SUSE CVE-2026-64101

In the Linux kernel, the following vulnerability has been resolved: fwctl: pds: Validate RPC input size before parsing The fwctl core allocates the device-specific RPC input buffer with fwctlrpc.inlen and passes that buffer to the driver callback. pdsfcfwrpc casts the buffer to struct fwctlrpcpds...

CVE-2026-64101

A flaw was found in the Linux kernel's fwctl component. Insufficient validation of the Remote Procedure Call RPC input buffer size in the pdsfcfwrpc function can lead to an out-of-bounds read. A local attacker could exploit this vulnerability by providing a specially crafted RPC input, potentiall...
