CVE-2026-64380

The CVE-2026-64380 issue affects the Linux kernel SMB client path handling of POSIX SIDs. The root cause is in posix_info_sid_size(), which reads sid[1] to obtain the subauthority count but previously allowed buffers with only one remaining byte, potentially enabling unsafe rejection of truncated...

CVE-2026-64369 s390: Revert support for DCACHE_WORD_ACCESS

In the Linux kernel, the following vulnerability has been resolved: s390: Revert support for DCACHEWORDACCESS loadunalignedzeropad reads eight bytes from unaligned addresses and may cross page boundaries. It handles exceptions which may happen if reading from the second page results in an...

CVE-2026-64339

CVE-2026-64339 is an out-of-bounds read in the Linux kernel's usbio module (usb: misc: usbio). The function usbio_bulk_msg() copies a device-supplied length (bpkt_len) from the bulk IN buffer, but only validates it against txbuf_len instead of rxbuf_len. A malicious or malfunctioning USB device t...

CVE-2026-64295

CVE-2026-64295 affects the Linux kernel mm/page_ext API used during memory hotplug. The vulnerability arises because page_ext_iter_next may advance the iterator beyond the current valid memory region without verifying that the PFN still belongs to a valid section, which can trigger a NULL pointer...
