CVE-2026-43863 LOW PATCH Monitor

Mutt before version 2.3.2 contains an infinite loop in the data_object_to_stream function within crypt-gpgme.c that can be triggered during GPG encryption operations, leading to denial of service. The vulnerability affects remote attackers under high-complexity conditions (requiring specific GPG-encrypted message handling), and is publicly documented via a GitHub commit but has no active exploitation confirmed. The fix changes the loop condition from checking non-zero read results to explicitly checking for positive read values (> 0), preventing infinite iteration when gpgme_data_read returns zero or negative values.

CVE-2026-35340 Cargo MEDIUM PATCH This Month

uutils coreutils chown and chgrp utilities return incorrect exit codes during recursive directory operations, masking ownership change failures and allowing administrative scripts to incorrectly assume successful permission transfers. When processing multiple files recursively, the final exit code reflects only the last file's result; if that file succeeds, the command returns 0 even if earlier operations failed due to permission errors. This integrity flaw affects local users with limited privileges on systems running affected versions below 0.6.0, creating risk of security misconfigurations in automated deployment and configuration management scripts.

CVE-2026-35339 Cargo MEDIUM PATCH This Month

The chmod utility in uutils coreutils versions prior to 0.6.0 incorrectly reports success (exit code 0) when recursively processing multiple files, even if permission changes fail on earlier files due to access restrictions or other errors. This causes scripts and automation to proceed under a false assumption that all files were modified correctly, potentially leaving sensitive files with unintended or restrictive permissions.

CVE-2026-35091 HIGH PATCH This Week

Out-of-bounds read in Corosync allows unauthenticated remote attackers to crash cluster nodes and potentially leak memory via malformed UDP packets. Affects default totemudp/totemudpu configurations across Red Hat Enterprise Linux 7/8/9/10 and OpenShift Container Platform 4. CVSS 8.2 (High) with network attack vector, low complexity, and no authentication required. EPSS and exploitation status data not available; no public exploit identified at time of analysis. Impacts high-availability clustering infrastructure commonly used in enterprise production environments.

CVE-2026-0648 HIGH This Week

Memory corruption in ThreadX RTOS CreateCounter() function allows local attackers with user privileges to trigger hard faults or corrupt kernel memory by exhausting the counter pool, which causes an unchecked error code to be cast as a wild pointer. The vulnerability stems from incorrect error validation logic that fails to detect counter allocation failures, enabling subsequent writes to arbitrary memory addresses. No patch is currently available.
