CVE-2026-74737

A flaw was found in the Linux kernel's am65-cpsw-nuss Ethernet driver. When processing incoming network packets, the driver incorrectly extracts the MAC Port ID from the Source Tag, using 16 bits instead of the intended lower 8 bits. This error can lead to the driver accessing out-of-bound memory...

CVE-2026-13586

A flaw was found in Bouncy Castle for Java. This vulnerability allows a remote attacker to cause a Denial of Service DoS by exploiting an iteration-count bound issue in the PKCS12 Message Authentication Code MAC and bag-decryption Key Derivation Function KDF. This could make the affected system...

CVE-2026-58060

A flaw was found in Bouncy Castle for Java. A remote attacker could exploit a vulnerability where the HSS public-key level count is unbounded. This allows for a huge memory allocation during the verification process, leading to a denial of service DoS condition. This issue affects Bouncy Castle f...

CVE-2026-13506

A flaw was found in Bouncy Castle for Java. A remote attacker could exploit a vulnerability related to how the software processes lazy ASN.1 sequences, which can reset an internal nesting-depth guard. This issue could lead to a Denial of Service DoS, making the affected system or application...

CVE-2026-12185

A flaw was found in Bouncy Castle for Java. The BKS/UBER keystore component allocates memory based on untrusted length values before performing an integrity check. A remote attacker could exploit this vulnerability by providing a specially crafted keystore, leading to excessive memory allocation...

CVE-2026-80584

A flaw was found in the Linux kernel's s390/qeth component. This vulnerability allows a local attacker to trigger an integer underflow when handling user-supplied buffer lengths in the qethsnmpcommand and qethl3arpquery functions. This can lead to an out-of-bounds write, potentially causing memor...

CVE-2026-74740

A flaw was found in the Linux kernel's network scheduler net/sched: actapi. A Time-of-Check to Time-of-Use TOCTOU race condition exists where a pointer can be cleared between two reads. This allows a concurrent operation to cause a NULL dereference, potentially leading to a system crash and Denia...

CVE-2026-80572

A flaw was found in the Linux kernel's byd input driver. A race condition exists during device disconnection where the byddisconnect function frees private data before ensuring that a timer callback, bydcleartouch, has completed. This can lead to the callback attempting to access memory after it...

Security Bulletin: Security vulnerability is addressed in IBM Daeja ViewONE as part of iFix release in August 2026

Summary Vulnerability reported in a third party library used by IBM Daeja ViewONE to handle certain PDF documents – specifically those that are encrypted or digitally signed. Vulnerability Details CVEID:CVE-2026-59645 DESCRIPTION: In Bouncy Castle for Java before 1.85, OER parser recurses without...

CVE-2026-80582

A flaw was found in the Linux kernel's drm/shmemhelper component. This vulnerability arises from insufficient boundary checks when handling large memory pages. An attacker could potentially trigger an attempt to map memory outside its designated area. This improper memory handling could lead to a...

CVE-2026-80569

A flaw was found in the synaptics-rmi4 driver within the Linux kernel. A malicious or malfunctioning RMI4 device can exploit this vulnerability by reporting incorrect electrode counts. This leads to the driver attempting to write data beyond the allocated memory buffer, causing memory corruption...

CVE-2026-80565

A flaw was found in the Linux kernel's crypto: qce component. An error in the devmqceregisteralgs function's error handling path causes the system to repeatedly attempt to unregister algorithms incorrectly when a registration fails. This improper handling of resources could lead to system...

CVE-2026-81575

If configured as a server, CodeMeter Runtime before versions 8.41a and 9.10 accepts requests with opcode 0x5e, which contain the data length and the data itself. Missing bounds checking on the data length value can lead to out of bounds reads, causing a segmentation fault that ultimately crashes...

CVE-2026-81581

Improper validation of memory boundaries in WibuKey64.sys of WibuKey up to 6.70 for Windows can be exploited by an attacker by setting the pointers outside the scope of the program. This usually results in a denial of service, yet we cannot rule out the possibility of exploits that can cause Remo...

CVE-2026-80550

A flaw was found in the s390/vfioccw component of the Linux kernel. The ccwchaincalclength routine, which counts channel command words CCWs, incorrectly checked array boundaries. This could lead to an out-of-bounds read, where the system attempts to access memory beyond its allocated limits. Such...

CVE-2026-80489

A flaw was found in glibc. A remote attacker could exploit this vulnerability by providing specially crafted input during SHIFTJISX0213 to UCS-4 text conversion. This crafted input can cause the application to repeatedly process a buffered character without consuming further input, leading to a...

CVE-2026-80525

A flaw was found in the Linux kernel's Sound Open Firmware SOF IPC4 topology component. During suspend and resume operations, the system fails to refresh the Inter-Process Communication IPC payload for audio copier widgets. This oversight causes outdated Direct Memory Access DMA channel assignmen...

CVE-2026-80577

A flaw was found in the Linux kernel's drm/panthor driver. When the panthorfwloadsectionentry function processes zero-sized firmware sections, it can leave a memory pointer uninitialized. Subsequent operations that attempt to access this uninitialized memory can lead to a null pointer dereference...

CVE-2026-80580

A flaw was found in the fbdev component of the Linux kernel. This vulnerability arises because the modestring function, when generating output for the sysfs interface, can write more data than its allocated buffer can hold. An attacker could exploit this by providing a specially crafted input,...
