An update of the linux package has been released.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - In the Linux kernel, the following vulnerability has been resolved: binder: fix async_free_space     accounting for empty parcels In 4.13, commit 74310e06be4d (android: binder: Move buffer out of area     shared with user space) fixed a kernel structure visibility issue. As part of that patch, sizeof(void *)     was used as the buffer size for 0-length data payloads so the driver could detect abusive clients sending     0-length asynchronous transactions to a server by enforcing limits on async_free_size. Unfortunately, on     the free side, the accounting of async_free_space did not add the sizeof(void *) back. The result was     that up to 8-bytes of async_free_space were leaked on every async transaction of 8-bytes or less. These     small transactions are uncommon, so this accounting issue has gone undetected for several years. The fix     is to use buffer_size (the allocated buffer size) instead of size (the logical buffer size) when     updating the async_free_space during the free operation. These are the same except for this corner case of     asynchronous transactions with payloads < 8 bytes. (CVE-2021-46935)

Note that Nessus relies on the presence of the package as reported by the vendor.
