CVE-2026-41312 pypdf: Manipulated FlateDecode predictor parameters can exhaust RAM

pypdf is a free and open-source pure-python PDF library. An attacker who uses a vulnerability present in versions prior to 6.10.2 can craft a PDF which leads to the RAM being exhausted. This requires accessing a stream compressed using /FlateDecode with a /Predictor unequal 1 and large predictor...

CVE-2026-41312

CVE-2026-41312 affects the pypdf Python library. Versions prior to 6.10.2 are vulnerable where an attacker can craft a PDF containing a /FlateDecode stream with a /Predictor not equal to 1 and large predictor parameters, causing RAM exhaustion (local access; potential DoS). Affects pypdf’s handli...

CVE-2026-31465

A flaw was found in the Linux kernel. This vulnerability occurs in the writeback mechanism, specifically when handling filesystems that do not guarantee data persistence on synchronization sync operations, such as fuse and fuse-overlayfs. Under certain conditions, like during a suspend-to-RAM eve...

EUVD-2026-24809

In the Linux kernel, the following vulnerability has been resolved: writeback: don't block sync for filesystems with no data integrity guarantees Add a SBINODATAINTEGRITY superblock flag for filesystems that cannot guarantee data persistence on sync eg fuse. For superblocks with this flag set, sy...

CVE-2026-31467

CVE-2026-31465

CVE-2026-31465 in the Linux kernel concerns the writeback path for filesystems without data integrity guarantees (e.g., fuse). The fix adds a SB_I_NO_DATA_INTEGRITY superblock flag; when set, sync kicks off writeback of dirty inodes but does not wait for flusher threads to finish. The change move...
