CVE-2026-90034

CVE-2026-90034 affects the Linux kernel's usb_mdc800 driver (USB Image MDC800). The root cause is the use of kmalloc() instead of kzalloc() for the irq_urb_buffer and download_urb_buffer allocations in usb_mdc800_init(). Because the memory is not zero-initialized, a shorter-than-expected message ...

In the Linux kernel, the following vulnerabilities have been resolved: vhost/vsock: Use kvmalloc/kvfree for larger packets. When copying a large file via sftp using vsock, the data size is usually 32 kB. In such cases, kmalloc seems to fail when attempting to allocate 32 32 kB regions. vhost-5837...

Astra Linux – Vulnerabilities in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: media: coda: A check for kmalloc has been added. Since kmalloc may return a NULL pointer, it is better to check the return value to avoid dereferencing a NULL pointer, just like with the other cases...

Astra Linux – Vulnerability in Linux 5.15

A NULL pointer dereference flaw was discovered in the Linux kernel’s drivers/gpu/drm/msm/msmgemsubmit.c code, specifically in the submitlookupcmds function. This flaw occurs because there is no check on the return value of kmalloc. This issue allows a local user to crash the system...
