Linux Kernel Security Vulnerabilities

The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from an out-of-bounds read in the symlinkdata function within smb/client. This vulnerability arises because...

CVE-2026-46001

A flaw was found in the Linux kernel's hwmon pt5161l driver. The pt5161lreadblockdata function is vulnerable to a buffer overrun, where it can receive more data than its allocated buffer size. This can lead to memory corruption. Additionally, the function may return an unexpected positive value o...

Protection Mechanism Failure

Overview Affected versions of this package are vulnerable to Protection Mechanism Failure via the NewParsedRequestFromRequest function. An attacker can bypass body-inspection mechanisms and evade detection by manipulating HTTP request headers to omit or alter the Content-Length value, causing the...

CrowdSec AppSec silently drops request body for chunked / HTTP-2 requests

Summary The CrowdSec AppSec component fails to read the HTTP request body for any request whose Content-Length is not positive — most notably HTTP/1.1 requests using Transfer-Encoding: chunked and HTTP/2 requests sent without a content-length header. Coraza is then evaluated against an empty body...

CVE-2026-46039

A flaw was found in the Linux kernel. A potential integer overflow in the rxgkextracttoken function, specifically during the length check of a ticket, could occur. This issue arises from rounding up the value to be tested, which might lead to an overflow. This could potentially result in...

JLSEC-2026-566 In GnuPG before 2.5.17, a long signature packet length causes `parse_signature` to return success...

In GnuPG before 2.5.17, a long signature packet length causes parsesignature to return success with sig-data set to a NULL value, leading to a denial of service application crash...

CVE-2026-44378

Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which...

CVE-2026-46085

A flaw was found in the Linux kernel's rxrpc subsystem, specifically in the rxkad crypto unalignment handling. A remote attacker could send a specially crafted packet with a misaligned crypto length. This improper handling could lead to system instability or a denial of service DoS due to incorre...

CVE-2026-46088

A flaw was found in the Linux kernel's Advanced Linux Sound Architecture ALSA control component. Improper validation of the buffer length before a string length operation in the sndctleleminitenumnames function can lead to a system panic. This vulnerability could allow a local attacker to trigger...

CVE-2026-44378 Botan: Quadratic complexity decoding BER indefinite length encodings

Botan is a C++ cryptography library. Prior to 3.12.0, certain patterns of indefinite length encodings in BER data could cause quadratic behavior in the parser, resulting in a denial of service. Such BER encodings were accepted even in structures which are required to be encoded as DER, which...

CVE-2026-44378

Botan (C++ cryptography library) is affected prior to version 3.12.0. Indefinite-length BER encodings could trigger quadratic parser behavior, even in structures that must be DER, leading to denial of service. The issue is fixed in 3.12.0. There are no explicit exploit details or in-the-wild expl...

DEBIAN-CVE-2026-47104

libusb before version 1.0.30 contains a one-byte out-of-bounds read vulnerability in parseiadarray in descriptor.c that allows attackers to trigger a denial of service by supplying a malformed USB descriptor whose bLength equals size minus one, causing the bounds check to use the original buffer...

CVE-2026-46088

In the Linux kernel, the following vulnerability has been resolved: ALSA: control: Validate buflen before strnlen in sndctleleminitenumnames sndctleleminitenumnames advances pointer p through the names buffer while decrementing buflen. If buflen reaches zero but items remain, the next iteration...

CVE-2026-46085

In the Linux kernel, the following vulnerability has been resolved: rxrpc: Fix rxkad crypto unalignment handling Fix handling of a packet with a misaligned crypto length. Also handle non-ENOMEM errors from decryption by aborting. Further, remove the WARNONONCE so that it can't be remotely trigger...
