Description

In the Linux kernel, the following vulnerability has been resolved:

ice: fix memleak in ice_init_tx_topology()

Fix leak of the FW blob (DDP pkg).

Make ice_cfg_tx_topo() const-correct, so ice_init_tx_topology() can avoid
copying whole FW blob. Copy just the topology section, and only when
needed. Reuse the buffer allocated for the read of the current topology.

This was found by kmemleak, with the following trace for each PF:
[] kmemdup_noprof+0x1d/0x50
[] ice_init_ddp_config+0x100/0x220 [ice]
[] ice_init_dev+0x6f/0x200 [ice]
[] ice_init+0x29/0x560 [ice]
[] ice_probe+0x21d/0x310 [ice]

Constify ice_cfg_tx_topo() @buf parameter.
This cascades further down to few more functions.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
