USN-8631-4 linux-azure-fde-5.15 vulnerabilities

Siebe Devroe, Héloïse Gollier, and Mathy Vanhoef discovered that the WiFi implementation in the Linux kernel did not properly handle aggregated frames in mesh networks, due to an incorrect fix for CVE-2020-24588. A physically proximate attacker could use this issue to inject packets. CVE-2025-275...

CVE-2026-74464

A flaw was found in the Open vSwitch OVS component of the Linux kernel. This vulnerability occurs when a packet becomes unparseable during a flow key update operation. This can lead to a memory leak, potentially allowing a remote attacker to cause a denial of service by exhausting system resource...

CVE-2026-72428

A flaw was found in the Berkeley Packet Filter BPF component of the Linux kernel. An incorrect calculation of the stack slot index during Spectre v4 sanitization checks could result in certain memory bytes not being properly sanitized. This vulnerability might allow an attacker to potentially...

PCP: PCP: Denial of Service due to signed integer overflow

A signed integer overflow in the PCP pmGetPDU function can be exploited via crafted network packets during PDU processing or SASL negotiation. This permanently blinds the affected daemon, resulting in a total denial of service DoS for subsequent packet reads...

openssl: NULL pointer dereference in QUIC server initial packet handling

A flaw was found in the OpenSSL QUIC Quick UDP Internet Connections server. A remote attacker could send a specially crafted QUIC initial packet with an invalid token. If the server's address validation is explicitly disabled, this could lead to a NULL pointer dereference, causing the server...
