CVE-2025-71184

CVE-2025-71184 affects the Linux kernel’s btrfs subsystem. The issue is a NULL dereference in btrfs_evict_inode() when tracing inode eviction because the root may be NULL. The fix ensures root is treated as 0 or delays tracing until the root is non-NULL, preventing a NULL dereference during evict...

Denial-of-service (DoS)

pypdf is vulnerable to denial-of-service DoS. The vulnerability is due to improper handling of PDFs missing the /Root object with a large /Size value in non-strict parsing mode, which allows an attacker to craft an invalid PDF that triggers excessively long runtimes...

CVE-2026-22690

pypdf is a free and open-source pure-python PDF library. Prior to version 6.6.0, pypdf has possible long runtimes for missing /Root object with large /Size values. An attacker who uses this vulnerability can craft a PDF which leads to possibly long runtimes for actually invalid files. This can be...
