CVE-2006-5749: The isdn_ppp_ccp_reset_alloc_state function in drivers/isdn/isdn_ppp.c in the Linux 2.4 kernel before 2.4.3...

The isdn_ppp_ccp_reset_alloc_state function in drivers/isdn/isdn_ppp.c in the Linux 2.4 kernel before 2.4.34-rc4 does not call the init_timer function for the ISDN PPP CCP reset state timer, which has unknown attack vectors and results in a system crash.

Security readout for executives and security teams

This is an old Linux 2.4 kernel flaw that can crash affected systems. The issue is in ISDN PPP compression-control reset handling. Public data does not describe the attack path, and CISA KEV status is false, so urgency depends on whether any legacy Linux 2.4 systems remain in use. Exposure is most likely limited to legacy Linux 2.4 deployments, especially systems using or carrying ISDN PPP kernel functionality. Modern supported Linux kernels are unlikely to be relevant based on the provided sources. Treat this as a legacy-platform risk, not a broad modern emergency. If Linux 2.4 assets exist in production, prioritize remediation because a crash-level kernel flaw can affect availability. Mitigation focus: Inventory systems still running Linux 2.4 kernels.; Prioritize kernels older than 2.4.34-rc4 for remediation review.; Apply the relevant vendor kernel advisory or supported kernel update..
