removing the node from\nthe tree and then freeing it after an RCU grace-period.\n\nThe regular key handling doesn't see this because holding the keyring\nsemaphore hides any lifetime issues, but the persistent key handling\nuses a different model.\n\nInstead of extending the keyring locking, just do the simple RCU locking\nthat the assoc_array was designed for.(CVE-2026-64015)\n\nIn the Linux kernel, the following vulnerability has been resolved:\n\nxfs: resample the data fork mapping after cycling ILOCK\n\nxfs_reflink_fill_{cow_hole,delalloc} are both presented with an inode,\na data fork mapping, and a cow fork mapping. Unfortunately, these two\nhelpers cycle the ILOCK to grab a transaction, which means that the\nmappings are stale as soon as we reacquire the ILOCK. Currently we\nrefresh the cow fork mapping by re-calling xfs_find_trim_cow_extent, but\nwe don't refresh the data fork mapping beforehand, which means that the\nxfs_bmap_trim_cow in that function queries the refcount btree about the\nwrong physical blocks and returns an inaccurate value in *shared.\n\nIf *shared is now false, the directio write proceeds with a stale data\nfork mapping. Fix this by querying the data fork mapping if the\nsequence counter changes across the ILOCK cycle.(CVE-2026-64600)", "category":"general", "title":"Description" }, { "text":"An update for kernel is now available for openEuler-20.03-LTS-SP4/openEuler-22.03-LTS-SP3/openEuler-24.03-LTS/openEuler-24.03-LTS-SP2.\n\nopenEuler Security has rated this update as having a security impact of critical.
