In the Linux kernel, the following vulnerability has been resolved:

tls: fix race between tx work scheduling and socket close

Similarly to previous commit, the submitting thread (recvmsg/sendmsg)may exit as soon as the async crypto handler calls complete().Reorder scheduling the work before calling complete().This seems more logical in the first place, as it'sthe inverse order of what the submitting thread will do. (CVE-2024-26585)

netfilter: nf_tables: use timestamp to check for set element timeout (CVE-2024-27397)

net: bridge: mcast: wait for previous gc cycles when removing port (CVE-2024-44934)

In the Linux kernel, the following vulnerability has been resolved:

netfilter: ctnetlink: use helper function to calculate expect ID (CVE-2024-44944)

Tenable has extracted the preceding description block directly from the tested product security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
