CVE-2026-64188

In the Linux kernel RMNET net path, CVE-2026-64188 stems from use-after-free: rmnet_dellink() frees a rmnet_endpoint with kfree() while RCU readers may still reference ep->egress_dev, risking a fault in the receive path. The fix adds an rcu_head to struct rmnet_endpoint and replaces kfree() wi...

CVE-2026-53399

A flaw was found in the Linux kernel's Network File System Daemon nfsd. When a setlease operation fails, the system prematurely releases a layout state identifier. An attacker could exploit this by triggering the failure, leading to a use-after-free vulnerability. This could result in a system...

CVE-2026-53388

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...

CVE-2026-53384

A flaw was found in the Linux kernel's 8250dw serial driver. When the clknotifierregister function fails during the probe process, the 8250 port is not properly unregistered. This oversight can lead to a use-after-free vulnerability, where previously freed memory is still referenced. An attacker...

CVE-2026-53381

A flaw was found in the virtiofs component of the Linux kernel. A use-after-free UAF vulnerability exists during submount unmount operations. This occurs because the iput function, called from fusereleaseend, can attempt to access a super block that has already been destroyed. This can lead to a...

CVE-2026-64037

A flaw was found in the Linux kernel's iwlwifi MLD driver. When the Aggregated MAC Service Data Unit AMSDU feature is disabled, the driver incorrectly processes Transmit Segmentation Offload TSO requests. This can lead to a flood of micro-frames on the transmit ring, resulting in memory corruptio...

CVE-2026-64178

A flaw was found in the Linux kernel's Bluetooth Network Encapsulation Protocol BNEP module. A local attacker with administrative network capabilities CAPNETADMIN could exploit a use-after-free vulnerability in the bnepaddconnection function. This occurs because the function fails to properly...

CVE-2026-64122

A flaw was found in the Linux kernel's mlx5e network driver. The mlx5etxreportertimeoutrecover function attempts to access network device resources after they have been deallocated, leading to a use-after-free vulnerability. This could allow a local attacker to cause a denial of service system...

The vulnerability of Microsoft Office packages and 365 Apps for Enterprise lies in the use of memory after it is freed, allowing an attacker to execute arbitrary code.

The vulnerability of Microsoft Office packages and 365 Apps for Enterprise lies in the use of memory after it is freed. Exploiting this vulnerability can allow an attacker to execute arbitrary code...

CVE-2026-64051

A flaw was found in the Linux kernel's accel/qaic driver. This vulnerability allows for memory to be mapped beyond its intended boundaries during certain memory allocation operations. A local attacker could exploit this flaw, leading to a use-after-free condition. This could potentially result in...

CVE-2026-64109

A flaw was found in the Linux kernel's afunix UNIX domain sockets component. A race condition in the unixstreamdatawait function allows a local attacker to trigger a Use-After-Free UAF vulnerability. This occurs because the function peeks at a socket buffer without proper locking, enabling anothe...

CVE-2026-64132

A flaw was found in the Linux kernel's IPv6 In-situ Operations, Administration, and Maintenance IOAM component. This vulnerability, a use-after-free, occurs when the kernel fails to correctly update a pointer after reallocating a network packet's buffer. This oversight could allow an attacker to...

CVE-2026-64123

A flaw was found in the Linux kernel's High-availability Seamless Redundancy HSR networking component. When HSR node-list and node-status operations are performed, a generic-netlink reader might retain a pointer to a freed node table. This can lead to a use-after-free vulnerability, potentially...

CVE-2026-64061

A flaw was found in the Linux kernel's network file system netfs. This use-after-free vulnerability occurs when the netfsreadgaps function prematurely releases a memory page during network read operations. A remote attacker could exploit this by sending specially crafted network traffic, leading ...

CVE-2026-64115

A flaw was found in the vsock/vmci component of the Linux kernel. A remote attacker could exploit a Use-After-Free UAF vulnerability when a peer resets a connection during the handshake process. This occurs because the system incorrectly handles reset packets, leading to a pending socket being le...

SUSE CVE-2026-53381

In the Linux kernel, the following vulnerability has been resolved: virtiofs: fix UAF on submount umount iput called from fusereleaseend can Oops if the super block has already been destroyed. Normally this is prevented by waiting for numwaiting to go down to zero before commencing with super blo...

SUSE CVE-2026-53384

In the Linux kernel, the following vulnerability has been resolved: serial: 8250dw: unregister 8250 port if clknotifierregister fails dw8250probe registers the 8250 port via serial8250register8250port and then, if the device has a clock, registers a clock notifier. If clknotifierregister fails,...

SUSE CVE-2026-53388

In the Linux kernel, the following vulnerability has been resolved: fuse: re-lock request before replacing page cache folio fusetrymovefolio unlocks the request on entry but does not re-lock it on the success path. This means fusechanabort can end the request and free the fuseioargs eg...
