CVE Vulnerability Catalog

In the Linux kernel's networking subsystem, a dangling sk pointer is left when socket creation fails, potentially leading to use-after-free when __sock_release() is called with an fentry probe.

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, 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, 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, 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, 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, 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, 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.

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, 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, 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, an overflow in the ring-buffer's __rb_map_vma function was fixed, which occurred when calculating the number of pages (nr_pages). A check was added before the calculation to avoid the issue.

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.

A vulnerability in libfuse versions 3.18.0 through 3.18.1 causes a NULL pointer dereference and memory leak in the fuse_uring_init_queue function. A local user can exploit this to crash the FUSE daemon or exhaust system resources.

In the Linux kernel, a vulnerability was found in the mechanism preventing timer interrupt starvation. Missing resets of the next_event_forced flag in several places, such as when the clock event state changes, may cause incorrect behavior.

In the Linux kernel, a vulnerability in KVM for AMD SEV-SNP was found. During SNP launch finish, the synchronization and encryption of VMSA (Virtual Machine Save Area) does not lock all vCPUs, allowing userspace to manipulate or run a vCPU while its state is being synchronized.

In NTFS-3G through version 2026.2.25, a heap buffer overflow exists in the ntfs_ib_copy_tail() function in libntfs-3g/index.c. This vulnerability allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image.

In NTFS-3G through version 2026.2.25, a heap buffer overflow in ntfs_index_walk_down() in libntfs-3g/index.c allows an attacker to corrupt heap memory in the SUID-root ntfs-3g binary by crafting a malicious NTFS image.

In NTFS-3G through version 2026.2.25, an out-of-bounds read vulnerability exists in the ntfs_fix_file_name() function in libntfs-3g/reparse.c. An attacker can exploit this by crafting a malicious NTFS image, leading to the disclosure of confidential information from ntfs-3g process memory when a readlink is performed on a corrupted reparse point.
