CVE-2025-68250

In the Linux kernel, the following vulnerability has been resolved: hungtask: fix warnings caused by unaligned lock pointers The blocker tracking mechanism assumes that lock pointers are at least 4-byte aligned to use their lower bits for type encoding. However, as reported by Eero Tamminen, some...

USN-7938-1 linux-azure-5.15 vulnerabilities

Jean-Claude Graf, Sandro Rüegge, Ali Hajiabadi, and Kaveh Razavi discovered that the Linux kernel contained insufficient branch predictor isolation between a guest and a userspace hypervisor for certain processors. This flaw is known as VMSCAPE. An attacker in a guest VM could possibly use this t...

CVE-2025-68257

CVE-2025-68257 : Linux kernel COMEDI subsystem vulnerability where compat ioctl handlers could dereference a NULL callback when the device was not attached. Root cause: compat ioctls lacked a proper sanity check of device attached status, allowing a NULL dereference in path leading to a crash. Fi...

CVE-2025-68250

CVE-2025-68250 affects the Linux kernel. The issue arises from an assumption that lock pointers are 4-byte aligned to use lower bits for type encoding, which fails on architectures with only 2-byte alignment (e.g., m68k). This causes two WARN_ON_ONCE checks to trigger in the hung_task blocker log...

CVE-2025-68192

In the Linux kernel, the following vulnerability has been resolved: net: usb: qmiwwan: initialize MAC header offset in qmimuxrxfixup Raw IP packets have no MAC header, leaving skb-macheader uninitialized.
