CVE-2022-4744 (GCVE-0-2022-4744)

Vulnerability from cvelistv5 – Published: 2023-03-30 00:00 – Updated: 2025-02-14 15:45

Summary

A double-free flaw was found in the Linux kernel’s TUN/TAP device driver functionality in how a user registers the device when the register_netdevice function fails (NETDEV_REGISTER notifier). This flaw allows a local user to crash or potentially escalate their privileges on the system.

Severity ?

7.8 (High)

CVE-2022-4269 (GCVE-0-2022-4269)

Vulnerability from cvelistv5 – Published: 2022-12-05 00:00 – Updated: 2025-04-14 18:10

Summary

A flaw was found in the Linux kernel Traffic Control (TC) subsystem. Using a specific networking configuration (redirecting egress packets to ingress using TC action "mirred") a local unprivileged user could trigger a CPU soft lockup (ABBA deadlock) when the transport protocol in use (TCP or SCTP) does a retransmission, resulting in a denial of service condition.

Severity ?

5.5 (Medium)
