SUSE CVE-2026-64541

In the Linux kernel, the following vulnerability has been resolved: net/smc: fix UAF in smccdcrxhandler by pinning the socket smccdcrxhandler looks up the connection by token under the link group's connslock, drops the lock, and then dereferences conn and the smcsock derived from it, ending in...

EUVD-2026-49783

Accesses to the CMOS memory contents are done using an indirect IO port pair. Therefore Xen needs to cache the guest chosen index, and one of the usages of the index didn't take the necessary locking to avoid concurrent changes. As a result, a guest could change the index after it being checked,...

CVE-2026-64433

A flaw was found in the Linux kernel's Bluetooth Management MGMT subsystem. A use-after-free UAF vulnerability exists in the adddevicecomplete function. This occurs because the function does not properly acquire a lock before accessing connection parameters, allowing a concurrent device removal...
