- Summary
- CVE-2026-74608 affecting package kernel 6.6.150.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
smb: client: Fix use-after-free in cifstryadding_channels()
cifstryaddingchannels() takes a temporary reference to an interface before dropping ifacelock. If cifssesaddchannel() fails, it drops that reference and then increments iface->weightfulfilled.
A concurrent interface list refresh can remove the list reference while channel creation is in progress. In that case, the failure-path krefput() releases the last reference and frees iface. Updating weightfulfilled afterward then accesses freed memory.
Increment weight_fulfilled before dropping the temporary reference, keeping iface alive for the final access.
