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...

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: 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...

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...
