CVE-2026-64044

Concrete details confirm CVE-2026-64044 fix in the Linux kernel’s OpenVPN peer handling. The error path in ovpn_nl_peer_new_doit() previously called ovpn_peer_release() directly instead of ovpn_peer_put(), bypassing the kref, risking use-after-free when a caller holds a ref during an in-flight op...

CVE-2026-64044 ovpn: respect peer refcount in CMD_NEW_PEER error path

In the Linux kernel, the following vulnerability has been resolved: ovpn: respect peer refcount in CMDNEWPEER error path ovpnnlpeernewdoit's error path calls ovpnpeerrelease directly rather than ovpnpeerput, bypassing the kref. The accompanying comment "peer was not yet hashed, thus it is not use...

CVE-2026-64042 vfio/pci: Check BAR resources before exporting a DMABUF

In the Linux kernel, the following vulnerability has been resolved: vfio/pci: Check BAR resources before exporting a DMABUF A DMABUF exports access to BAR resources and, although they are requested at startup time, we need to ensure they really were reserved before exporting. Otherwise, it's...

CVE-2026-64035

The CVE-2026-64035 entry concerns the Linux kernel igc driver: igc_fpe_init_smd_frame() failed to set the tx buffer type for SMD frames, causing igc_tx_buffer entries to retain a stale XDP/XSK type. This can lead TX completion to follow an incorrect cleanup path. The fix is to set the buffer type...

CVE-2026-64028

In the Linux kernel tracing subsystem, CVE-2026-64028 affects hist_field_name() in the fully-qualified VAR_REF/EXPR path: when snprintf() truncation returns NULL, callers mistakenly dereference NULL in strcat(expr, hist_field_name(field, 0)) and in a sort-key strcmp, potentially leading to NULL d...
