CVE-2026-84309

A flaw was found in pypdf. An attacker can craft a malicious PDF document with a cyclic tree structure. When a writing code path attempts to insert a child object, the TreeObject.insertchild function can follow /Next links indefinitely, leading to an infinite loop. This can result in a denial of...

The X-mount.subdir option uses a detached-tree fast path on Linux 6.15 and later and passes the configured subdirectory to opentree with ATSYMLINKNOFOLLOW. That flag does not stop intermediate symlink traversal or keep resolution inside the newly mounted filesystem. A local unprivileged user with...

In the Linux kernel, the following vulnerability has been resolved: afs: Fix the volume AFSVOLUMERMTREE is set on Fix afsinsertvolumeintocell to set AFSVOLUMERMTREE on the volume replaced, not the new volume, as it's now removed from the cell's volume tree. This will cause the old volume to be...

CVE-2026-84309

pypdf is a free and open-source pure-python PDF library. Prior to 6.16.0, an attacker can craft a PDF whose cyclic tree structure causes pypdf/generic/datastructures.py TreeObject.insertchild to follow /Next links indefinitely when a writing code path inserts a child, producing an infinite loop...

CVE-2026-46603

A flaw was found in golang.org/x/image/vp8l. A remote attacker can cause a denial of service by providing a specially crafted VP8L image. This image, containing many unused Huffman tree groups, leads to excessive memory allocation during VP8L decoding, resulting in memory exhaustion. Mitigation...

CVE-2026-80638

A flaw was found in the ocfs2 component of the Linux kernel. When a user unlinks a refcounted file whose refcount tree has leaf blocks, an out-of-bounds write occurs within the ocfs2removerefcountextent function. This happens because a memset operation writes past the intended memory boundary due...
