kernel: selinux: fix overlayfs mmap() and mprotect() access checks

A flaw was found in the Linux kernel's SELinux security module when handling overlayfs. The existing security model for overlayfs does not properly enforce access controls for mmap and mprotect operations. This oversight could allow a local attacker to bypass intended security policies, potential...

kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...

kernel: net: atm: fix crash due to unvalidated vcc pointer in sigd_send()

A flaw was found in the Linux kernel's Asynchronous Transfer Mode ATM networking component. A local attacker, by acting as a malicious signaling daemon, could send a specially crafted message containing an unvalidated pointer. This unvalidated pointer would be directly used by the kernel, leading...

kernel: HID: wacom: fix out-of-bounds read in wacom_intuos_bt_irq

A flaw was found in the Linux kernel's Wacom Human Interface Device HID driver. This vulnerability allows a remote attacker to trigger an out-of-bounds read by sending a specially crafted, short Bluetooth HID report. This can lead to the disclosure of sensitive information from the system's memor...

kernel: scsi: target: iscsi: Fix CRC overread and double-free in iscsit_handle_text_cmd()

A flaw was found in the Linux kernel's iSCSI Internet Small Computer System Interface target subsystem. This vulnerability involves a buffer overread and a double-free error when processing iSCSI Text commands. A remote attacker could exploit these issues by sending specially crafted network...

An update for kernel is now available for Red Hat Enterprise Linux 8.6 Advanced Mission Critical Update Support and Red Hat Enterprise Linux 8.6 Extended Update Support Long-Life Add-On. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerabilit...

CVE-2026-64565

A flaw was found in the Linux kernel's ims-pcu component. A malicious USB device can send an oversized data packet, which is not properly handled. This can lead to a heap buffer overflow, allowing an attacker to manipulate internal pointers. Successful exploitation could result in a control flow...

CVE-2026-64563

A flaw was found in the Linux kernel. This vulnerability, known as a use-after-free, occurs in the rhashtable component when the system improperly handles hash table restarts. An attacker could potentially exploit this by causing the system to access memory that has already been released, which m...

CVE-2026-64562

A flaw was found in the Linux kernel's Kernel-based Virtual Machine KVM nested virtualization nVMX feature. This vulnerability occurs because the shadow Virtual Machine Control Structure VMCS is freed prematurely while still being referenced. Due to asynchronous operations, a virtual CPU vCPU mig...

Security update for the Linux Kernel

The SUSE Linux Enterprise 15 SP7 kernel was updated to fix various security issues: The following security issues were fixed: CVE-2025-68741: scsi: qla2xxx: Fix improper freeing of purex item bsc1255703. CVE-2025-68818: scsi: Revert "scsi: qla2xxx: Perform lockless command completion in abort pat...

SUSE-SU-2026:3790-1 Security update for the Linux Kernel

CVE-2026-74728

A flaw was found in the Linux kernel's XFS filesystem. When the system attempts to allocate memory for an XFS buffer and that allocation fails, the xfsbuffree function is called with a null buffer address. This leads to a null pointer dereference, causing the kernel to crash. This vulnerability c...

CVE-2026-74678

A flaw was found in the Linux kernel's ax88179178a USB network driver. When the network interface has scatter-gather SG enabled and a packet linearization operation fails, the system fails to free the associated memory buffer. This oversight leads to a memory leak, which could be exploited by an...

CVE-2026-74676

A flaw was found in the Linux kernel. A missing permission check in the KDSKBMETA ioctl input/output control allows a local process to modify the keyboard meta mode on a non-controlling console without proper authorization. This could enable an attacker to make unauthorized changes to system...

CVE-2026-74653

A flaw was found in the Linux kernel's 8250of serial driver, specifically affecting NXP LPC32xx UARTs. A local user could repeatedly open a specific serial port, triggering a stuck RX character-timeout interrupt. This leads to an interrupt storm that can livelock the CPU, resulting in a Denial of...

CVE-2026-74633

A flaw was found in the Linux kernel's tracing module. A local user can trigger a NULL pointer dereference by attempting to remove a specific event filter for an unloaded module. This vulnerability arises when a module-only event filter is cached with a null match, and a subsequent write operatio...

CVE-2026-74622

A flaw was found in the Linux kernel's 'atlantic' network driver. The aqringrxdeinit function, responsible for deinitializing receive RX buffers, fails to properly free pages and their associated Direct Memory Access DMA mappings for buffers that have been consumed but not yet refilled. This...

CVE-2026-74708

A flaw was found in the Linux kernel's xsk AFXDP socket component. This vulnerability arises from improper validation of launch-time metadata size, where the metadata can extend beyond its allocated structure. This could lead to inconsistent decisions if user space concurrently changes flags,...
