#Copyfail
Il faut que je demande au RH de rajouter un champ CVE sur mes formulaires de congés.

2 jours avants mes précédents c'était Copyfail. Là on se tape PwnEscape et Php2Shell.

(spoiler: préparez-vous à patcher un truc fin janvier 😅)

InfraTrust flags active attacks on network management systems, with RCE flaws in Cisco FMC, ISE, SonicWall SMA 1000, and Check Point products. Linux CopyFail and firmware bugs widen supply-chain risk. #Cisco #SonicWall #CheckPoint
InfraTrust Report Warns Network Management Systems Under Attack
Attackers are increasingly targeting infrastructure management systems, with exploited flaws in Cisco Secure Firewall Management Center, Cisco Identity Services Engine, SonicWall SMA 1000, and Check Point products enabling remote code execution and full device control. The report also highlights widespread supply-chain impact from the Linux kernel "CopyFail" flaw and firmware weaknesses affecting Cisco, AMI Aptio-based systems, and Insyde. #Cisco #SonicWall #CheckPoint #Arista #CopyFail #CyclopsBlink #Sandworm #Qilin

Linux Detection Engineering for LPE: a layered Linux escalation framework pairs root-transition logic with rules for SUID abuse, unshare, Python exploits, and page-cache corruption, with Elastic Defend and Auditd coverage. #LinuxLPE #ElasticDefend
Linux Detection Engineering - Local Privilege Escalation
The article describes a layered Linux privilege escalation detection framework that combines general root-transition logic with technique-specific rules for SUID abuse, unshare, Python-driven exploits, and kernel page-cache corruption. It also reviews 2026 Linux LPE cases such as Copy Fail, DirtyFrag, Fragnesia, DirtyDecrypt, pedit COW, DirtyClone, CIFSwitch, OVSwrap, and CVE-2026-46333, showing how Elastic Defend and Auditd can catch them in practice. #CopyFail #DirtyFrag #Fragnesia #DirtyDecrypt #peditCOW #DirtyClone #CIFSwitch #OVSwrap #CVE-2026-46333

Just playing with dirtyfrag mitigations and patches, and it seems `drop_caches` is broken in linux in a way that it does NOT remove a poinsoned page cache

# echo 3 > /proc/sys/vm/drop_caches
# su - games
# id
uid=0(root) gid=0(root) groups=0(root)

thanks, copyfail! now I can update my root password that I forgot on a server where I don't have GRUB access!

Linux systems face a new root escalation threat called "Dirty Frag," which chains two vulnerabilities (CVE-2026-43284 and CVE-2026-43500) to overwrite read-only page cache data in memory. The flaws al...

Yeah, I saw a Lotta panic about copyfail and I felt it was way overblown, its just models are good enough now to find these and Linux can't bury security flaws like MS has been trying to do.

As you say, the pace will slow, there's a finite number of security flaws in all these systems.

CopyFail対応したいんだけど…

There's apparently another Linux LPE.
DirtyDecrypt, also known as DirtyCBC, is a variant of CopyFail / DirtyFrag / Fragnesia.
I suspect it may be CVE-2026-31635.

I have not been able to get it to actually work on **any** Linux distro that I've tried.

While it's raining Linux LPEs, I suppose it's worth mentioning Copy Fail 2:Electric Boogaloo

Unlike CopyFail, this one works against Ubuntu 26.04, as it was only patched a few days ago
May 8, 2026 at 12:05 AM
This one also affects Fedora 44, which was immune to CopyFail by way of using a recent kernel.
