CVE-2026-58224

A flaw was found in Samba's CTDB, the clustered database service used by Samba. Insufficient integrity validation of received CTDB protocol packets allows malformed packets containing invalid field lengths, improperly terminated strings, or inconsistent packet sizes to be processed without adequa...

CVE-2026-16529

Affects Performance Co-Pilot (PCP) components pmlogger/pmcd; issue is a signed integer overflow in PCP __pmGetPDU() that can be triggered by crafted network packets during PDU processing or SASL negotiation, permanently blinding the daemon and causing DoS on subsequent reads. Mitigation (per Red ...

UBUNTU-CVE-2026-54345

gopacket provides packet processing capabilities for Go. In version 1.6.0 and earlier, the Diameter AVP decoder computes an AVP data length by subtracting a fixed header size from an attacker-controlled AVP Length field, so a vendor-flagged AVP whose Length is smaller than the 12-byte header...

gopacket provides packet processing capabilities for Go. In version 1.6.0 and earlier, the sFlow ExtendedGatewayFlow decoder in layers/sflow.go reads an attacker-controlled 32-bit community count and AS path member count and sizes a slice allocation from those counts without bounding them against...

kernel: wifi: mac80211: drop stray 'static' from fast-RX rx_result

A flaw was found in the Linux kernel's Wi-Fi mac80211 subsystem. The ieee80211invokefastrx function uses a static variable for rxresult, which is shared across concurrent calls. This can lead to incorrect processing of Wi-Fi packets, where a packet might be mishandled or its status incorrectly...
