kernel: perf: Fix use-after-free when perf mmap() revival races with the last munmap()
A flaw was found in the Linux kernel's perf subsystem. A race condition exists between the perf mmap revival and the last munmap operation. This allows a local unprivileged user to exploit a use-after-free vulnerability, leading to local privilege escalation to root...
kernel: ALSA: seq: close a re-opened queue timer in the destructor
A flaw was found in the Linux kernel's ALSA Advanced Linux Sound Architecture sequencer component. An unprivileged local user with access to the sound device can exploit a timing window during the cleanup of a queue timer. This allows the user to re-open a timer that has already been closed,...
kernel: drm/dp/mst: fix buffer overflows in sideband chunk accumulation
A flaw was found in the Linux kernel's DisplayPort DP Multi-Stream Transport MST subsystem. This vulnerability involves multiple buffer overflows within the drmdpsidebandappendpayload function when handling data from connected devices. A physically connected, malicious DP MST device can exploit...
kernel: drm/vmwgfx: use check_add_overflow for shader size+offset bound
A flaw was found in the drm/vmwgfx component of the Linux kernel. An integer overflow vulnerability exists in the vmwshaderdefine function due to improper validation of user-supplied shader window size and offset. When the offset value is close to its maximum, an unsigned addition can wrap around...
kernel: perf: Fix addr_filter_ranges lifetime
A flaw was found in the Linux kernel's performance events perf subsystem. This vulnerability occurs because memory allocated for event address filters is released prematurely while still in active use by other kernel processes. A local user could exploit this use-after-free flaw during performanc...
kernel: ipv4: raw: reject IP_HDRINCL packets with ihl < 5
A flaw was found in the Linux kernel's handling of IPv4 raw sockets. An unprivileged attacker with CAPNETRAW capabilities can craft and inject a malformed IPv4 packet with an invalid Internet Header Length IHL. This can lead to an out-of-bounds memory access when the packet is processed by certai...
kernel: drm/amdkfd: Add TLB flush after MES queue eviction/suspension
A flaw was found in the Linux kernel's drm/amdkfd component. This vulnerability arises from a race condition where the Micro Engine Scheduler MES fails to perform a necessary Translation Lookaside Buffer TLB invalidation after unmapping queues. This oversight allows in-flight Direct Memory Access...
kernel: drm/amd/display: set new_stream to NULL after release
A flaw was found in the Linux kernel's drm/amd/display component. Specifically, within the dmupdatecrtcstate function, a stream pointer is released but not subsequently set to NULL. This can lead to a double release of the same pointer if an error occurs later in the process, creating a...
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:...

rootpacket-cve-2026-31431
rootpacket CVE-2026-31431 A Linux Docker-to-host cryptojacking toolkit captured from live attacks on Kinryū Labs honeypots. It breaks in through an exposed Docker Engine API, escapes the container to root the host with CVE-2026-31431 , installs a kernel rootkit, and runs an XMRig Monero miner. Fu...
CVE-2026-98728
A flaw was found in the Linux kernel's Trusted Platform Module TPM driver. This flaw can lead to information disclosure when the kernel requests random data. Due to an incorrect bounds check when processing session-tagged responses, a truncated response can pass validation and cause the kernel to...
CVE-2026-98726
A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express multipath subsystem. A malicious NVMe device can provide crafted Asymmetric Namespace Access ANA log data that triggers an integer underflow during buffer bounds validation. This failure leads to an out-of-bounds memory read,...
CVE-2026-98730
A flaw was found in the Linux kernel's Intel Bluetooth PCIe driver. A local user with access to the Bluetooth Host Controller Interface HCI user channel can inject an oversized transmission packet. Because the driver fails to validate packet length before copying data into a fixed-size memory...
CVE-2026-98727
A flaw was found in the Linux kernel's NVMe Non-Volatile Memory Express multipath subsystem. The multipath driver inappropriately marks a storage device as supporting zoned storage before confirming its zone configuration. When a device reports a zone size of zero, subsequent read or write...
CVE-2026-98729
A flaw was found in the Linux kernel. On systems utilizing specific AMD processors, improper virtual address alignment for huge page memory mappings can allow a local user to cause a Denial of Service DoS. When unmapping these misaligned memory ranges during teardown, the kernel encounters an...
