CVE-2026-68442

CVE-2026-68442 describes a Linux kernel btrfs bug where splitting extent maps incorrectly propagates EXTENT_FLAG_LOGGING to new split maps. The local flags copy was used for splits, while a later change cleared the flag on em->flags, so a split map being logged could be freed with the flag sti...

CVE-2026-68442

In the Linux kernel, the following vulnerability has been resolved: btrfs: don't propagate EXTENTFLAGLOGGING to split extent maps When btrfsdropextentmaprange splits an extent map, the new split maps inherit the original map's flags through a local 'flags' variable. Commit f86f7a75e2fb "btrfs: us...

Panic-safety unsoundness in `SplitVec::extend_from_slice` (uninitialized read)

SplitVec::extendfromslice increments the logical length self.len before cloning the incoming elements into the reserved slots. If an element's Clone panics mid-fill, unwinding leaves self.len counting slots that were never initialized. A later safe read get, indexing, iter then reads one of those...

CVE-2026-68163

In the Linux kernel, the following vulnerability has been resolved: mm/pagevmamapped: fix device-private PMD handling Commit 65edfda6f3f2 "mm/rmap: extend rmap and migration support device-private entries" introduced the concept of device-private PMD entries, but did not correctly update the rmap...

CVE-2026-68163

The CVE-2026-68163 entry concerns Linux kernel memory management: device-private PMD handling in page_vma_mapped_walk() and related code paths. Root cause was improper handling of device-private PMD entries after adding device-private support, leading to cases where PMD entries with PFNs could be...

kernel: xen/privcmd: fix double free via VMA splitting

A flaw was found in the Linux kernel's xen/privcmd module. A local user could exploit this by performing a partial unmapping of a privcmd memory region. This action causes a Virtual Memory Area VMA to split, leading to duplicated internal memory pointers. As a result, the same memory can be freed...

GitPython: Unsafe git option guard bypass via split_single_char_options=False short-option token smuggling enables command execution

Summary The checkunsafeoptions guard can be bypassed on every guarded method clone/clonefrom, fetch/pull/push, lsremote, itercommits, blame, archive by combining a single-character kwarg with splitsinglecharoptions=False. The guard's candidate list omits the smuggled option, but transformkwarg...

GHSA-J4R3-HG7J-8CHG node-re2: Out-of-bounds heap read in `replace`/`split` via a `Buffer` ending in a truncated multi-byte UTF-8 character → adjacent heap memory disclosed to JavaScript

Summary re2 infers a character's byte length from its UTF-8 lead byte alone, with no bound on the bytes actually remaining in the input. Buffer arguments reach the native layer verbatim — only strings are re-encoded into well-formed UTF-8 — so a Buffer whose last byte is a multi-byte lead promise...
