CVE-2024-56729: Linux Kernel

Medium severity, CVSS 4.7. EPSS: 0.2% chance of exploitation in the next 30 days.

In the Linux kernel, the following vulnerability has been resolved: smb: Initialize cfid->tcon before performing network ops Avoid leaking a tcon ref when a lease break races with opening the cached directory. Processing the leak break might take a reference to the tcon in cached_dir_lease_break() and then fail to release the ref in cached_dir_offload_close, since cfid->tcon is still NULL.

Affected products

• Linux Linux Kernel: from 6.1, before 6.6.64 (fixed in 6.6.64); from 6.7, before 6.11.11 (fixed in 6.11.11); from 6.12, before 6.12.2 (fixed in 6.12.2)
