Vulnerability from github – Published: 2026-04-24 15:32 – Updated: 2026-06-01 18:31In the Linux kernel, the following vulnerability has been resolved:
usb: gadget: f_phonet: fix skb frags[] overflow in pn_rx_complete()
A broken/bored/mean USB host can overflow the skb_shared_info->frags[] array on a Linux gadget exposing a Phonet function by sending an unbounded sequence of full-page OUT transfers.
pn_rx_complete() finalizes the skb only when req->actual < req->length, where req->length is set to PAGE_SIZE by the gadget. If the host always sends exactly PAGE_SIZE bytes per transfer, fp->rx.skb will never be reset and each completion will add another fragment via skb_add_rx_frag(). Once nr_frags exceeds MAX_SKB_FRAGS (default 17), subsequent frag stores overwrite memory adjacent to the shinfo on the heap.
Drop the skb and account a length error when the frag limit is reached, matching the fix applied in t7xx by commit f0813bcd2d9d ("net: wwan: t7xx: fix potential skb->frags overflow in RX path").

Vulnerability from github – Published: 2026-03-09 18:31 – Updated: 2026-06-26 21:32In the Linux kernel, the following vulnerability has been resolved:
fs/xattr: missing fdput() in fremovexattr error path
In the Linux kernel, the fremovexattr() syscall calls fdget() to acquire a file reference but returns early without calling fdput() when strncpy_from_user() fails on the name argument. In multi-threaded processes where fdget() takes the slow path, this permanently leaks one file reference per call, pinning the struct file and associated kernel objects in memory. An unprivileged local user can exploit this to cause kernel memory exhaustion. The issue was inadvertently fixed by commit a71874379ec8 ("xattr: switch to CLASS(fd)").

Vulnerability from github – Published: 2022-05-24 19:04 – Updated: 2022-08-06 00:00Multiple vulnerabilities in the implementation of the Cisco Discovery Protocol and Link Layer Discovery Protocol (LLDP) for Cisco Video Surveillance 7000 Series IP Cameras could allow an unauthenticated, adjacent attacker to cause a memory leak, which could lead to a denial of service (DoS) condition on an affected device. These vulnerabilities are due to incorrect processing of certain Cisco Discovery Protocol and LLDP packets at ingress time. An attacker could exploit these vulnerabilities by sending crafted Cisco Discovery Protocol or LLDP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, which could cause the device to crash and reload, resulting in a DoS condition. Note: Cisco Discovery Protocol and LLDP are Layer 2 protocols. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).

Vulnerability from github – Published: 2022-05-24 17:17 – Updated: 2022-05-24 17:17A vulnerability in the VPN System Logging functionality for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a memory leak that can deplete system memory over time, which can cause unexpected system behaviors or device crashes. The vulnerability is due to the system memory not being properly freed for a VPN System Logging event generated when a VPN session is created or deleted. An attacker could exploit this vulnerability by repeatedly creating or deleting a VPN tunnel connection, which could leak a small amount of system memory for each logging event. A successful exploit could allow the attacker to cause system memory depletion, which can lead to a systemwide denial of service (DoS) condition. The attacker does not have any control of whether VPN System Logging is configured or not on the device, but it is enabled by default.

Vulnerability from github – Published: 2022-11-01 19:00 – Updated: 2025-05-06 15:30Xenstore: guests can let run xenstored out of memory T[his CNA information record relates to multiple CVEs; the text explains which aspects/vulnerabilities correspond to which CVE.] Malicious guests can cause xenstored to allocate vast amounts of memory, eventually resulting in a Denial of Service (DoS) of xenstored. There are multiple ways how guests can cause large memory allocations in xenstored: - - by issuing new requests to xenstored without reading the responses, causing the responses to be buffered in memory - - by causing large number of watch events to be generated via setting up multiple xenstore watches and then e.g. deleting many xenstore nodes below the watched path - - by creating as many nodes as allowed with the maximum allowed size and path length in as many transactions as possible - - by accessing many nodes inside a transaction

GHSA-HFQR-838F-PJ36
Vulnerability from github – Published: 2025-10-01 12:30 – Updated: 2026-01-16 21:30In the Linux kernel, the following vulnerability has been resolved:
fs/ntfs3: Fix memory leak on ntfs_fill_super() error path
syzbot reported kmemleak as below:

Mitigation MIT-41
Strategy: Libraries or Frameworks
- Choose a language or tool that provides automatic memory management, or makes manual memory management less error-prone.
- For example, glibc in Linux provides protection against free of invalid pointers.
- When using Xcode to target OS X or iOS, enable automatic reference counting (ARC) [REF-391].
- To help correctly and consistently manage memory when programming in C++, consider using a smart pointer class such as std::auto_ptr (defined by ISO/IEC ISO/IEC 14882:2003), std::shared_ptr and std::unique_ptr (specified by an upcoming revision of the C++ standard, informally referred to as C++ 1x), or equivalent solutions such as Boost.
Mitigation
Use an abstraction library to abstract away risky APIs. Not a complete solution.
Mitigation
Consider using the Boehm-Demers-Weiser garbage collector (bdwgc), which can help avoid leaks.
