GHSA-XJ3H-WWXQ-GFCJ Cloudreve: Storage-quota TOCTOU race allows quota bypass and storage-based denial of service

Summary Cloudreve v4 splits the storage-quota check reading the user's used bytes and comparing them to MaxStorage and the charge incrementing users.storage into two non-atomic steps in the PrepareUpload code path. This creates a Time-of-Check to Time-of-Use TOCTOU race condition. Any authenticat...

kernel: RDMA/rxe: Fix a use-after-free problem in rxe_mmap

A flaw was found in the Linux kernel's RDMA/rxe component. A race condition in the rxemmap function, which manages memory for Remote Direct Memory Access RDMA operations, can lead to a use-after-free vulnerability. A local attacker could exploit this timing issue to cause a system crash, resultin...

kernel: Bluetooth: serialize accept_q access

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition exists in the handling of the acceptq within the btsockpoll function due to a lack of synchronization. This could allow a local attacker to cause a denial of service by manipulating socket operations during child teardow...

kernel: Linux kernel Bluetooth: Denial of Service via race condition in hidp_session_thread

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition in the hidpsessionthread can lead to a use-after-free vulnerability. This occurs when a timer is active while its deletion function is called, causing memory to be accessed after it has been freed. A local attacker could...

kernel: crypto: af_alg - Disallow concurrent writes in af_alg_sendmsg

A race condition was found in the Linux kernel cryptographic user API, AFALG in the way concurrent writes to the same AFALG socket are handled. Interleaved data and inconsistent internal socket state may result. A local user could use this flaw to crash the system or corrupt cryptographic operati...

CVE-2026-86805

A flaw was found in glibc, specifically within its dynamic loader ld.so. A local attacker can exploit a time-of-check to time-of-use TOCTOU race condition to escalate privileges and execute arbitrary code. This occurs when the dynamic loader expands $ORIGIN in DTRPATH for setuid/setgid programs,...

In the Linux kernel, the following vulnerability has been resolved: nullblk: serialize configfs attribute updates with device setup The attribute store methods generated with NULLBDEVICEATTR refuse to change the configuration of a live device by testing NULLBDEVFLCONFIGURED, but that flag is only...

SUSE CVE-2026-90393

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix potential UAF in bpfnetnslinkupdateprog In bpfnetnslinkupdateprog, the checks for oldprog and prog type are currently performed locklessly before acquiring netnsbpfmutex. This creates a race condition that can lead to a...

SUSE CVE-2026-90395

In the Linux kernel, the following vulnerability has been resolved: power: supply: isp1704charger: cancel work on remove The USB notifier and initial VBUS detection can schedule isp-work. The remove path unregisters the notifier and power supply, but does not wait for queued or running work befor...

SUSE CVE-2026-90431

In the Linux kernel, the following vulnerability has been resolved: remoteproc: Prevent crash handling to race with rprocdel There's no synchronization between rproccrashhandlerwork and rprocdel, as such it's possible for a driver to be removed while crash-handler work is scheduled, or even...

SUSE CVE-2026-91203

A flaw was found in cockpit-files. This vulnerability allows a local attacker to exploit a timing issue, known as a symlink race condition, during privileged file operations such as changing file ownership or permissions. By manipulating directory entries and winning this race, the attacker can...

SUSE CVE-2026-91205

A flaw was found in cockpit-files. A local unprivileged attacker can exploit a race condition during directory creation with owner assignment. By controlling a writable parent directory, the attacker can replace a newly created directory with a symbolic link symlink before the ownership change...

SUSE CVE-2026-93096

In the Linux kernel, the following vulnerability has been resolved: cxl/features: Serialize multi-part Get/Set Feature transfers A Get or Set Feature payload larger than the mailbox payload size is split into several mailbox commands. mboxmutex only serializes individual mailbox commands and is...

SUSE CVE-2026-93138

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix vmlinux BTF prep race in bpfgetbtfvmlinux bpfgetbtfvmlinux lazily parses the vmlinux BTF under the bpfverifierlock, but publishes the result through a plain store and re-checks it through a plain lockless load. Nothing...

SUSE CVE-2026-93169

In the Linux kernel, the following vulnerability has been resolved: dmaengine: zynqmpdma: fix race between runtime PM and device removal In zynqmpdmaremove, runtime PM was disabled only after checking state and doing a manual suspend. This can race with runtime PM in the remove/unbind rmmod path...
