kernel: sctp: revalidate list cursor after sctp_sendmsg_to_asoc() in SCTP_SENDALL

A flaw was found in the Linux kernel's Stream Control Transmission Protocol SCTP implementation. A race condition exists in the SCTPSENDALL path where a cached list entry is not properly revalidated after the socket lock is temporarily released. This allows a local attacker or a remote attacker v...

PYSEC-2026-2009 virtualenv Has TOCTOU Vulnerabilities in Directory Creation

Vulnerability Summary Title: Time-of-Check-Time-of-Use TOCTOU Symlink Vulnerability in SoftFileLock Affected Component: filelock package - SoftFileLock class File: src/filelock/soft.py lines 17-27 CWE: CWE-362, CWE-367, CWE-59 --- Description A TOCTOU race condition vulnerability exists in the...

PYSEC-2026-1375 filelock has a TOCTOU race condition which allows symlink attacks during lock file creation

Impact A Time-of-Check-Time-of-Use TOCTOU race condition allows local attackers to corrupt or truncate arbitrary user files through symlink attacks. The vulnerability exists in both Unix and Windows lock file creation where filelock checks if a file exists before opening it with OTRUNC. An attack...

PYSEC-2026-1763 PDM Trojan Lockfile

Summary It's possible to craft a malicious pdm.lock file that could allow e.g. an insider or a malicious open source project to appear to depend on a trusted PyPI project, but actually install another project. Details Project foo can be targeted by creating the project foo-2 and uploading the fil...

kernel: scsi: target: iscsi: Fix use-after-free in iscsit_dec_conn_usage_count()

A use-after-free flaw was found in the Linux kernel's iSCSI target subsystem. In the iscsitdecconnusagecount function, complete is called while still holding the conn-connusagelock spinlock. The waiting thread such as iscsitcloseconnection may wake up immediately and free the iscsitconn structure...

CVE-2026-55698

A flaw was found in pnpm, a package manager. This vulnerability allows a remote attacker to achieve arbitrary code execution by committing a specially crafted package-manager lockfile pnpm-lock.yaml to a repository. When pnpm is executed, it trusts an already resolved packageManagerDependencies...
