CVE-2023-54121
In the Linux kernel, the following vulnerability has been resolved: btrfs: fix incorrect splitting in btrfsdropextentmaprange In production we were seeing a variety of WARNON's in the extentmap code, specifically in btrfsdropextentmaprange when we have to call addextentmapping for our second spli...
CVE-2023-54123
In the Linux kernel, the following vulnerability has been resolved: md/raid10: fix memleak for 'conf-biosplit' In the error path of raid10run, 'conf' need be freed, however, 'conf-biosplit' is missed and memory will be leaked. Since there are 3 places to free 'conf', factor out a helper to fix th...

CVE-2023-54123
The CVE-2023-54123 issue is in the Linux kernel md/raid10 path where, in the error path of raid10_run(), conf is freed but conf->bio_split is not, causing a memory leak. The root cause was that memory allocated for conf->bio_split was not freed in all error-handling paths; three exit points...

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
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...
