fil-c

Fil-C 0.684 Fil-C is a fanatically compatible memory-safe implementation of C and C++. Lots of software compiles and runs with Fil-C with zero or minimal changes. All memory safety errors are caught as Fil-C panics. Fil-C achieves this using a combination of concurrent garbage collection and...

CVE-2026-80668

In the Linux kernel, the following vulnerability has been resolved: netfilter: nfconntrackexpect: use conntrack GC to reap expectations This patch replaces the timer API by GC worker approach for expectations, as it already happened in many other subsystems. Use the existing conntrack GC worker t...

CVE-2026-74746

A flaw was found in the netfilter flowtable component of the Linux kernel. This vulnerability occurs due to a timing issue where the system's garbage collection can free a network flow while it is still being set up. This can lead to a 'use-after-free' condition, where the system attempts to acce...

CVE-2026-80521

A flaw was found in the Linux kernel's afunix component. A race condition during concurrent send and close operations can lead to the garbage collector GC partially freeing a Strongly Connected Component SCC. This inconsistent state may cause subsequent GC operations to iterate over a partially...

CVE-2026-74748

A flaw was found in the Linux kernel's netfilter ipset component. A race condition exists between the list:set garbage collection and set swap operations. This concurrency issue can lead to a kernel bug and a system crash, effectively causing a denial of service. This vulnerability can be trigger...
