CVE-2026-68313
Detail
Received This CVE record has recently been published to the CVE List and has been included within the NVD dataset.
Description
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.
