CVE-2026-78422

A flaw was found in zbuspolkit. The Subject::newforowner function incorrectly encodes the user ID UID as an unsigned 32-bit integer instead of a signed 32-bit integer when communicating with the PolicyKit polkit authorization framework. This type mismatch causes polkit to disregard the provided U...

CVE-2026-65183

A flaw was found in Apache Tomcat. A Time-of-check Time-of-use TOCTOU race condition exists when creating Unix domain sockets. This vulnerability allows an unauthorized local user to exploit the timing window to gain access to the Unix domain socket. This could lead to information disclosure or...

gzip: gzip: Arbitrary file overwrite via insecure temporary file handling in gzexe utility

A flaw was found in the gzexe utility of GNU gzip. When the mktemp utility is not available, gzexe creates temporary files with predictable names based on the process ID. A local attacker can exploit this by pre-creating a symbolic link to an arbitrary file at the predicted temporary file path...
