CVE-2026-97924

The Linux kernel contains a vulnerability in the tracing/user_events component. The destroy_user_event() function incorrectly destroys an event's fields before attempting to remove the trace event call. If the removal fails (e.g., returning -EBUSY because the event is still enabled), the event re...

CVE-2026-97591

The Linux kernel (specifically the s390/crypto architecture) contained a logic flaw in how it handled return codes when pushing requests to the crypto engine. In the PHMAC function, the crypto_transfer_hash_request_to_engine() call could return EBUSY in addition to EINPROGRESS to signal a success...

EUVD-2026-86899

In the Linux kernel, the following vulnerability has been resolved: s390/crypto: Fix handling of EBUSY in PHMAC when req is pushed to crypto engine When a request is transferred to the engine via cryptotransferhashrequesttoengine there are two return codes signaling a successful transfer:...

EUVD-2026-86896

In the Linux kernel, the following vulnerability has been resolved: s390/crypto: Map EBUSY to EIO when key conversion fails repeatedly When hardware persistently returns -EBUSY after exhausting retries, the error propagates to cryptofinalizerequest. The crypto API's completion wrapper treats -EBU...

CVE-2026-97588

The Linux kernel contains a vulnerability in the s390/crypto component where persistent -EBUSY errors from hardware during key conversion result in the error being swallowed by the crypto API's completion wrapper. Because the wrapper treats -EBUSY as a queueing status, the completion callback fai...

CVE-2026-90087

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: do not leak an hciconn when a second LE connect is rejected createleconncomplete decides whether the failed connection is still pending by comparing it against hcilookupleconnect, which returns the first LE connection ...

CVE-2026-90087

CVE-2026-90087 is a Linux kernel Bluetooth (HCI) resource leak affecting the handling of concurrent LE (BLE) connection attempts. When two connections are in BT_CONNECT simultaneously—specifically one on the passive scan path with HCI_CONN_SCANNING set—create_le_conn_complete() may match the wron...

Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: crypto: seqiv – Properly handles the EBUSY error. Since seqiv only handles the special return value of EINPROGERSS, it means that in all other cases, it will free the data related to the request. However, since the caller of seqi...

In the Linux kernel, the following vulnerability has been resolved: net/tls: The use-after-free issue in the -EBUSY error handling path of tlsdoencryption has been fixed. The -EBUSY handling in tlsdoencryption, introduced with commit 859054147318 “net: tls: handle backlogging of crypto requests”,...

CVE-2026-89499

CVE-2026-89499 affects the Linux kernel ring-buffer component. When the remote swap_reader_page callback returns -EBUSY (e.g., during an event storm on a small buffer), __rb_get_reader_page_from_remote() incorrectly continues with an unchanged reader ID and rearranges the local page list as thoug...
