A use-after-free bug in Linux's KVM hypervisor can be triggered from a guest virtual machine to corrupt the shadow-page state of the host kernel that runs it
DirtyClone: a Linux kernel privilege escalation that silently rewrites executables in memory, leaving no disk trace. Patch now. JFrog Security Research published a working exploit walkthrough on June 25 for CVE-2026-43503 (CVSS score of 8.8), a Linux kernel privilege escalation they call DirtyClone. It’s the fourth vulnerability in the DirtyFrag family, all sharing the same […]
A flaw in the Linux kernel's traffic-control subsystem can let a local unprivileged user gain root on affected systems
DirtyClone is a new Linux kernel privilege escalation in the DirtyFrag family. JFrog Security Research published a working exploit walkthrough for the flaw on June 25, the first public demonstration for this variant
A Linux kernel nf_tables bug lets local users gain root via use-after-free caused by a logic error; patch removes a single “!”. CVE-2026-23111 lives in nf_tables, the Linux kernel’s packet filtering framework. Exodus Intelligence researcher Oliver Sieber found the bug in early 2025 and chained it into a full local privilege escalation. The flaw was […]
Security researchers have published a detailed, working exploit for a Linux kernel use-after-free that lets an unprivileged local user escalate to root and break out of a container
Monday hit like a cron job with anger issues
PinTheft, a recently patched Linux privilege escalation vulnerability, now has a publicly available proof-of-concept (PoC) exploit that allows local attackers to gain root privileges on Arch Linux systems. [...]
Proof-of-concept (PoC) exploit code has now been released for a recently patched security flaw in the Linux kernel that could allow for local privilege escalation (LPE)
A recently patched local privilege escalation vulnerability in the Linux kernel's rxgk module now has a proof-of-concept exploit that allows attackers to gain root access on some Linux systems. [...]
Fresh kernel flaw comes with public exploit code and continues ugly run of highly reliable privilege escalation bugs tied to memory and page-cache handling
Kernel Privilege Escalation Has One Linux Maintainer Contemplating a 'Kill Switch'Back-to-back kernel vulnerabilities in Linux has defenders scrambling to apply defenses in the age of quick turnaround time for hackers to exploit nascent flaws. "Dirty Frag" and "Copy Fail" kernel privilege escalation vulnerabilities became public knowledge within two weeks of each other.
The privilege escalation vulnerability, which is similar to other Linux flaws like Copy Fail and Dirty Pipe, may already be under limited exploitation.
No Patches Yet Available, After Third Party Published Vulnerability DetailsSecurity researchers have discovered a new, critical flaw in the Linux kernel that attackers can exploit to gain root access. No patches are yet available to fix "Dirty Frag," the second new local privilege escalation flaw to be found in two weeks, following the similar "Copy Fail" vulnerability.
Broken disclosure embargo left admins facing a fresh root-level flaw with no CVE
A new Linux zero-day exploit, named Dirty Frag, allows local attackers to gain root privileges on most major Linux distributions with a single command. [...]
Details have emerged about a new, unpatched local privilege escalation (LPE) vulnerability impacting the Linux kernel
Researchers dropped a reliable root exploit and it didn’t sit idle for long
Researchers dropped a reliable root exploit and it didn’t sit idle for long CISA is warning that a newly-disclosed Linux kernel bug dubbed "CopyFail" is already being exploited, just days after researchers dropped a working root-level exploit.…
