fil-c

Fil-C 0.686 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-2025-14174-Chrome-Zero-Day

Affected Software: Google Chrome prior to version 121.0.6167.85. Vulnerability Type: Use‑after‑free in the V8 JavaScript engine. Description: A use‑after‑free bug in V8’s garbage collection allows crafted JavaScript to corrupt memory, leading to arbitrary code execution within the browser context...

CVE-2026-98289

A flaw was found in the Linux kernel's UNIX domain socket afunix subsystem. A logic error in the socket garbage collection algorithm can prevent cyclical socket references from being properly identified and reclaimed. A local user could exploit this flaw to cause a resource leak, potentially...

CVE-2026-98289

The Linux kernel contains a vulnerability in the af_unix component related to how Tarjan's algorithm handles SCC (Strongly Connected Component) indices. Specifically, the unix_vertex_dead() function assumes all vertices in an SCC share the same lowpoint (scc_index), but this assumption fails if a...

CVE-2026-98289: Undefined Security Weakness

A read-after-free memory flaw was found in the Linux kernel's garbage collection

A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close and fget simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: f2fs: fixed the sanity check on summary information As Wenqing Liu reported in bugzilla: https://bugzilla.kernel.org/showbug.cgi?id=216456 BUG: KASAN: use-after-free in recoverdata+0x63ae/0x6ae0 f2fs Read of size 4 at addr...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: afunix: Fixed the garbage collector’s race condition with connect The garbage collector does not consider the risk of an “embryo” being enqueued during garbage collection. If such an “embryo” has a peer that carries SCMRIGHTS, tw...

In the Linux kernel, the following vulnerabilities have been resolved: netfilter: nftables: The backend for setting up DEAD bits was changed to use the GC transaction API. The old and buggy gc API and the busy mark approach have been replaced with the GC transaction API. No set elements are remov...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: afunix: Initialize sccindex in unixaddedge. Quang Le reported that the AFUNIX GC could garbage-collect a receive queue of an alive in-flight socket, with a detailed repro. The repro consists of three stages. 1 Create a single...

Astra Linux – Vulnerability in Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: f2fs: A sanity check was added for the F2FSInlineDATA flag in the inode during garbage collection GC.
