CVE-2026-45959

The CVE-2026-45959 issue affects the Linux kernel crypto: CCP driver. A local pointer annotated with __cleanup(kfree) could cause kfree to receive the local stack address instead of the allocated memory, leading to a crash. The underlying cause is incorrect cleanup usage; the repository indicates...

CVE-2026-45958

The CVE-2026-45958 vulnerability affects the Linux kernel, specifically the drm/exynos vidi driver. In vidi_connection_ioctl(), the code dereferenced a user pointer directly (vidi->edid(user pointer)), enabling arbitrary kernel memory access from user space and potentially leading to privilege...

CVE-2026-45958

In the Linux kernel, the following vulnerability has been resolved: drm/exynos: vidi: fix to avoid directly dereferencing user pointer In vidiconnectionioctl, vidi-ediduser pointer is directly dereferenced in the kernel. This allows arbitrary kernel memory access from the user space, so instead o...
