CVE-2026-63996

In the Linux kernel, the following vulnerability has been resolved: ethtool: cmis: require exact CDB reply length Malicious SFP module could respond with rpllen longer than what cmiscdbprocessreply expected, leading to OOB writes. Malicious HW is a bit theoretical but some modules may just be bug...

CVE-2026-63992 tunnels: do not assume transport header in iptunnel_pmtud_check_icmp()

In the Linux kernel, the following vulnerability has been resolved: tunnels: do not assume transport header in iptunnelpmtudcheckicmp In some cases, iptunnelpmtudcheckicmp can be called while skb transport header is not set. This triggers an out-of-bound access, because typeofskb-transportheader0...

CVE-2026-63960

In the Linux kernel, CVE-2026-63960 affects usb: typec: wcove by allowing wcove_read_rx_buffer() to copy the PD RX FIFO into struct pd_message beyond its bounds. The loop uses USBC_RXINFO_RXBYTES(info) (5-bit, max 31) while the destination is 30 bytes, enabling a mis-sized copy. Additionally, reg...

CVE-2026-63949

The CVE-2026-63949 issue is a Linux kernel auxdisplay vulnerability in which linedisp_display() unconditionally reads msg[count - 1] before confirming count > 0, allowing an OOB read on zero-length writes to the message sysfs attribute. The underlying problem occurs in the message_store() call...
