UBUNTU-CVE-2025-68765: Low severity ubuntu/linux-hwe-edge vulnerability
In the Linux kernel, the following vulnerability has been resolved: mt76: mt7615: Fix memory leak in mt7615mcuwtblstaadd() In mt7615mcuwtblstaadd(), an skb sskb is allocated. If the subsequent call to mt76connacmcuallocwtblreq() fails, the function returns an error without freeing sskb, leading to a memory leak. Fix this by calling devkfreeskb() on sskb in the error handling path to ensure it is properly released.
