Threats Tagged 'cve-2025-37861'

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fix(es): * kernel: scsi: mpi3mr: Synchronous access b/w reset and tm thread for reply queue (CVE-2025-37861) * kernel: Linux kernel: Denial of Service due to a deadlock in hugetlb folio migration (CVE-2026-23097) * kernel: scsi: target: iscsi: Fix use-after-free in iscsit_dec_session_usage_count() (CVE-2026-23193) * kernel: ALSA: aloop: Fix racy access at PCM trigger (CVE-2026-23191) * kernel: Linux kernel: Denial of service and memory corruption in RDMA umad (CVE-2026-23243) * kernel: Linux kernel KVM: Privilege escalation or denial of service due to improper shadow page table entry handling (CVE-2026-23401) * kernel: nfsd: fix heap overflow in NFSv4.0 LOCK replay cache (CVE-2026-31402) * kernel: crypto: algif_aead - Revert to operating out-of-place (CVE-2026-31431) For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

In the Linux kernel, the following vulnerability has been resolved: scsi: mpi3mr: Synchronous access b/w reset and tm thread for reply queue When the task management thread processes reply queues while the reset thread resets them, the task management thread accesses an invalid queue ID (0xFFFF), set by the reset thread, which points to unallocated memory, causing a crash. Add flag 'io_admin_reset_sync' to synchronize access between the reset, I/O, and admin threads. Before a reset, the reset handler sets this flag to block I/O and admin processing threads. If any thread bypasses the initial check, the reset thread waits up to 10 seconds for processing to finish. If the wait exceeds 10 seconds, the controller is marked as unrecoverable.
