CVE-2026-98827

A flaw was found in the Linux kernel's ath9khtc wireless network driver. An attacker transmitting large network packets can trigger a Denial of Service DoS or system crash through memory corruption. This issue occurs because the driver limits aggregated transmit packets only by count rather than...

DEBIAN-CVE-2026-115863

ConnMan through 2.0 has a stack-based buffer overflow via a DHCPv6 Reply message. This occurs in getdomains in gdhcp/client.c. It copies a fixed NSMAXDNAME 1025 bytes from a DHCPv6 DOMAINLIST option 24 value into a 1026-byte stack buffer dnsname regardless of the actual option length, then walks...
