CVE-2026-64360

CVE-2026-64360 affecting the Linux kernel’s HFS/HFS+ code (hfs_bnode_read) was fixed by zero-initializing the output buffer at the start of hfs_bnode_read to ensure deterministic zero values across all paths. The bug allowed early returns when is_bnode_offset_valid() failed or when check_and_corr...

CVE-2026-64339

CVE-2026-64339 affects the Linux kernel USB IO stack (usbio_bulk_msg). A malicious device that advertises a large bulk OUT and small bulk IN endpoint can set bpkt_len (from bpkt->len) to exceed rxbuf_len, causing memcpy to read past rxbuf and leak adjacent slab memory via i2c-dev. The code alr...

CVE-2026-64333

The CVE-2026-64333 issue affects the Linux kernel USB serial driver digi_acceleport. The vulnerability was caused by digi_write_inb_command() not properly handling timeouts: it could update the transfer buffer and resubmit the URB on timeout, and for break-control type commands with no timeout it...

CVE-2026-64304

In the Linux kernel, CVE-2026-64304 affects the crypto qat driver: the RSA CRT component handling in qat_rsa_setkey_crt() can write out of bounds when a CRT component exceeds the allocated half-key buffer, causing memory corruption. The root cause is that the generic RSA key parser bounds compone...
