CVE-2026-64258

A flaw was found in the fuse-uring component of the Linux kernel. When a copy operation to the userspace ring buffer fails, a request can be terminated improperly, leading to a NULL pointer dereference. This vulnerability could allow a local attacker to cause a system crash, resulting in a Denial...

CVE-2026-64464

A flaw was found in the Linux kernel's xHCI eXtensible Host Controller Interface sideband functionality. A memory leak occurs in the xhciringtosgtable function because a temporary memory array is not properly released after use. This continuous leakage of memory can lead to system instability and...

CVE-2026-64300

A flaw was found in the Linux kernel's perf/aux subsystem. A use-after-free UAF vulnerability exists in the maprange function due to a race condition. This can occur when two performance events share a ring buffer, allowing a local attacker to map a memory page that has already been freed...

In the Linux kernel, the following vulnerability has been resolved: xhci: sideband: fix ring sg table pages leak xhciringtosgtable allocates a temporary pages array and uses it to build the returned sgtable with sgalloctablefrompages. The error paths free the pages array, but the success path...

CVE-2026-64464

Consolidated details show CVE-2026-64464 affects the Linux kernel xhci sideband path: xhci_ring_to_sgtable() allocates a temporary pages array used to build an sg_table via sg_alloc_table_from_pages(). On success, the temporary array isn’t freed, causing a leak each time a sideband client uses an...
