Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: net/mlx5e: fixed a double-free in arfscreategroups. When the memory allocated by kvzalloc fails, arfscreategroups will free ft-g and return an error. However, arfscreatetable, the only function calling arfscreategroups, will hold...

CVE-2026-93186

CVE-2026-93186 affects the Linux kernel CXL mailbox (cxl/mbox) subsystem. The CXL_MEM_SEND_COMMAND ioctl bounds the user-supplied in.size to the mailbox payload size but leaves out.size unbounded. The subsequent call to kvzalloc(out.size) in cxl_mbox_cmd_ctor() allows a user-controlled oversized ...

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...
