CVE-2025-21692-poc

CVE-2025-21692-poc This is code for my exploit of the CVE-2025-21692 ets qdisc vulnerability, which accompanies my writeup. Bear in mind that as specified in the writeup the kernel version was patched to enable the vulnerability, 6.6.75 is not vulnerable without removing the patch, but on older,...

CVE-2026-31694-POC

CVE-2026-31694: FUSE readdir cache out-of-bounds write A missing bounds check in fs/fuse/readdir.c:fuseadddirenttocache. A FUSE server returns a dirent with namelen = 4095, which serializes to a 4120-byte record. The kernel copies it into a single 4096-byte page-cache page and overflows by 24...

CVE-2026-31431-copy-fail

CVE-2026-31431 Copy Fail Exploit Part 1: Theoretical Concept How CVE-2026-31431 Works Instead of the system constantly fetching files directly from the slow physical hard disk—which wastes a lot of time the Linux system creates a temporary copy of the file inside RAM, known as the Page Cache. Thi...

kernel: ip6: vti: Use ip6_tnl.net in vti6_changelink()

A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface vti6 component. An unprivileged local user, particularly within a user namespace, could exploit a vulnerability related to incorrect network namespace handling during the movement of a vti6 tunnel. This issue can lead to a kerne...

kernel: nvmet-auth: reject short AUTH_RECEIVE buffers

A flaw was found in the nvmet-auth component of the Linux kernel. A remote attacker, by sending a specially crafted AUTHRECEIVE buffer to an NVMe-oF NVM Express over Fabrics target with in-band authentication enabled, can trigger a heap out-of-bounds write. This vulnerability arises because the...

kernel: udp: fix potential use-after-free in tunnel segmentation

A flaw was found in the Linux kernel's UDP User Datagram Protocol tunnel segmentation. This vulnerability arises when the system attempts to process network packets, specifically in the skbudptunnelsegment function. An attacker could potentially exploit a use-after-free condition, where the syste...

kernel: xfrm: input: hold netns during deferred transport reinjection

A flaw was found in the Linux kernel's xfrm input component. The transport-mode reinjection process, which handles network packet re-injection, stores a network namespace pointer that must remain valid until a deferred callback completes. However, a missing reference count for the network namespa...

kernel: xfrm: fix stale skb->prev after async crypto steals a GSO segment

A flaw was found in the Linux kernel's xfrm subsystem. This vulnerability arises when asynchronous cryptographic operations incorrectly handle network packet segments, leaving a pointer to memory that has already been released. An attacker could potentially exploit this use-after-free condition t...

kernel: xfrm: policy: fix use-after-free on inexact bin in xfrm_policy_bysel_ctx()

A flaw was found in the Linux kernel. A race condition exists in the xfrm policy handling, specifically within the xfrmpolicybyselctx function. This flaw allows for a use-after-free vulnerability, where memory is accessed after it has been released. This can lead to system instability or a denial...

kernel: xfrm: hold dev ref until after transport_finish NF_HOOK

A flaw was found in the Linux kernel's xfrm IP eXtensible FRamework subsystem. This vulnerability involves a race condition where a network device's reference is released too early during packet processing after asynchronous cryptography. This premature release can lead to the system attempting t...

kernel: ip6: vti: Use ip6_tnl.net in vti6_siocdevprivate()

A flaw was found in the Linux kernel's IPv6 Virtual Tunnel Interface VTI module. When a VTI tunnel device is moved to a different network environment, an unprivileged user in a separate user space can manipulate tunnel parameters. This manipulation could allow the user to intercept or redirect...
