In the Linux kernel, the following vulnerability has been resolved: nvmet-tcp: check INITFAILED before nvmetrequninit in digest error path In nvmettcptryrecvddgst, when a data digest mismatch is detected, nvmetrequninit is called unconditionally. However, if the command arrived via the...

CVE-2026-64418

A flaw was found in the Linux kernel's memory management mm shrinker subsystem. A race condition exists where the shrinkerinfo array can be prematurely freed while still accessible, leading to a use-after-free or double-free vulnerability. This memory corruption can be exploited by a local attack...

CVE-2026-64290

A flaw was found in the Linux kernel's iommufd component. When a copytouser operation fails within the iommufdfaultfopsread function, the system enters an infinite loop. This continuous retry consumes 100% of the CPU and holds a mutex, which can lead to a denial of service DoS for affected system...

CVE-2026-64342

A flaw was found in the Linux kernel's USB iowarrior driver. This vulnerability, a use-after-free, occurs because write operations are not properly halted when a device disconnects. An attacker could potentially exploit this to cause system instability or execute arbitrary code...

CVE-2026-64384

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability occurs due to a double-free error when handling change notify replies. If a response attempt returns a replayable error and frees its buffer, and then SMB2notifyinit fails, the same buffer can be freed agai...

CVE-2026-64314

A flaw was found in the Linux kernel's chacha20poly1305 cryptographic module. This vulnerability occurs because the chachapolycreate function does not properly validate a poly1305 template argument. When this argument is missing, an error pointer is incorrectly passed to a string comparison...

CVE-2026-64424

A flaw was found in the Linux kernel's netpoll module. During the system shutdown process, a race condition can occur where a network transmission worker attempts to access memory that has already been deallocated. This use-after-free vulnerability can lead to system instability, causing a denial...

CVE-2026-64431

A flaw was found in the Linux kernel's NTFS file system driver. A remote attacker could exploit this vulnerability by providing a specially crafted NTFS image, leading to out-of-bounds memory access. This memory corruption can cause the system to crash, resulting in a denial of service...

CVE-2026-64433

A flaw was found in the Linux kernel's Bluetooth Management MGMT subsystem. A use-after-free UAF vulnerability exists in the adddevicecomplete function. This occurs because the function does not properly acquire a lock before accessing connection parameters, allowing a concurrent device removal...

Security update for the Linux Kernel (Live Patch 14 for SUSE Linux Enterprise 15 SP7)

This update for the SUSE Linux Enterprise Kernel 6.4.0-150700.53.52 fixes various security issues: The following security issues were fixed: CVE-2026-23240: tls: Fix race condition in tlsswcancelworktx bsc1262404. CVE-2026-31738: vxlan: validate ND option lengths in vxlannacreate bsc1264060...

CVE-2026-64349

A flaw was found in the Linux kernel's USB dwc3 driver. Incorrect type handling in the dwc3readl and dwc3writel functions within dwc3ulpisetup can lead to memory corruption. This vulnerability may allow an attacker to cause system instability or potentially execute arbitrary code, depending on th...

CVE-2026-64277

A flaw was found in the Linux kernel's synaptics-rmi4 input driver. The rmif3amapgpios function incorrectly allocates memory for the gpiokeymap, making it smaller than required. This allows a device reporting a specific gpiocount value to trigger an out-of-bounds read, leading to information...

CVE-2026-64325

A flaw was found in the Linux kernel's mt76 Wi-Fi driver, affecting mt7921 and mt7925 chipsets. When a channel-switch announcement CSA beacon is received, a timing issue can occur if a station disconnects before a queued work item processes the beacon. This can lead to a NULL pointer dereference ...

CVE-2026-64346

A flaw was found in the Linux kernel's USB gadget driver. A race condition exists where the udc USB Device Controller memory, which manages USB gadgets, can be freed while still being accessed. This use-after-free vulnerability can be triggered by a local attacker, potentially through operations...

CVE-2026-64437

A flaw was found in the ksmbd component of the Linux kernel. This vulnerability allows an authenticated client using the Server Message Block SMB protocol to trigger a use-after-free error. By sending specific close and cancel requests, an attacker can cause the kernel to crash, leading to a deni...

CVE-2026-64377

A flaw was found in the Linux kernel's qcom-cpufreq-hw driver. This vulnerability, a double free, occurs due to incorrect memory handling when a device is detached. Specifically, the system attempts to release memory that is already managed, leading to a potential double free. This can result in...

CVE-2026-64515

A flaw was found in the Linux kernel's mac80211 Wi-Fi subsystem. This vulnerability arises from incorrect handling of Multi-Link Element MLE defragmentation. When a reconf or EPCS Enhanced Power Save MLE is present in a non-transmitted profile, the defragmentation routine uses an incorrect pointe...
