CVE-2026-45955

A flaw was found in the Linux kernel's md/md-llbitmap component. This vulnerability occurs when a suspend operation times out, failing to properly reset a critical internal reference. This oversight leaves the system's page control structure in an unusable state. This issue can lead to system...

CVE-2026-46073

A flaw was found in the Linux kernel's hwmon subsystem, specifically within the powerz driver. When a signal interrupt occurs during the waitforcompletioninterruptibletimeout function, the system fails to properly abort the USB Request Block URB. This oversight can lead to the kernel attempting t...

CVE-2026-46102

A flaw was found in the Linux kernel's network stream parser. This vulnerability occurs when the stream parser is unexpectedly stopped, such as during a message assembly timeout. A partially processed network message is not properly released from memory, leading to a memory leak. An attacker coul...
