kernel: usb: usbfs: fix use-after-free of usb_device in usbdev_release()

A flaw was found in the Linux kernel's USB subsystem usbfs. An unprivileged local attacker with read/write access to a /dev/bus/usb node could exploit a use-after-free vulnerability. This occurs because the usbdevice structure is prematurely freed before all pending operations are completed...

kernel: netfilter: flowtable: hold reference on ct until flow is released

A flaw was found in the Linux kernel's netfilter subsystem. In the flowtable component, connection tracking reference counts are prematurely released before flow entries are fully removed from memory. An attacker could exploit this timing issue during network flow processing, triggering a...

kernel: fuse: re-lock request before replacing page cache folio

A flaw was found in the Linux kernel's Filesystem in Userspace FUSE component. The fusetrymovefolio function, responsible for managing page cache folios, fails to re-lock a request after initially unlocking it on a successful path. This oversight allows another function, fusechanabort, to...

kernel: net/handshake: Take a long-lived file reference at submit

A flaw was found in the Linux kernel's networking handshake component. This vulnerability occurs because a critical file reference is not properly maintained during the handshake process. An attacker could potentially exploit this by causing the system to prematurely release a socket, leading to ...

kernel: ipvs: reload ip header after head reallocation

A flaw was found in the Linux kernel's IP Virtual Server IPVS module. When processing network packets, a buffer reallocation can leave an IP header pointer referencing freed memory. An attacker could exploit this use-after-free condition to cause a Denial of Service DoS by crashing the system or...

kernel: fuse: re-lock request before returning from fuse_ref_folio()

A flaw was found in the Linux kernel's FUSE Filesystem in Userspace component. The fusereffolio function does not properly re-lock a request after unlocking it, which can lead to a use-after-free vulnerability. A local attacker could exploit this flaw to potentially execute arbitrary code or caus...

kernel: vfio/pci: clear vdev->msi_perm after freeing it on init failure

A flaw was found in the Linux kernel's vfio/pci component. During device initialization, a memory pointer is not properly cleared after being freed, leading to a use-after-free and double-free vulnerability. A local attacker could exploit this flaw to cause a system crash, resulting in a denial o...
