CVE Vulnerability Catalog

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.

The decNumberCopy function in decNumber.c in jq through 1.7.1 does not properly consider that NaN is interpreted as numeric, which has a resultant stack-based buffer overflow and out-of-bounds write. This can be demonstrated by using --slurp with subtraction, such as a filter of .-. when the input has a certain form.

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, 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, 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.

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, the BPF verifier now checks the changes_pkt_data property for extension programs. It decides whether to invalidate all packet pointers in the current state based on this property.

In the Linux kernel, in the sc16is7xx serial driver, a TX FIFO corruption was fixed that could occur when a packet was received on channel A at almost the same time as a packet was about to be transmitted on channel B.

In the Linux kernel, the BPF verifier now tracks the changes_pkt_data property for global functions. It invalidates packet pointers in the current state after calling certain helpers.

In the Linux kernel, in the Btrfs filesystem, an issue with readahead on the relocation inode was fixed when the filesystem uses a RAID stripe tree (RST), which could cause ENOENT errors.

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

In the Linux kernel, RCU protection was added for the conventional zones bitmap of a disk (conv_zones_bitmap) in the block layer. This prevents invalid memory references during disk revalidation.

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, 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.

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's F2FS filesystem, there is potential corruption when moving a directory, similar to an issue in ext4. The fix addresses this problem.

In the Linux kernel's fork function, a race condition exists between fork and hugetlbfs file operations. The fix defers linking the file VMA until the VMA is fully initialized.

In the Linux kernel's bcachefs filesystem, a missing bounds check in superblock validation could allow out-of-bounds read. The fix adds the missing check.
