CVE-2026-31431-Copy-Fail
CVE-2026-31431 - Verification and Mitigation Script This repository documents a Bash script used to assess exposure to CVE-2026-31431 on Linux hosts, with a focus on Ubuntu, and to apply a simple mitigation by blocking the algifaead module. Language versions: English: README.md Portuguese:...
CVE-2016-5195
This record is for learning purposes only; any illegal use is prohibited. Principle The vulnerability works by concurrently flushing dirty pages, causing the content of a file that was originally read-only to be modified. If the modified file is owned by root and has the SUID permission, it can b...
kernel: ipv4: validate checksum_start before completing checksum
A flaw was found in the Linux kernel. A local attacker or untrusted guest virtual machine can exploit this vulnerability by transmitting network packets containing malformed checksum metadata into the IPv4 networking subsystem. This failure to validate checksum metadata can corrupt memory during...
kernel: usb: typec: tcpm: bound altmode_desc[] per iteration in svdm_consume_modes()
A flaw was found in the Linux kernel's USB Type-C Port Manager TCPM driver. A remote attacker, acting as a malicious USB-C port partner, could exploit an out-of-bounds write vulnerability in the svdmconsumemodes function. By sending an unsolicited 'Discover Modes ACK' with excessive data, the...
kernel: Bluetooth: hci_sync: Set HCI_CMD_DRAIN_WORKQUEUE during device close
A flaw was found in the Bluetooth hcisync component of the Linux kernel. When the hcidevclosesync function is called during a device reset, the system may experience queuing timeouts. This occurs because the HCICMDDRAINWORKQUEUE flag is not properly set, which can lead to system instability or a...
kernel: smb: client: fix OOB read/write from unvalidated DataOffset in coalesce_t2()
A flaw was found in the Linux kernel's Server Message Block SMB client. The coalescet2 function processes server-supplied DataOffset fields without proper validation against buffer boundaries. A remote attacker could exploit this by crafting malicious SMB responses. This could lead to out-of-boun...
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: exec: Cleanup POSIX timers right after de_thread()
A flaw was found in the Linux kernel. When a multi-threaded program sets up a per-thread timer and executes a new program that subsequently fails during startup, the kernel can free timer memory while it remains referenced in an active queue. A local user could exploit this vulnerability to trigg...
kernel: openvswitch: defer tunnel netdev_put to RCU release
A flaw was found in the Linux kernel's Open vSwitch OVS component. A race condition can occur during the destruction of a network device netdev tunnel, where the ovsnetdevtunneldestroy function may attempt to release a device reference while other parts of the system are still actively using it...
kernel: USB: serial: mxuport: fix memory corruption with small endpoint
A flaw was found in the Linux kernel's USB serial mxuport driver. A malicious Universal Serial Bus USB device could exploit this vulnerability by reporting a bulk-out endpoint maximum packet size smaller than eight bytes. This can lead to user-controlled slab corruption, potentially allowing an...
kernel: tcp: fix stale per-CPU tcp_tw_isn leak enabling ISN prediction
A flaw was found in the Linux kernel's Transmission Control Protocol TCP networking stack. This vulnerability arises from a stale per-CPU variable that can retain a previously used Initial Sequence Number ISN when certain packets are dropped. A remote attacker could exploit this by sending...
kernel: bridge: mcast: Fix a possible use-after-free when removing a bridge port
A flaw was found in the Linux kernel's bridge multicast functionality. Improper management of multicast contexts when a bridge port is removed can lead to a use-after-free vulnerability. This issue could allow a local attacker to cause a system crash, resulting in a denial of service...
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: inet: frags: strip GSO state from fragments before reassembly
A flaw was found in the Linux kernel's network fragment reassembly process. An unprivileged local user, or a guest in a virtualized environment, could craft specially formed IPv4 or IPv6 network fragments that incorrectly retain Generic Segmentation Offload GSO state after reassembly. This...
PinTheft-go
pintheft-go Go port of pintheft - RDS zcopy double-free LPE. Member of the Dirty Frag vulnerability class. !IMPORTANT Arch Linux is one of the most exposed distributions for this vulnerability, as it is among the few where the RDS module can typically be loaded by default. How it works tl;dr The...
