CVE-2026-63957

A flaw was found in the Linux kernel. A malicious Universal Serial Bus USB device can exploit a vulnerability in the safeserial driver by reporting a bulk-out buffer size smaller than eight bytes. This can lead to user-controlled slab corruption, a form of memory corruption, when the driver...

CVE-2026-63956

A flaw was found in the Linux kernel's cypressm8 USB serial driver. A malicious Universal Serial Bus USB device could report a packet size smaller than eight bytes for the interrupt-out endpoint. This can lead to memory corruption, specifically user-controlled slab corruption or a NULL-pointer...

CVE-2026-63903

A flaw was found in the Linux kernel's belkinsa USB serial driver. The driver's interrupt handling routine fails to validate the length of incoming status reports. This oversight allows a local attacker, by connecting a specially crafted USB device, to trigger an out-of-bounds read. The primary...

CVE-2026-63898

A flaw was found in the Linux kernel's mctu232 USB serial driver. A malicious USB device could exploit this vulnerability by reporting a smaller endpoint maximum packet size than the driver expects. This incorrect handling of transfer sizes can lead to memory corruption, potentially allowing an...

CVE-2026-63901

A flaw was found in the Linux kernel's digiacceleport USB serial driver. A malicious Universal Serial Bus USB device could report smaller bulk-out buffers than expected. This lack of proper size validation could lead to out-of-bounds memory accesses or slab corruption, potentially causing system...

CVE-2026-63964

A flaw was found in the Linux kernel's USB Type-C UCSI CCG driver. A local attacker with root privileges can provide a specially crafted firmware image without a required record header. This malformed image can cause a null pointer dereference within the doflash function, leading to a kernel cras...

CVE-2026-63905

A flaw was found in the Linux kernel's USB/IP Virtual USB Device Controller vudc component. A race condition exists in the vudcremove function, which can lead to a use-after-free vulnerability. This occurs when the system attempts to free a data structure while a timer within it is still active o...

CVE-2026-63904

A flaw was found in the Linux kernel's USB Test and Measurement Class USBTMC driver. This vulnerability occurs because the driver does not properly verify the size of incoming notification messages, specifically failing to ensure that required two-byte headers are present. An attacker could explo...

CVE-2026-63896

A flaw was found in the Linux kernel's USB gadget composite driver. A remote attacker, acting as a malicious USB host, could send a specially crafted GETURL request. This request, with a small wLength value, triggers an integer underflow when calculating the buffer length for a memory copy...

CVE-2026-63928

A flaw was found in the Linux kernel's USB serial omninet driver. A malicious Universal Serial Bus USB device could exploit this by reporting a smaller maximum packet size than anticipated. This action would cause the system to allocate undersized data buffers, leading to memory corruption. Such...

Linux Distros Unpatched Vulnerability : CVE-2026-63904

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - usb: usbtmc: check URB actuallength for interrupt-IN notifications USBTMC devices can use an optional interrupt endpoint for notification messages. These...

SUSE CVE-2026-63821

In the Linux kernel, the following vulnerability has been resolved: wifi: rtw88: usb: fix memory leaks on USB write failures When rtwusbwriteport fails to submit a USB Request Block URB e.g., due to device disconnect or ENOMEM, the completion callback is never executed. Currently, the driver...

CVE-2026-63957

In the Linux kernel, the following vulnerability has been resolved: USB: serial: safeserial: fix memory corruption with small endpoint Make sure that the bulk-out buffer size is at least eight bytes to avoid user-controlled slab corruption in "safe" mode should a malicious device report a smaller...

CVE-2026-63928

In the Linux kernel, the following vulnerability has been resolved: USB: serial: omninet: fix memory corruption with small endpoint Make sure that the bulk-out buffers are at least as large as the hardcoded transfer size to avoid user-controlled slab corruption should a malicious device report a...

CVE-2026-63906

In the Linux kernel, the following vulnerability has been resolved: usb: musb: omap2430: Fix use-after-free in omap2430probe In omap2430probe, ofnodeputnp is called prematurely before the last access to np, leading to a use-after-free if the node's reference count drops to zero. Move the ofnodepu...

CVE-2026-63903

In the Linux kernel, the following vulnerability has been resolved: USB: serial: belkinsa: validate interrupt status length The Belkin interrupt callback treats interrupt data as a four-byte status report and reads LSR/MSR fields at offsets 2 and 3. The interrupt-in buffer length is derived from...

CVE-2026-63901

In the Linux kernel, the following vulnerability has been resolved: USB: serial: digiacceleport: fix memory corruption with small endpoints Add the missing bulk-out buffer size sanity checks to avoid out-of-bounds memory accesses or slab corruption should a malicious device report smaller buffers...
