CVE-2023-54121

CVE-2023-54121 affects the Linux kernel's btrfs extent_map handling. The bug in btrfs_drop_extent_map_range can miscalculate the length when skipping a pinned extent, leading to a faulty split of the next extent and creating an invalid extent_map that may overlap other entries and disrupt block c...

CVE-2025-68329

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix WARNON in tracingbuffersmmapclose for split VMAs When a VMA is split e.g., by partial munmap or MAPFIXED, the kernel calls vmops-close on each portion. For trace buffer mappings, this results in ringbufferunmap being...

CVE-2025-68329 tracing: Fix WARN_ON in tracing_buffers_mmap_close for split VMAs

In the Linux kernel, the following vulnerability has been resolved: tracing: Fix WARNON in tracingbuffersmmapclose for split VMAs When a VMA is split e.g., by partial munmap or MAPFIXED, the kernel calls vmops-close on each portion. For trace buffer mappings, this results in ringbufferunmap being...

CVE-2025-68329

The CVE-2025-68329 entry documents a Linux kernel issue in tracing: when a VMA is split, the kernel could invoke ring_buffer_unmap multiple times (due to multiple vm_ops->close calls) while ring_buffer_map was called once, causing ring_buffer_unmap to return -ENODEV and triggering a WARN_ON. T...
