GHSA-CQGJ-H8VF-4W59 Acknowledgement extension out of memory
Impact Bad clients that always send a fixed batch value while the server is using the acknowledgement extension can cause the unacknowledged message queue to grow indefinitely, eventually resulting in an OutOfMemoryError. Such bad clients would always send: json "channel": "/meta/connect",...
CVE-2026-46307
A flaw was found in the Linux kernel's ath5k Wi-Fi driver. This vulnerability allows for an array-index-out-of-bounds write in the ath5ktasklettx function. An attacker could potentially trigger this by manipulating specific index values, leading to a minor data corruption. The immediate impact of...

DEBIAN-CVE-2026-31662
In the Linux kernel, the following vulnerability has been resolved: tipc: fix bcackers underflow on duplicate GRPACKMSG The GRPACKMSG handler in tipcgroupprotorcv currently decrements bcackers on every inbound group ACK, even when the same member has already acknowledged the current broadcast...
CVE-2026-31662
CVE-2026-31662 concerns the Linux kernel’s TIPc grouping protocol. The bug in tipc_group_proto_rcv() decrements bc_ackers for every inbound GRP_ACK_MSG, even if the sender already acknowledged the current broadcast round. Since bc_ackers is a 16-bit unsigned, a duplicate ACK after the last legiti...
