CVE-2026-74684

A flaw was found in the Linux kernel's net: tap module. A NULL pointer dereference can occur in the tapgetuserxdp function when processing an XDP buffer with a GSO virtio-net header and a zero protocol. This can be triggered by a malicious guest in a virtualized environment, leading to a system...

CVE-2026-74627

A flaw was found in the Linux kernel's net: devmem component. This vulnerability occurs when netiov and page-backed fragments are improperly mixed within a single skb socket buffer in the zerocopyfillskbfromdevmem function. This improper handling can lead to a system crash, resulting in a Denial ...

CVE-2026-74620

A flaw was found in the Linux kernel's net/sched subsystem, specifically within the actgact and actpolice modules. A local user could exploit this vulnerability by providing a specially crafted control action that bypasses proper range checks. This improper handling of control actions leads to an...

CVE-2026-74692

A flaw was found in the Linux kernel's net/smc component. A time-of-check to time-of-use TOCTOU race condition allows a remote attacker to exploit a window where the listener's state is checked without proper locking. By opening TCP connections while the server is closing, an attacker can cause a...

Tracking PavinLoader across ClickFix and fake download campaigns

In our previous analysis of the malicious RenPy campaigns, we identified a multi-stage loader deployed as part of the infection chain. Further threat hunting has since shown that the same loader, which we track as PavinLoader , is being used across several different campaigns, including ClickFix...

CVE-2026-74717

A flaw was found in the Linux kernel's net/mlx5 component. This vulnerability occurs because the firmware tracer fwtracer does not properly handle error return values, specifically when ERRPTR is returned instead of NULL. An attacker could potentially trigger a kernel panic by exploiting this...
