CVE-2026-98342

A flaw was found in the Linux kernel's Direct Memory Access DMA engine subsystem. A timing flaw allows a device structure to be freed from memory while active read operations are still referencing it. A local attacker could exploit this use-after-free race condition to cause a Denial of Service D...

CVE-2026-98341

A flaw was found in the Linux kernel's cfg80211 wireless subsystem. When a wireless network interface is shut down while an active scan is running, the kernel prematurely frees memory associated with the scan request while the driver is still accessing it. A local user could exploit this race...

CVE-2025-40019-Essiv

CVE-2025-40019-Essiv A PoC for CVE-2025-40019 in ESSIV module. exploit WIP for exploitation, note that scatterlist both req-src and req-dst has pagelink member. pagelink is a way to encode sg table info alongside page pointer as far as I understand: gdb ptype struct scatterlist type = struct...

CVE-2026-98339

A flaw was found in the Linux kernel's cfg80211 wireless subsystem. This flaw allows a nearby attacker operating a rogue wireless access point to cause a Denial of Service DoS. When an access point changes channels, stale Basic Service Set BSS network entries may fail to be removed if unexpected...

CVE-2026-98338

A flaw was found in the Linux kernel's cfg80211 wireless subsystem. A race condition occurs during Independent Basic Service Set IBSS, an ad-hoc wireless network join event handling because the kernel does not hold an active reference to the service set entry before processing the event. A local...

CVE-2026-98337

A flaw was found in the Linux kernel's mac80211 wireless subsystem. A local user can cause a Denial of Service DoS or system instability by initiating a remain-on-channel ROC operation while a wireless network scan is concurrently active. This race condition leads to improper state handling and...

CVE-2026-98336

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. A local user with network administration privileges can cause a denial of service DoS by configuring hardware traffic control TC offloading on virtual Access Point Virtual Local Area Network APVLAN interfaces. Because...

CVE-2026-98335

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. When a wireless interface disconnects from a mesh network while a channel switch announcement is in progress, the system releases the channel context without properly canceling the ongoing switch operation. A local use...

CVE-2026-98334

A flaw was found in the Linux kernel's mac80211 wireless subsystem. When starting a wireless Access Point AP fails after setting beacon parameters, the kernel does not properly reset its internal state. A local attacker can exploit this condition by triggering subsequent scanning operations on th...

CVE-2021-3493

CVE-2021-3493 Ubuntu OverlayFS Local Privesc Affected Versions Ubuntu 20.10 Ubuntu 20.04 LTS Ubuntu 19.04 Ubuntu 18.04 LTS Ubuntu 16.04 LTS Ubuntu 14.04 ESM Usage gcc exploit.c -o exploit ./exploit Description "Ubuntu specific issue in the overlayfs file system in the Linux kernel where it did no...

CVE-2026-98333

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. When bringing up a wireless interface fails, the system does not reset the radio LED state, leaving an internal throughput timer running. Consequently, when the wireless device is subsequently removed or unregistered,...

CVE-2026-98331

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. When a network namespace hosting a wireless device is destroyed, memory allocation failures during device migration can leave unregistered network interfaces in internal tracking lists. A local user can exploit this...

CVE-2026-98330

A flaw was found in the Linux kernel's cfg80211 wireless subsystem. When a network namespace is destroyed, the subsystem attempts to move wireless devices back to the default namespace, but a failure during the transfer can leave behind an invalid namespace reference. A local attacker can exploit...

CVE-2026-98329

A flaw was found in the Linux kernel's mac80211 wireless networking subsystem. When packets are injected on a monitor network interface, mac80211 does not verify whether the bandwidth requested in the radiotap header exceeds the operational channel bandwidth before forwarding it to the driver. A...

CVE-2026-98328

A flaw was found in the Linux kernel's mac80211 wireless subsystem. This flaw allows a local user to cause a Denial of Service DoS by initiating a wireless scan on a device supporting 6 GHz High Efficiency HE bands. Because the kernel fails to account for the HE 6 GHz capability element when...

CVE-2026-98327

A flaw was found in the Linux kernel's mac80211 wireless mesh networking subsystem. When leaving or stopping a mesh network while a Channel Switch Announcement CSA is still pending, the kernel fails to reset the switch state and release allocated memory. A local privileged user could exploit this...

CVE-2026-98324

A flaw was found in the Linux kernel's PXA Direct Memory Access DMA driver. A local user could trigger a Denial of Service DoS or memory corruption due to descriptor double-counting during allocation. When processing hardware descriptors, the driver incorrectly increments the descriptor counter,...

Dirty-Pipe-Exploit

Dirty-Pipe-Exploit The Dirty Pipe exploit CVE-2022-0847 is a Linux kernel vulnerability v5.8+ allowing unprivileged attackers to overwrite arbitrary files via a flaw in the pipe mechanism. This leads to privilege escalation, granting root access. Similar to Dirty Cow but easier to exploit. Fix:...
