Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: net/tls: Fail tls_sw_splice_read()
after a failed async decrypt When an async decrypt fails, tls_decrypt_done() records the error in
ctx->async_wait.err and calls tls_err_abort(), which stores it in sk_err. tls_sw_recvmsg() and
tls_sw_read_sock() each read async_wait.err once they hold the reader lock and fail the call: a record
that did not authenticate breaks the connection. tls_sw_splice_read() has no such check, and sk_err does
not stand in for one. tls_rx_rec_wait() tests sk_err only inside the loop it skips whenever a record is
already parsed, and the first reader to reach sock_error() clears it, while async_wait.err persists. A
splice therefore keeps delivering records on a connection that recvmsg() and read_sock() refuse to read.
Read async_wait.err in tls_sw_splice_read() as the other two readers do. (CVE-2026-80904)

Solution

Update the sys-kernel/cchost-kernel-6_18 library and its related packages to version 20085.0.0 or later.
