The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from the stmmac driver, where a null pointer derefrence exception may occur when RX memory is exhausted...

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...

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...
