Title: Linux Kernel ISDN PPP Remote Denial of Service Vulnerability
Severity: MODERATE
Description:
The Linux kernel is prone to a denial-of-service vulnerability.
The attack vector of this issue is currently unknown. The vulnerability affects the 'isdn_ppp_ccp_reset_alloc_state()' function of 'drivers/isdn/i4l/isdn_ppp.c'. Reports indicate that this issue arises because the function fails to initialize an event timer prior to scheduling it with the 'add_timer()' call.
An attacker can exploit this issue to cause an affected kernel to crash, effectively denying service to legitimate users.
Versions prior to 2.4.34 are vulnerable to this issue.
