Low risk17th percentile - higher than 17% of all known CVEs
Summary
Use-after-free vulnerability in the Linux kernel's TLS implementation with partial reads and async decrypt. tls_decrypt_sg does not take a reference on pages from clear_skb, so put_page() in tls_decrypt_done releases them, leading to use-after-free in process_rx_list.
Risk Assessment
May lead to memory corruption, system crash, or potential remote code execution.
Recommendation
Apply the Linux kernel update that includes the fix for this issue.
Original NVD description (English source)
In the Linux kernel, the following vulnerability has been resolved: net: tls: fix use-after-free with partial reads and async decrypt tls_decrypt_sg doesn't take a reference on the pages from clear_skb, so the put_page() in tls_decrypt_done releases them, and we trigger a use-after-free in process_rx_list when we try to read from the partially-read skb.
