CVE-2026-89535

A flaw was found in the svcrdma module of the Linux kernel. A use-after-free vulnerability can occur due to an incorrect order of operations during the teardown of an RDMA Remote Direct Memory Access transport. If a device unregistration process happens concurrently, it can attempt to access a...

CVE-2026-80991

A flaw was found in the Linux kernel's net: ravb module. A race condition exists during the Precision Time Protocol PTP clock teardown. This allows the ravbptpinterrupt function to attempt to use a PTP clock after it has been freed by ptpclockunregister, leading to a use-after-free vulnerability...

CVE-2026-89488

A flaw was found in the Linux kernel's Open vSwitch OVS component. An unprivileged user, operating from a user and network namespace, can trigger a use-after-free vulnerability during network namespace teardown. This occurs because packet processing attempts to use connection tracking CT limit...

CVE-2026-89465

A flaw was found in the Linux kernel, specifically within the rt9455 power supply driver. This vulnerability occurs due to improper management of delayed tasks when the device is being removed or if its initialization fails. A pending task can attempt to access memory that has already been...

CVE-2026-89677

A flaw was found in the Linux kernel's Network File System Daemon nfsd. When creating files, the dentrycreate function could return an unexpected directory entry dentry. This could lead to a previously stored dentry being prematurely freed and then used again, potentially causing memory corruptio...

CVE-2026-89637

A flaw was found in the Linux kernel's Server Message Block SMB client. When processing a malformed secondary TRANSACT2 response, a use-after-free UAF vulnerability and a buffer leak can occur in the cifschecktrans2 function. This can lead to a dangling buffer being reused by the demux thread,...

CVE-2026-89478

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. An authenticated attacker could exploit a timing window during the removal of an SCTP transport. This could lead to the system attempting to read from freed memory, potentially causing a denial of...

CVE-2026-80928

A flaw was found in the Linux kernel's SMACK Simplified Mandatory Access Control Kernel security module. Incorrect handling of task credentials within the smackfilesendsigiotask function can lead to a Use-After-Free UAF vulnerability. A local attacker could exploit this flaw to potentially escala...

CVE-2026-89523

A flaw was found in the Linux kernel's MediaTek mt7925 Wi-Fi driver. When the device is reset, suspended, or unregistered, a pending work item mlopmwork can continue to execute. This can lead to the work item accessing memory that has already been freed a use-after-free vulnerability or sending...

CVE-2026-89474

A flaw was found in the Linux kernel's power supply subsystem, specifically within the bq256xx driver. This vulnerability occurs when a USB work item attempts to access a charger object after it has been freed. This timing issue can lead to a use-after-free condition, potentially causing system...

CVE-2026-89463

A flaw was found in the Linux kernel's ucs1002 power supply driver. The driver does not properly cancel a delayed work item during device removal, leading to a use-after-free vulnerability. This issue allows the system to attempt to access memory that has already been freed, which can result in...

CVE-2026-80982

A flaw was found in the Linux kernel's Shared Memory Communications SMC network protocol. A race condition occurs when a network connection is closed while the system is still processing its receive buffer pages. This can lead to a use-after-free vulnerability, where the system attempts to access...

CVE-2026-89747

A flaw was found in the Linux kernel's tracing component. A local attacker could exploit a use-after-free vulnerability, a type of memory corruption, by manipulating the tracepipe functionality. This occurs when the system attempts to read from memory that has already been released, leading to...

CVE-2026-89625

A flaw was found in the Linux kernel's HID Human Interface Device Sony driver, affecting Guitar Hero Live GHL dongles. A race condition occurs during the driver unbinding process where a periodic timer can be re-armed after the memory it uses has been freed. This Use-After-Free UAF vulnerability...

CVE-2026-89468

A flaw was found in the Linux kernel's lp8788-charger component. During the removal of the lp8788-charger, a race condition can occur where work can be queued and executed after the associated memory has been freed. This use-after-free vulnerability could lead to system instability or a denial of...

CVE-2026-89472

A flaw was found in the Linux kernel's power supply charger-manager component. A race condition exists where the system frees charger regulators before their corresponding sysfs entries are unregistered. A local attacker can exploit this by performing a concurrent write to a charger's...

CVE-2026-89661

A flaw was found in the Linux kernel's Network File System Daemon NFSD. A local administrator with CAPSYSADMIN capabilities can trigger a use-after-free vulnerability by writing to /proc/fs/nfsd/unlockfilesystem after the NFSD server has shut down.
