CVE-2026-23118: Linux kernel miscalculates keepalive timing
CVE-2026-23118 · published 8 months ago
Summary
The Linux kernel's communication component could sometimes read an outdated timestamp when checking if a keepalive signal is needed. This could cause the system to send unnecessary keepalive packets or miss sending them, affecting network reliability. Updating the kernel to the latest version resolves the issue.

Original advisory text
BELL-CVE-2026-23118
In the Linux kernel, the following vulnerability has been resolved:
rxrpc: Fix data-race warning and potential load/store tearing
Fix the following:
BUG: KCSAN: data-race in rxrpc_peer_keepalive_worker / rxrpc_send_data_packet
which is reporting an issue with the reads and writes to ->last_tx_at in:
conn->peer->last_tx_at = ktime_get_seconds();
and:
keepalive_at = peer->last_tx_at + RXRPC_KEEPALIVE_TIME;
The lockless accesses to these to values aren't actually a problem as the
read only needs an approximate time of last transmission for the purposes
of deciding whether or not the transmission of a keepalive packet is
warranted yet.
Also, as ->last_tx_at is a 64-bit value, tearing can occur on a 32-bit
arch.
Fix both of these by switching to an unsigned int for ->last_tx_at and only
storing the LSW of the time64_t. It can then be reconstructed at need
provided no more than 68 years has elapsed since the last transmission.
