Title
tipc: fix infinite loop in __tipc_nl_compat_dumpit
Summary
In the Linux kernel, the following vulnerability has been resolved:
tipc: fix infinite loop in __tipc_nl_compat_dumpit
cmd->dumpit callback can return a negative errno, causing an infinite
loop due to the while(len) condition. As the loop never terminates,
genl_mutex is never released, and other tasks waiting on it starve in D
state.
Check dumpit's return value, propagate it and jump to err_out on error.
Severity
No CVSS data available.
