CVE-2026-99160

The Linux kernel contains a vulnerability where reading the per_cpu/cpuN/buffer_meta file for a CPU that never came online results in a NULL pointer dereference of cpu_buffer within rbm_start(). This occurs because the files are created for all possible CPUs, while the buffer->buffers[cpu] mem...

CVE-2026-99159

The Linux kernel contains a vulnerability in the ring-buffer component where the rb_meta_subbuf_idx() function can return an index one sub-buffer too high on persistent ring buffers. This occurs because the function's calculation omits the meta header size, causing an incorrect base whenever the ...

CVE-2026-99158

The Linux kernel contains a vulnerability in the ring-buffer component where the ring_buffer_map_get_reader() function incorrectly treats a NULL return from rb_get_reader_page() as an error. This occurs when an mmap reader catches up with a writer that is still committing events; specifically, wr...

CVE-2020-11179-Adreno-Qualcomm-GPU

My independent work from the poc created by P0 researcher Ben Hawkes Original article: https://googleprojectzero.blogspot.com/2020/09/attacking-qualcomm-adreno-gpu.html My goal is to convert his poc to C, and continue where he left off and turn the poc into either a root shell, or a kernel r/w, a...

CVE-2025-21333-POC

CVE-2025-21333-POC Proof of Concept that exploits CVE-2025-21333 in vkrnlintvsp.sys not so reliable see Requirements and Limitations section. Under the References section are located very helpful resources for who wants to play with the exploit. A detailed analysis of the vulnerability and the...

CVE-2026-98894

A flaw was found in the AMD GPU driver within the Linux kernel. When handling overflow conditions in the Common Platform Error Record CPER ring buffer, the driver relies on parsed entry sizes from the buffer contents without verifying that the read pointer advances. Corrupt error record data can...

CVE-2026-98850

A flaw was found in the Linux kernel's packet socket implementation. An integer overflow occurs in the transmission ring buffer when calculating the total byte count of transmitted frames during a send operation. A local user with raw network privileges can exploit this issue to trigger an intern...

Out-of-bounds write in the Brotli decoder ("Node2Shell") also affects the PyPI Brotli package

CVE-2026-111497 "Node2Shell" is an out-of-bounds write CWE-787 in Google'sBrotli decoder c/dec/decode.c. DecodeBlockTypeAndLength returns an ambiguousvalue for an invalid block switch, and the fast decode path discards itCWE-252, unchecked return value, so a crafted Brotli stream makes the...

CVE-2026-80876

A flaw was found in the Linux kernel's ring-buffer component. When 8-byte alignment is enforced, the system incorrectly calculates the length of small events. This error causes these events to report a data length that is 4 bytes larger than their actual size. This discrepancy can lead to...

CVE-2026-80742

A flaw was found in the Linux kernel's afpacket Address Family Packet component. A local attacker could exploit this vulnerability by sending specially crafted zero-byte packets through the TPACKET ring buffer on devices without a hard header. This improper handling of zero-length packets can cau...

CVE-2026-80730

A flaw was found in the Linux kernel. The ring-buffer component's cleanup routine can incorrectly attempt to stop a kernel thread using an invalid error pointer. This happens when kthreadrunoncpu fails, storing an error pointer in the rbthreads array. Calling kthreadstop on this invalid pointer...

CVE-2026-98585

A flaw was found in the Linux kernel's fbnic network driver. A local user with administrative privileges could trigger a denial of service DoS and crash the system by configuring a network ring buffer size of zero. Because the driver fails to validate the input before executing a rounding...

CVE-2026-98503

A flaw was found in the Linux kernel's packet socket implementation. A local user can cause a Denial of Service DoS or system instability by triggering premature reuse of transmit ring buffer slots while packet data is still in flight. Because these shared memory slots may be released and reused...

CVE-2026-90142

A flaw was found in the virtionet component of the Linux kernel. When an AFXDP Address Family eXpress Data Path socket is attached, the system fails to properly resize the RX receive ring buffer. This oversight can lead to an out-of-bounds write operation, where data is written beyond the allocat...
