kernel: ipvs: clear IPv4 options after rebasing tunnel ICMP errors

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. When processing Internet Control Message Protocol ICMP errors for tunneled packets, the system can incorrectly use a stale IPv4 option offset. A remote attacker could exploit this by sending a specially crafted ICMP packet,...

kernel: ipvs: reload ip header after head reallocation

A flaw was found in the Linux kernel's IP Virtual Server IPVS module. When processing network packets, a buffer reallocation can leave an IP header pointer referencing freed memory. An attacker could exploit this use-after-free condition to cause a Denial of Service DoS by crashing the system or...

kernel: ipvs: do not propagate one-packet flag to synced conns

A flaw was found in the Linux kernel's IP Virtual Server IPVS component. When a synced connection is established, it can incorrectly inherit a "one-packet" flag from its destination. This misconfiguration causes the connection's expiry process to mishandle its cleanup, leaving behind stale memory...
