UBUNTU-CVE-2026-47335

Ubuntu Linux 6.8 contains SAUCE patches with a possible NULL pointer dereference in the handling of AppArmor notifications. The bug can be triggered by an unprivileged local user. This can lead to a kernel panic...

UBUNTU-CVE-2026-47337

Ubuntu Linux 6.8, 6.17 and 7.0 contain SAUCE patches with a possible NULL pointer dereference in the handling of AFINET/AFINET6 socket mediation. The bug can be triggered by an unprivileged local user. This can lead to a kernel oops...

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-2026-45966

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-2026-45965

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-2026-45978

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...

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-2026-46020

A flaw was found in the Linux kernel's DAMON Data Access MONitor core. A privileged local user can exploit this vulnerability by providing an invalid node ID to damosquotagoal-nid for nodememused,freebp via the DAMON user-space tool. This improper validation can lead to an out-of-bounds memory...

CVE-2026-46024

A flaw was found in the Linux kernel's libceph component. A remote attacker could send a specially crafted authentication reply message to trigger a null pointer dereference. This vulnerability can lead to a system crash, resulting in a Denial of Service DoS for affected systems. Mitigation To...

CVE-2026-44710

pam_usb for Linux is affected by a NULL pointer dereference in src/device.c prior to 0.8.7, where return values from udisks_drive_get_serial(), udisks_drive_get_vendor(), and udisks_drive_get_model() were passed directly to strcmp() without NULL checks. The GIO/UDisks API can return NULL for thes...

CVE-2026-44710 pam_usb: NULL pointer dereference from UDisks device fields causes PAM crash and login denial-of-service

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...

CVE-2026-8360

Function calls to WOSCommonUtil.dll!WOSSysInfoGetDeviceInterface in various DLLs i.e., WOSProfileMgrModule.dll, WOSWebDavModule.dll can return a NULL pointer i.e., when no user is logged into the Triofox Server Agent Management Console. The returned NULL pointer is not checked before being...

CVE-2026-8359

When processing a request with a URL path starting with /status or /sysinfo, WOSHttpStatusModule.dll is to be loaded to handle such URL patterns. The WOSBinLoadHttpModule function in the dll would be called to set up a "module" object for that module. However, WOSHttpStatusModule.dll is not prese...
