CVE Vulnerability Catalog

In the Linux kernel, in the L2TP subsystem, a possible tunnel refcount underflow was fixed, which could occur during session deletion when the tunnel pointer was invalid.

The openTempFile function in Xpdf and Poppler 0.24.3 and earlier creates temporary files with predictable names when running on non-Unix systems. A local user can exploit a symlink attack to overwrite arbitrary files.

In the Linux kernel, a proper folio cleanup was fixed in Btrfs when cow_file_range() fails. The issue involved improper handling of dirty pages.

In the Linux kernel, in the Bluetooth subsystem (MGMT), possible deadlocks were fixed that could occur due to hci_cmd_sync_dequeue, causing threads to block for extended periods.

In the Linux kernel, in the DRM/XE driver (guc_submit), a race condition around the suspend_pending field was fixed, which could cause assertions and warnings in certain test scenarios.

In the Linux kernel, the Bluetooth subsystem (hci_core) now disables works during hci_unregister_dev because the hci_dev is about to be freed and new submissions should not be allowed.

In the Linux kernel's drm/amdgpu/mes driver, a use-after-free issue exists. The fix removes the fence fallback timer to eliminate random errors.

In the Linux kernel, in the RDMA/hns driver, a soft lockup issue under heavy CEQE load was fixed by moving CEQE handling to the BH (bottom half) context.

In the Linux kernel, in the NFS server (nfsd), a race between the laundromat thread and the free_stateid operation was fixed, which could lead to incorrect handling of expired delegations.

In the Linux kernel, a double accounting race was fixed in Btrfs when btrfs_run_delalloc_range() fails. The issue occurs when block size is smaller than page size and can lead to kernel crash.

In the Linux kernel, in the Bluetooth subsystem (hci_conn), the function disable_delayed_work_sync is used instead of cancel_delayed_work_sync, which not only cancels ongoing work but also disables new submissions, which is desirable.

In the Linux kernel, a race condition was fixed in the OA TC6 network driver between reference pointers for TX packets. The issue involves managing two skb pointers for packets enqueued from the network stack.

The ReadPCXImage function in coders/pcx.c in ImageMagick 7.0.4.9 allows remote attackers to cause a denial of service (attempted large memory allocation and application crash) via a crafted file. This vulnerability exists because of an incomplete fix for CVE-2016-8862 and CVE-2016-8866.

The WritePICONImage function in coders/xpm.c in ImageMagick 7.0.6-4 allows remote attackers to cause a denial of service (memory leak) via a crafted file that is mishandled in an OpenPixelCache call.

ImageMagick prior to versions 6.9.13-27 and 7.1.2-1 has undefined behavior (function-type-mismatch) in the splay tree cloning callback. This results in a deterministic abort under UBSan (DoS in sanitizer builds).

In the Linux kernel, the drm/amdgpu driver changed the handling of the vm->task_info object. The object is now dynamically allocated and reference-counted, improving safety and stability.

In the Linux kernel, the Android Binder driver no longer stores a pointer to a VMA for later use outside the mmap_lock. This was unsafe because the pointer could reference freed memory.

In the Linux kernel, a vulnerability was found in the tracing mechanism where trace_event_file lacks reference counters. This can lead to use-after-free and kernel crash.

GNU binutils gold w wersjach od 1.11 do 1.16 (GNU binutils w wersjach od 2.21 do 2.31.1) jest podatny na niewłaściwą walidację danych wejściowych, porównania podpisane/niepodpisane oraz odczyty poza zakresem. Wpływ tej podatności może prowadzić do odmowy usługi.

W PHP 7.x przed 2017-03-07 występuje błąd w analizie wywołań fsockopen, który może prowadzić do nieprawidłowego interpretowania adresów i portów. Na przykład, wywołanie fsockopen('127.0.0.1:80', 443) może być zinterpretowane jako 127.0.0.1:80:443, co później jest skracane do 127.0.0.1:80.
