SUSE CVE-2026-93096
In the Linux kernel, the following vulnerability has been resolved: cxl/features: Serialize multi-part Get/Set Feature transfers A Get or Set Feature payload larger than the mailbox payload size is split into several mailbox commands. mboxmutex only serializes individual mailbox commands and is...
PT-2026-94876
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the cxlctl set feature function where the output buffer size is determined by the user-provided fwctl rpc.out len without verifying if it is large enough to accommodat...
PT-2026-94877
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A heap out-of-bounds write exists in the cxlctl get feature function. The issue occurs because the output buffer is sized based on the fwctl rpc.out len value provided by the user, while...
DEBIAN-CVE-2026-89571
In the Linux kernel, the following vulnerability has been resolved: cxl/features: bound fwctl command payload to the input buffer fwctlcmdrpc copies cmd-inlen bytes into inbuf = kvzalloccmd-inlen and passes inbuf and inlen to -fwrpc. The CXL callback cxlctlfwrpc ignores inlen and never checks the...

CVE-2026-89571
This is an out-of-bounds read in the Linux kernel's CXL (Compute Express Link) features subsystem. The fwctl_cmd_rpc() function copies user-supplied data into a fixed-size buffer, but the downstream cxlctl_set_feature() callback validates the user-controlled op_size only from below, never against...

PT-2026-90287
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the CXL features of the Linux kernel where the cxlctl fw rpc callback fails to validate the user-controlled op size variable against the input buffer length in len. In...
Linux kernel Heap Buffer Overflow DoS
The vulnerability of the pdsfcfwrpc function in the drivers/fwctl/pds/main.c file of the Linux kernel is related to the copying of buffers without checking the size of the input data. Exploiting this vulnerability could allow an attacker to cause a service failure...
