Severity ?
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
In the Linux kernel, the following vulnerability has been resolved: tls: fix race between async notify and socket close The submitting thread (one which called recvmsg/sendmsg) may exit as soon as the async crypto handler calls complete() so any code past that point risks touching already freed data. Try to avoid the locking and extra flags altogether. Have the main thread hold an extra reference, this way we can depend solely on the atomic ref counter for synchronization. Don't futz with reiniting the completion, either, we are now tightly controlling when completion fires.

Per kernel scoring guidance, kTLS bugs triggered by remote peer data are Network.\nAC:L - The attacker controls both sides of the race \u2014 it supplies the data that triggers the async crypto completions and drives the socket teardown (locally via its own close(), remotely by ending the request/connection so the server closes) \u2014 and can retry across thousands of concurrent connections until the window is won.\nPR:N - There is no capability or authorization check anywhere in net/tls; a remote peer of a public kTLS server needs no credentials, and a local attacker needs only an ordinary unprivileged socket to set the TLS ULP and install keys.\nUI:N - No victim action is required; the socket close that closes the race is ordinary application behavior the attacker induces, not a user-performed operation.\nS:U - The corruption is confined to kernel slab memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\nC:H - The freed `tls_sw_context_rx`/`tls_sw_context_tx` comes from a generic kmalloc cache and can be reclaimed by attacker-controlled objects, so the use-after-free gives control over freed-object contents and can be leveraged for kernel memory disclosure.\nI:H - The callback performs writes into the freed object (`spin_unlock_bh`, `test_and_set_bit` on `tx_bitmask`) and queues a `delayed_work` residing in freed memory whose function pointer is later dereferenced, yielding heap corruption at known offsets and a control-flow hijack primitive.\nA:H - The use-after-free reliably produces slab corruption, oopses and panics, and the lost-wakeup half of the race can leave the submitting thread blocked forever in uninterruptible sleep holding the socket."

Per kernel scoring guidance, kTLS bugs triggered by remote peer data are Network.\\nAC:L - The attacker controls both sides of the race \\u2014 it supplies the data that triggers the async crypto completions and drives the socket teardown (locally via its own close(), remotely by ending the request/connection so the server closes) \\u2014 and can retry across thousands of concurrent connections until the window is won.\\nPR:N - There is no capability or authorization check anywhere in net/tls; a remote peer of a public kTLS server needs no credentials, and a local attacker needs only an ordinary unprivileged socket to set the TLS ULP and install keys.\\nUI:N - No victim action is required; the socket close that closes the race is ordinary application behavior the attacker induces, not a user-performed operation.\\nS:U - The corruption is confined to kernel slab memory within the same security authority; no VM, IOMMU, or sandbox boundary is crossed.\\nC:H - The freed `tls_sw_context_rx`/`tls_sw_context_tx` comes from a generic kmalloc cache and can be reclaimed by attacker-controlled objects, so the use-after-free gives control over freed-object contents and can be leveraged for kernel memory disclosure.\\nI:H - The callback performs writes into the freed object (`spin_unlock_bh`, `test_and_set_bit` on `tx_bitmask`) and queues a `delayed_work` residing in freed memory whose function pointer is later dereferenced, yielding heap corruption at known offsets and a control-flow hijack primitive.\\nA:H - The use-after-free reliably produces slab corruption, oopses and panics, and the lost-wakeup half of the race can leave the submitting thread blocked forever in uninterruptible sleep holding the socket.\"}]}], \"affected\": [{\"repo\":
