CVE-2026-90407

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix overreads in ath11kwmiprocesscsaswitchcountevent There is no policy entry for WMITAGPDEVCSASWITCHCOUNTSTATUSEVENT, so the parse infrastructure does not enforce a minimum length for the event struct. Additionally...

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix leak in ath11kservicereadyextevent Currently, during ath11kservicereadyextevent processing, svcrdyext.macphycaps can be allocated during TLV parsing. This is a temporary allocation that is freed on the success...

CVE-2026-90361

CVE-2026-90361 is a memory leak in the Linux kernel's ath11k WiFi driver, specifically in the ath11k_service_ready_ext_event() function. During TLV parsing, svc_rdy_ext.mac_phy_caps is allocated as a temporary buffer. It is freed on the success path but not on the error path , so if TLV parsing s...

netty-codec-haproxy: Netty-codec-haproxy: Denial of Service via malformed HAProxy message

A flaw was found in netty-codec-haproxy, a component of the Netty network application framework. A remote attacker can exploit this vulnerability by sending a specially crafted HAProxy message with a malformed PP2TYPESSL TLV Type-Length-Value header. This can lead to an IndexOutOfBoundsException...
