The vulnerability of the WINS-server software Samba, which allows a hacker to trigger a service failure

The vulnerability of the WINS-server software Samba is related to pointer aliasing. Exploiting this vulnerability can allow a malicious actor to cause service failures remotely...

CVE-2026-45958

A flaw was found in the Linux kernel's drm/exynos: vidi driver. A local user could exploit this vulnerability by directly dereferencing a user pointer in the vidiconnectionioctl function. This allows for arbitrary kernel memory access from user space, potentially leading to privilege escalation o...

CVE-2026-45965

A flaw was found in the AppArmor security module of the Linux kernel. When the exportbinary parameter is disabled at runtime, a previously loaded profile that is subsequently replaced can lead to a NULL pointer dereference. This occurs when the system attempts to resolve symbolic links to raw dat...

CVE-2026-45966

A flaw was found in the AppArmor security module within the Linux kernel. This vulnerability occurs when the system processes file descriptors, which are references to open files or other I/O resources, using a specific inter-process communication mechanism called SCMRIGHTS. A missing check for...

CVE-2026-45978

A flaw was found in the Linux kernel's Greybus Lights subsystem. This vulnerability occurs when the gblightslightconfig function attempts to store a channel count before successfully allocating the corresponding channels array. If the memory allocation fails, a subsequent cleanup operation can tr...

CVE-2026-45982

A flaw was found in the Linux kernel. A NULL pointer dereference in the acpievaddressspacedispatch function could allow a local attacker to cause a denial of service DoS by triggering a missed execution path. This vulnerability arises from an incomplete check in the Advanced Configuration and Pow...

httpd: mod_authn_socache: NULL pointer dereference can cause a child process crash

A flaw was found in the modauthnsocache module of httpd. This vulnerability allows an unauthenticated remote user to crash a child process due to a NULL pointer dereference when the server is operating in a caching forward proxy configuration...

CVE-2026-44710

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.8.7, src/device.c passed the return values of udisksdrivegetserial, udisksdrivegetvendor, and udisksdrivegetmodel directly to strcmp without NULL checks. The GIO/UDisks API documentation states these...
