CVE-2026-74689

A slab-out-of-bounds read vulnerability in the Linux kernel's ATM (Asynchronous Transfer Mode) network protocol, specifically in vcc_setsockopt(). The root cause is an ineffective optlen check: when __SO_LEVEL_MATCH evaluates to false, the length validation is short-circuited and bypassed. Additi...

CVE-2026-74681

CVE-2026-74681 is a bug in the Linux kernel usbio driver (under drivers/usb/misc/). In usbio_bulk_msg(), the EMSGSIZE check incorrectly compares ibuf_len (the bulk IN/receive buffer size) against txbuf_len (the bulk OUT endpoint size) instead of rxbuf_len. Both values are set independently from d...
